*Subject:* [BVARC] TTFD Antennas - N4HPG

Howdy All,

I was listening to the net last night and John, K5IZO, was encouraging 
folks to get on 75m. Yay!


I’ve been working on a project for a number of months. Some of you 
know that I use a TTFD antenna. TTFD or T2FD. It stands for Tilted 
Terminated Folded Dipole. This antenna is not widely known because 
it’s not featured in any ARRL publications – at least since 1949. 
There are some good reference sources such as the RSGB wire antenna 
book. There are also some detractors that don’t understand the theory 
of operation.


Here’s a link to the original article:

http://www.scribd.com/doc/42625655/An-Experimental-All-Band-Nondirectional-Transmitting-Antenna-T2FD

You’ll notice that the antenna is a 600-ohm design. It is a balanced 
antenna.


Perhaps Rick Hiller and I should give a presentation on it.

I’ve been using the BW version for a number of  years, but want to 
run higher power. That means a better matching transformer for 50:600 
ohms and also a more robust terminating resistor. The antenna works 
well from 75 to 10m with 1.5:1 SWR or better on all bands. This is 
because it’s a traveling wave antenna. Mismatch is soaked up by the 
terminating resistor. No tuner is needed. The antenna works from the 
lowest frequency up. That means a 80m antenna works on all bands from 
80-10m. A shorter antenna works from 40-10m. BW says 6m, but I’ve not 
tested my high-power balun for 6m yet. I never promise what I haven’t 
tested.


I’m hoping to bring a completed unit of the high-power design to the 
club meeting on 9/10 so y’all can look at it. I should probably fire 
up N4HPG.com website and post some pictures.


_If you can have only 1 antenna, this is the one to have. I like to 
hunt DX and change bands without having to tune. Get as long an 
antenna as possible!_




The folks at BW now want $825 for their version. That’s insane! But 
they sell mostly to military and governments.


I’m making one antenna for myself that will be all my build. I’m also 
making a heavy-duty one for N5XZ. Being gainfully unemployed and 
having a workshop, I’m testing the waters to see if others might want one.


When we put up an antenna, the neighbors usually notice. I’m making my 
version with 14awg white MTW wire and clear, acrylic spacers for the 
antenna and the ladder line. The balun box mounts on the wall and 
transforms the 50 ohm unbalanced to 600 ohm balanced. It’s a 6x6x4 box 
because there are 4 toroids.


Based upon present materials, I believe I can produce the standard 
antenna – 1kW for normal operation for $349. I’m still working on the 
N5XZ 1.5kW RTTY Contesting version that will be a bit more.


If you want to build your own, feel free to steal my design!

For those who would like a built and tested unit, let me know. I’m 
trying to decide if I should get into the antenna business.


73!

Re: [BVARC] Pictures of the antenna for my party.

2015-10-23 Thread Gary Sitton via BVARC

Randy:

Yuh know, the T2FDs can be deployed vertically,
i.e. as a VTFD.  This could allow a stealth antenna
a few feet from a tree trunk with the bottom about
8 ft. from the ground for RF safety and performance.

A 40 meter VTFD would only need to be about 33'
long and be center fed with the coax tethered next to
the tree trunk itself.  Crazy idea? Comments welcome!

   Yeah, I heard about it last week.  It's a

I don't think Flex Radio is too worried about

Re: [BVARC] New Icom Rig -- IC 7300

2015-08-30 Thread Gary Sitton via BVARC

Scott:

Well, the DDC/DUC (Direct Down/UP Conversion) has
a single A/D converter followed by digital quadrature
mixer in the form of an FPGA which outputs a digital I,Q
stream.  QSD RXs have a hybrid quadrature mixer (basically
analog) followed by two A/D converters producing the I,Q
stream.  For those unfamiliar with the notation, the I and Q

the keys may still be available.  See my QRZ page

Randy,

I agree with Rick H and Bill C.  I am in the 20WPM comfort zone and 
25+ during contests.  I also have a key collection on display (~100 
keys). I have several examples of each as discussed below if you want 
to see/feel/touch/use any on the air.


Used prices are "typical" for good working condition (8 of 10).  If 
you want a "cream puff," then more.  Shipping varies but typically is 
around $10.


For straight keys, I really like the Nye Master Straight Key with the 
Navy Knob (has a slightly sloped front) as Rick mentioned.  You can 
usually find them on E-Bay for around $20-25.  Regardless, be sure you 
get the Navy Knob.


I agree with Rick that if you are under 18WPM, then use a straight key 
at first.  It is important that you get a good "feel" for keying.


As far as a paddle is concerned, see the discussion from Rick. 
 Assuming that you are under 35 WPM, then you could use either single 
paddle or a true Iambic.  If you are 35+ WPM, then a true Iambic is 
probably best.


In my opinion, after the straight key, just go straight for the 
iambic.  You ask for the "Best bang for the buck";  that would be the 
Bencher BY-1.  This is a true Iambic.  It goes for about $50 - 70 on 
E-Bay or $160 new.


I personally don't like the magnetic Iambics (vs the spring return). 
 I like a little more "feel" than these give.  Maybe if I were a 
regular op at above 30 WPM, it might make a difference.


I can't recommend any specific single paddle (though I have a few), as 
I haven't used them much.  As mentioned, after the straight key, just 
go directly to an Iambic.


I assume that you are not interested in a "bug."  I have a dozen or so 
if you want to try them.

second time.


Last time I had him working on my 12 ele LPDA at 120 feet. I was using 
a crane. He replaced the two boom-support cables. This antenna is 
above another antenna necessitating the use of a crane.


Work was performed swiftly. Leslie know the signals that crane op's 
use to talk to one another. So his experience extends to crane work.


Leslie also did some work on the lower antenna; letting me release the 
crane ($)


2. Today he replaced a rotator in my 100 foot tower and some alignment 
work of the two antennas on this tower. Again he worked very 
welland swiftly ($).


I have to recommend him to tower owners/builders. He is honest and 
 reliable. He moves around up there like no one I have ever seen.


He tells me that this is his full time job now days.

Give Leslie as call for your tower work. He has worked for numerous 
Conroe, Magnolia, and north Houston hams. I don't know how far he will 
travel for work. This can probably be negotiated.

Hi Gary:

I don’t mind your 25 cents.

What I figured out was a way to actually measure the Zo. I use an 
Oscope and a signal generator and about 3m of line under test. I 
terminate the line with a 10-turn pot.


I bang a 1MHz square wave into one end and watch the scope while 
carefully adjusting the pot. When it’s matched, the square wave is not 
distorted and the amplitude is at the same ratio as the change in 
impedance from 50 ohms! The scope is In high-Z mode.


The interesting thing is how the values are close to the calculated. 
The lines in the 9:1 are calculated roughly 200 ohms, but measure 190.




Jerry Sevick told us his experimental results, but didn’t tell us how 
to make a balun. Yes, he added a tremendous amount of knowledge to the 
art, but I’m making up the backend of how one actually builds it.


Sadly, the photographs in the publications are such poor quality as to 
only give an idea of the fabrication of the test jigs he made. Lots of 
really good analysis, but I’d love to see his raw data.

Bill:

   I'm sticking my neck out here, but here's an
idea for window line transmission lines.  Use
the weighted average of the dielectric constant
(dc) for air and the feed line spacer/insulator.  In
the case of real ladder line, the dc is very close
to that of air or approximately a vacuum.

The window line I use has 14 AWG wire and is
actually spected at closer to 400 Ohms than the
450 Ohms usually associated with window lines
using 18 AWG wire.  Line losses go up as the
ohmic dielectric losses in the separator material
is more dense, e.g. solid twin lead is the worst.

   Another consideration is velocity factor.  True
air spaced ladder line is about 0.99 whereas
ladder lines are more like 0.95.  This is all mainly
dependent on the dc as the permeability of most
dielectric materials is that of air or a vacuum.
Again, pardon my 1.5 cents worth on this Bill.

All,

I’ve received a number of emails from you and I’ll send out a reply 
to the group.


This is an on-going experiment that I hope to have wrapped up in a 
few weeks. I’m waiting on some material to arrive from eBay.


Action items:

 1. Using the PVC box instead of an aluminum box necessitates using a
feed line choke. The material is coax to wind to make the choke.
 2. Testing with a 500 ohm terminator. I’m fabricating a test jig
that will let me use jumpers to select the values for further
testing.
 3. Some have asked for detailed build instructions instead of paying
me . Of course. I dislike it when people hide the designs
as patented and proprietary – when it comes to ham radio.
 4. Some have asked me to do a presentation at a club meeting or 3.
My health has been slowly improving so that’s possible after the
holidaze.


Since the article was written, I’ve developed a way to actually test 
the characteristic impedance of the flat transmission lines. If you 
look at the formula, it is a function of the diameter of the wires, 
the spacing and the dielectric constant of the material – fine when 
you have a solid piece of material such as a TV twin-lead, less so 
when you have some other material.



One very important item was left out of the article and will be in 
the revised article. Grounding. There is provision for a ground lead 
on the balun; however, I’ve not installed a ground yet. The antenna, 
being balanced, does NOT require a ground for operation. This is 
especially important on 160-40m. A vertical needs a lot of ground 
plane for efficiency.


Grounding at the balun is important for SAFETY. With a wire up 50’ in 
the air, lightning happens.


Any volunteer to help me install 2 ground rods? One at the antenna 
and one for the main station ground.

   I have a similar 2nd floor shack situation (see QRZ page K5AMH).
It's very possible to put a few feet or more of ladder line inside the
shack and loop it to save space.  An antenna analyzer should show
you about how much feed line to add to solve the problem.

   What kind of antenna tuner or balun arrangement are you using?
I have a highly modified Johnson KW MatchBox which is entirely
floating from the ground (case) internally.  This assures virtually
perfect feed line current balance, i.e. no common mode currents.

Hi all,

My last antenna experiment was a center-fed zepp cut for 80
meters.  (Dipole fed in the center with 450 ohm feed line,
requiring a tuner.)

I found this antenna to be a decent multi-band antenna, with one
exception:  I never could get my MFJ manual tuner to find a match
on 40 meters.  For the other bands, it seemed to find a match
fairly easily.  As I had another antenna -- an inverted L vertical
-- for  40 meters, I shrugged this off as something to look into
later.

Well, my inverted L has succumbed to the elements and I need to
rebuild it, so I turned my attention to trying to figure out my
center-fed zepp 40 meter problem.

After much research (remember, I'm a beginner at this!), the
problem has become somewhat obvious.  One drawback to a center-fed
zepp, I have learned, is that the impedance at the second harmonic
of the lowest frequency will be very, very high.  The second
harmonic of an 80 meter antenna is 40 meters.  Oops.  Apparently
the impedance is so high the MFJ tuner can't match it.

I thought about purchasing a fancy tuner, but I remembered that
tuners aren't miracle devices.  They don't change the impedance of
the antenna and I am concerned about power loss at the tuner.  It
seems the only thing to do is to find a way to temporarily
electrically shorten the dipole when I want to operate on 40 meters.

The 'zepp is an inverted V, so the ends of each leg of the dipole
are fairly low to the ground and easily accessible.  (They
actually run along the top of my backyard fence for about 15 feet
on each side!)  What if I coiled enough of the wire such that the
second harmonic of the new length was off the 40 meter band?  Is
coiling the excess wire enough to electrically shorten the
antenna, or do I really need to run the excess wire back along the
elements (parallel to them) for this to work?

I like the coiling idea as I could just uncoil the wire on each
end, stretch it back to its original length when I want to operate
on 80 (or 60) meters.

JP:

   The new Icom IC-7300 DUC/DDC  SDR transceiver is
$1,500 and the real deal.  It covers all the 1.8 through
50 MHz bands and has an ATU and nice panadapter.
Your $1K budget limit needs to be reconsidered.  I
also think the 7300 prices may go down a bit soon.

Subject: Re: [BVARC] When all you really want is JUST A DROP!

I wouldn't worry as much about the diameter or making sure it's "eutectic"
as Mr. Crowell does. The rest of the world gets excellent results with
lead-free solders, as do I, and you can, too. I'll let you know if I see
any tin whiskers show up.

For my own part, I think Mr. Crowell focuses far too much on the solder and
far to little on the equipment and the preparation. While you can (as I
did) do excellent work with the kind of cheap crap you could buy at Radio
Shack in the late 70's, if you value your time at all, it's worth getting
good stuff, but I'm getting ahead of myself.

There are three rules for getting good solder joints. The materials to be
joined must be clean, they must be fluxed, and they must be hot. The 
material

that is normally soldered is copper, but just about any pure metal is going
to oxidize when it hits air. For those PC boards that have been sitting
around in that ziploc bag for several years, you may not be able to see it,
but all those copper bits are covered with a thin layer of tarnish. Solder
will not wet tarnish.

Now, flux will deal with a little bit of tarnish, that's what it's for, but
a lot needs to be cleaned. Get yourself some Scotch Brite(tm) and get to
work!

You can (and probably should--I do) buy flux core solder, but it is often
handy to have extra flux lying around, so get yourself a bottle of liquid
flux. As Mr. Crowell says, only use rosin flux (acid flux corrodes a lot
faster) but remember that you should clean the flux off once you're done.
If you've ever read that you can't carry melted solder on a soldering iron
because it won't work, the reason it won't work is that the flux in the
solder boils off. Applying flux directly to the work piece makes that
technique work. (It's how surface-mount stuff is done with an iron.)

As far as getting it hot, well, that's where the iron comes in. The kind
of iron you want depends on the kind of soldering you're doing. Putting
together some kits? Get yourself a temperature controlled iron and set the
temperature to whatever the solder manufacturer recommends. You don't want
it too hot because the adhesive that holds the traces to the board can melt
and traces can lift and nobody wants that. I've heard good things about
the Hakko FX-888D, and it's under $100 from Amazon. While you're at it, get
some liquid flux and one of those hand desoldering pumps. Get too much
solder on the joint? (And you will!) You can heat the joint and suck
the excess away. They're cheap. You might also want to get some
desoldering braid. I don't use it, myself, but some people like it.

If you want to do surface mount, you'll need a setup that's different. I
know guys who do reflow soldering with toaster ovens or hotplates and
embossing guns, but I have an Aoyue 968. I solder with the iron and 
desolder

All,

Hand soldering is very much an art form. I was pretty good at it, but 
have been learning over the years. I have learned a lot from Brian, 
KF4VOO as well as watching NASA training videos on YouTube and from 
other sources. These topics I’ve discussed on the air, but putting 
them in writing for the rest of the class .


Let me give these out as a series of points:
1. Use Eutectic solder - 63/37. That’s 63% tin and 37%lead. Eutectic 
means that both components melt/freeze at the same temperature. This 
is extremely important for hand-soldering. 60/40 is easier to 
manufacture, but gives poorer results because it was also designed for 
flow soldering. None of that lead-free crap. My XYL, Dasha is an 
environmental engineer (and a licensed Professional Engineer in the 
State of TEXAS). She’s not worried about lead contamination from our 
soldering leaching into the ground water and killing kittens and 
puppies and that’s good enough for me.


2. The flux should be rosin core. Period.

3. The diameter should be skinny. 0.46mm - the reason is that we don’t 
want too much solder in the joint.


And for today’s topic: Flux.

In an ideal solder joint, there should just be the proper fillet of 
solder where the junction is formed. Those of you who are welders 
understand fillets.


The amount of flux inside even the best solder tends to cause the 
operator to apply too much solder to the joint. The internal flux 
dissipates before the heat-bridge gets the solder flowed.


The answer - add flux to the joint. I suggest liquid flux where the 
rosin is dissolved in alcohol.


I got some good flux from Fry’s and picked up a Weller squeeze bottle 
with a needle in it. This dispenser SUCKS. Flux all over the work and 
the bench. A waste of money and time in cleaning. Liquid flux is 
sticky until completely dried out.


The solution to the problem with the SOLUTION was to get a really good 
bottle+cap+dispensing needle. I found a deal on Amazon linked here:


https://www.amazon.com/gp/product/B01G2QZQG8/ref=oh_aui_detailpage_o00_s00?ie=UTF8=1

This kit is for “Vape” - whatever that is. It’s an inexpensive kit of 
various bottles and dispensing needles. The needles are for syringes, 
but not for the pokey kind - just a blunt tip.


In the bottle with yellow cap and yellow needle is the flux. It’s all 
happy and drips out just the right amount. The black is even finer and 
filled with lubricating oil for my guns. I’ll use the other bottles 
and sizes for various glues and such.


Here’s a link to the flux I got at Fry’s, but available on Amazon:

https://www.amazon.com/MG-Chemicals-8351-125ML-Halogen-Bottle/dp/B00S16UAGE/ref=sr_1_4?s=industrial=UTF8=1471028240=1-4=liquid+flux

Just a drop or 2 makes a big difference. Keeping 100 drops OFF the 
bench makes it funner.

sophisticated, their solutions will, too.


If you want a high-level takeway from this, it should be this: Don't 
ever consider using an Arduino (or a CANMIC) on an Ethernet network.  
Use an ARM based board (like the "CHIP" or the Raspberry PI or the

to reduce common mode sneak currents on the coax
shield's outer surface.
3) Unless you plan to use 12M., you may want to not
wire this band in as it does somewhat impair the 10M.
performance due to the closeness of the bands.

I could have, would have, halved my time learning CW if I had read

CW the hard way. Learning to decode every letter into dit and dah at 5

to learn. No wonder I avoided CW operation for 30 years.


Learning to HEAR the sound of letters and numbers sent by CW at 20 
wpm, bypasses the wrong way it was taught. Learning CW by first 
listening to good CW is critical to learning the proper sounds of 
letters and words. There are several apps, such as CWtext, Learning 
CW, and Morse words, which make it easy to learn. This book provides a 
really good set of rules on how to learn the code efficiently and 
enjoying it.


If I can start learning CW again at 70 years of age, you can too. It 
is a lot of fun when you bypass the miserable dit and dah stage, and 
start recognizing the sounds of letters and words.

   Measure the actual under load (100 W. CW) voltage
at the back of the FT-920.  Faulty inline fuse holders
or connectors, and wiring losses can cost you 1/2 v. or
more.  You need a full 13.5 to 13.8 VDC at the back.
Since power to a R Ohm load is V*V/R, a relative power

You need to measure the voltage as I indicated with the rig in CW mode into 
an antenna or whatever you used before when you measured the power output.  
Now a cheap but accurate digital volt-ohm meter will cost as little as $10. 
A small investment in your hobby I think.

Re: [BVARC] Need Concrete/Hole, update...

2017-04-14 Thread Gary Sitton via BVARC

Update:

   Finally US towers gave me the specs. for their
MAB base with a MAF fold-over kit.  From the specs,
it's a 2.5' x 2.5' x 3.5' block of concrete which is
22 cu. ft. or ~3,000 lbs.  The fold over and guy-less
support requirement for the ALM-31 makes the base
that massive which is OK.  I've decided to use a local
concrete contractor to pour the premixed concrete
into the hole with a #3 rebar grid set and a form for
four, 2' x 3/4" galvanized anchor bolts at the ready.

If mixing materials by hand from bulk, the old 1,2,3 rule works well to
give 3000 psi or greater. using one bucket or container of portland cement
to 2 containers of sand to 3 containers of coarse aggregate. Of course if
you need air entrainment or want to use a water reducing, set retarding

Carefully check the sack yield.

Normal weight concrete is roughly 145 lbs/cu ft.

Use greater than 3000 psi strength concrete.

Do not add excess water. Rod the stiff mix into place.

Note the 2 x 2 x 2 should be measured at least 6 inches below grade and so
all surfaces are against firm to stiff soil.

That means you will need extra concrete to finish above grade.

[BVARC] Need Concrete/Hole work done for a light Tower Base??

The ALM-31 is very similar to their older 40' crank-up MA-40 model.  
It's made of extruded Aluminum sections rather than tubing.

Gary,  I think I would ask the tower company for engineering specs.  
Now you mention a tilt over base/ginpole.   Not gonna happen in a 2

other than a brief description in that they just started producing 
after Dayton 2016.  No manual, no drawings, no detailed specs to 
speak of.


Question to consider:  When it is extended at 31 feet and you have 
your 45 pounds of rotor and antenna (windload area not known) waving 
in a brisk, pre-wx-front breeze...what forces will be exerted 31 feet

Normal weight concrete is about 145 lb per cu.ft. That is wet

will be less than one cu.ft. Straight sack concrete is generally
easier than using flyash if you are creating at home.

If mixing materials by hand from bulk, the old 1,2,3 rule works
well to give 3000 psi or greater. using one bucket or container
of portland cement to 2 containers of sand to 3 containers of
coarse aggregate. Of course if you need air entrainment or want
to use a water reducing, set retarding admixture or super
plasticizer you are better off using redi-mix concrete and
ordering it. Air entrainment is not necessary in this climate if
the bulk of concrete is in the ground.

Carefully check the sack yield.

Normal weight concrete is roughly 145 lbs/cu ft.

Use greater than 3000 psi strength concrete.

Do not add excess water. Rod the stiff mix into place.

Note the 2 x 2 x 2 should be measured at least 6 inches below
grade and so all surfaces are against firm to stiff soil.

That means you will need extra concrete to finish above grade.

yet,  but it's extruded 6061-T6 Alum. and will weigh

need or want to fold it over fully extended! My

Arrays.   He, a Penn State prof, has gotten some very nice flat SWR

at the current art 80 and 40 wide banding techniques, including the 
Bazooka.


_http://www.k3lr.com/Dayton/Dayton2016/wa3fet.pdf_

These wide banding techniques are what is taking over the world in 
Yagi-Uda design/implementation.  See another Dayton presentation (same 
K3LR Dayton page)  by Justin Johnson, G0KSC.Wide banding, low 
noise and direct matching all at a cost of slightly reduce 
parasitic gain, and slightly reduced F/B, but an increase in antenna 
system efficiency due to the lack of the lossy matching network (i.e. 
Gamma, T, Hairpin, etc.).   This technique has been stareing us in the 
face out of the ARRL Antenna Handbook since the 50's and only Mosley 
took advantage of it back then, but never pushed the details of its' 
advantages...IMHO.


Another way to broad band an 80 meter dipole is to utilize a Tornado 
Loading/matching coil.   K3LR highlighted this in his 2017 Greater 
Houston Hamfest K3LR Multi-Multi talk.   Read about it in the BVARC

on 80 CW. I decided to just go for the inverted vee with the
center at 50 ft., and it sure has worked the DX. The legs are
running North-South. My last 5 80M QSO’s were with A25UK, 5V7P,

I was having problems with my galvanized stranded wire usually
used for marine antennas as it started to rust and I was
extremely hesitant to touch it even with gloves, after less than
2 years.

I found a great product from Davis RF called Flex-weave. It is a
polyethylene coated #14 wire made of 168 strands of #36 wire. It
is a very tough coating and is very flexible and resilient.

detected any deterioration of any sort and it doesn’t stretch nor

I probably would have done the same at a $50 price difference (I paid less

I have to say, though, the Chinese manufacturers don't makeup those names.
Radio marketing companies do.  You and I could get together and make a deal
with Qixiang to market that same radio under any name we invented.  If it's
a good value and we know how to distribute, we'll make a mint!

AnyTone <http://www.wouxun.us/item.php?item_id=295> is the brand used in
the Americas.  Powerwerx sells the same radio as the Powerwerx DB-750X
<https://powerwerx.com/db750x-dual-band-commercial-mobile-radio> (have one
permanently mounted in my car); in France it's the CRT-270M
<http://www.gotechnique.com/postes-vhf-uhf/793-crt-270-m-bibande-vhf-uhf-mobile.html>;
in Italy it's the Polmar DB-50M
<http://polmar-radio.com/en/prodotti/radioham/db-50m-2/>; in eastern and
western Europe it's the Intek HR-2040
<http://www.intek-radios.com/?C=Product_H.php=343>.  These are good
value radios, tried and tested, all over the world.

Most on this list are old enough to remember the 70s and 80s when we called
Honda, Datsun (Nissan), Subaru, etc., "Jap Crap".  I remember when Yaesu
and Kenwood were called Jap Crap.  Some of the same old farts now refer to
Wouxun and AnyTone as Chinese Crap radios, and talk about "jap crap" like
it was made in America.  Thing is, some of these Chinese companies have
been making and selling commercial radios since the late 80s, early 90s
(25yrs?!).  Cracks me up.

BTW, BaoFeng just released news
<https://anytonetech.com/baofeng-tech-launches-our-sister-brand-anytone-tech>
that it has partnered with Qixiang to form a partnership named AnyTone
Tech.  BaoFeng sells Walmart Chinese crap to the low-end market.  This will
be a game changer.

For many of us, it's all about "bang for the buck" - we do the research and
buy what makes economic sense for our own situation (Elecraft makes a fine
radio, but as much as I'd like to buy "made in the US," my ICOM 718 does a
fine job at less than one-fourth the price).  Maybe, someday, I'll feel
like splurging on that Elecraft K3.

I have a feeling you'll like the KW, and congrats for doing the
research.  I probably would have done the same at a $50 price
difference (I paid less than $150 for my almost new 5888UV - it
was a "no-brainer").

I have to say, though, the Chinese manufacturers don't makeup
those names.  Radio marketing companies do.  You and I could get
together and make a deal with Qixiang to market that same radio
under any name we invented.  If it's a good value and we know how
to distribute, we'll make a mint!

AnyTone <http://www.wouxun.us/item.php?item_id=295> is the brand
used in the Americas.  Powerwerx sells the same radio as the
Powerwerx DB-750X
<https://powerwerx.com/db750x-dual-band-commercial-mobile-radio>
(have one permanently mounted in my car); in France it's the
CRT-270M

<http://www.gotechnique.com/postes-vhf-uhf/793-crt-270-m-bibande-vhf-uhf-mobile.html>;
in Italy it's the Polmar DB-50M
<http://polmar-radio.com/en/prodotti/radioham/db-50m-2/>; in
eastern and western Europe it's the Intek HR-2040
<http://www.intek-radios.com/?C=Product_H.php=343>.  These are
good value radios, tried and tested, all over the world.

Most on this list are old enough to remember the 70s and 80s when
we called Honda, Datsun (Nissan), Subaru, etc., "Jap Crap".  I
remember when Yaesu and Kenwood were called Jap Crap.  Some of
the same old farts now refer to Wouxun and AnyTone as Chinese
Crap radios, and talk about "jap crap" like it was made in
America. Thing is, some of these Chinese companies have been
making and selling commercial radios since the late 80s, early
90s (25yrs?!).  Cracks me up.

BTW, BaoFeng just released news

<https://anytonetech.com/baofeng-tech-launches-our-sister-brand-anytone-tech>
that it has partnered with Qixiang to form a partnership named
AnyTone Tech.  BaoFeng sells Walmart Chinese crap to the low-end
market.  This will be a game changer.

For many of us, it's all about "bang for the buck" - we do the
research and buy what makes economic sense for our own situation
(Elecraft makes a fine radio, but as much as I'd like to buy
"made in the US," my ICOM 718 does a fine job at less than
one-fourth the price).  Maybe, someday, I'll feel like splurging
on that Elecraft K3.

Gary,
  Except for the business of spending more on the antenna system than 
the rig ( not ), I think that you made some wise choices.
There is good reason to get an AX.25- ready & dual band rig ( eg. APRS 
possible ) to be 'better' equipped.
Let me know if you need an A/B coax grounding switch or *good used 
PL-259s. I should be getting these out of my 'laundry-size' bins tonight.
I need to dig through my TM-D700a supplies for that mini-din data 
connector which is also spare. Unlike the extra as-is microphone, I 
did see it lately.
*What is a good used PL-259? The one with the coax insulator that can 
take high soldering heat without drooping, and has already been used 
in a good installation that just needed to be extended- or cut off for 
a different connector eg. mini-UHF. I am not necessarily including the 
really old ones that had bakelite insulation, usually olive-drab in color.

Guys, thanks to all for the advice. I've decided to get a Kenwood 
TM-V71A & an Arrow GP 146/440 2m/70cm ground plane. I also obtained 
some Wilson 400 low loss coax to feed it. This blew my budget of $200, 
but I liked the reviews and features of the KW rig compared to the 2m. 
mono banders. The GP antenna was only $50 new and looks very sturdy. 
Also is attached a photo of the stanchion for my crank up hex beam 
mast mounted on the nearly cured, 3,000 lb. concrete base. "In for a

For the 146.94 Repeater:
Offset is negative, 600 Khz.
That means you listen ( receive ) on 146.94 Mhz.
That also means that when you transmit, your rig will need to display 
146.34 Mhz. yet that would not key the repeater.
In order to do that, you will need to set your transmit subaudible tone to 
167.9 Hz.

So you need to first:
Familiarize yourself with all of the buttons ( the manual will tell you 
about them, look back and forth at the radio while looking at the manual 
descriptions- many buttons will have dependancies- as in press the 
'function' button then press a different one within a certain short period 
of time.

Read the sections on:
Setting up the radio frequencies
Saving those frequencies to memory
ARS- Automatic Repeater Shift ( this may should save you time in the long run )
Offset- The standard 600 Khz ( .6 Mhz ) offset may already be set, but you 
should confirm how you manually could select + or - offsets.

Subaudible Tone.
As you read the pages above, you may want to write down what page in the 
manual you found them on for later reference in programming other repeaters.
When you manage to get the first contact made over the repeater, that would 
be a good time to stop and ensure that your settings are saved to a memory 
file in the radio for channel 1.
As soon as that is accomplished, you may want to see if you can read the 
radio with a programming cable and save that base program to a file. If you 
are better with a PC than the radio buttons- you may be able to add 
channels more quickly with the PC.

I didn't dodge the Chinese rig because of the brand name, but the reviews, 
and convenient warranty and repair. I recently bought a Chinese digital 
scope because of its price, features and reviews. The rig is due via UPS 
today and all I need now is some help setting up the 2 m. repeater 
operation all of which is a mystery to me.

I have a feeling you'll like the KW, and congrats for doing the research. I 
probably would have done the same at a $50 price difference (I paid less 
than $150 for my almost new 5888UV - it was a "no-brainer").


I have to say, though, the Chinese manufacturers don't makeup those names. 
Radio marketing companies do. You and I could get together and make a deal 
with Qixiang to market that same radio under any name we invented. If it's 
a good value and we know how to distribute, we'll make a mint!


AnyTone is the brand used in the Americas. Powerwerx sells the same radio 
as the Powerwerx DB-750X (have one permanently mounted in my car); in 
France it's the CRT-270M ; in Italy it's the Polmar DB-50M ; in eastern and 
western Europe it's the Intek HR-2040 . These are good value radios, tried 
and tested, all over the world.


Most on this list are old enough to remember the 70s and 80s when we called 
Honda, Datsun (Nissan), Subaru, etc., "Jap Crap". I remember when Yaesu and 
Kenwood were called Jap Crap. Some of the same old farts now refer to 
Wouxun and AnyTone as Chinese Crap radios, and talk about "jap crap" like 
it was made in America. Thing is, some of these Chinese companies have been 
making and selling commercial radios since the late 80s, early 90s 
(25yrs?!). Cracks me up.


BTW, BaoFeng just released news that it has partnered with Qixiang to form 
a partnership named AnyTone Tech. BaoFeng sells Walmart Chinese crap to the 
low-end market. This will be a game changer.


For many of us, it's all about "bang for the buck" - we do the research and 
buy what makes economic sense for our own situation (Elecraft makes a fine 
radio, but as much as I'd like to buy "made in the US," my ICOM 718 does a 
fine job at less than one-fourth the price). Maybe, someday, I'll feel like 
splurging on that Elecraft K3.

Re: [BVARC] FW: EMERGENCY: X-Class Solar Flare with CME

2017-09-06 Thread Gary Sitton via BVARC

OK guys, a few facts here:

   1) EM radiation (visible light, IR, UV, X/Gamma rays) from
    the Sun travel at the speed of light at c = 186,000 miles/sec.,
   2) CME are plasma masses which move much slower
    at most 1000 miles/sec. which is slower than c, and
   3) 48 hours would correspond to a CME moving at about
    500 miles/sec. to cover 96,000,000 miles.

In any case, let's hope/pray that this killer CME misses us
in two days!

2 hours ago, we had an X-class solar flare above 10. It was
followed by a large Coronal Mass Ejection.

While it is still being modeled, it will impact earth within 48
hours.

Likely effects:

1. Large-scale power grid disruption on the sun-facing side of
the earth during impact

2. Large-scale disruption of communications:

A. HF Radio blackout

B. Satellite blackout

C. Data/Cellular loss of information

D. Damage to computer systems

3. Earthquakes during compression of the earth’s magnetopause.

Present focus is on Harvey and Irma and the attention of the

Gayle:

 I assume you mean 200-300 watts which is not
a significant upgrade from 100 watts.  Also consider
linears with 120 VAC requirements not 240 VAC like
some of the big PAs.  A used AL-80B for ~$1,000 is
a good choice.  Keep away for Heath Kit SB-200 and
220 PAs as they would need some repairs and/or
update mods.  The tube rigs with 3-500 triodes are
nice since that tube is rugged and fairly cheap,

2018-01-18 Thread Gary Sitton via BVARC


    I accidentally touched the PF1 key when I turned

my 2 Mtr. FM rig on today (TV-71A) .  This selected the

WX channels (162.xxx MHz) and I can't get it to change

back to the 144 MHz band.  The [F], [BAND SEL] sequence

does not seem to work??  My rig is useless for now and

all I can get is the WX reports.

Is it a TM-V71A?  Have you tried just hitting the PF1 key again.  This is 
the way my TH-D210A works.




Also, I can go back to memory mode to get out of WX mode.



Have you read the manual?

[BVARC] Hunting rifle FOR SALE.

2018-08-28 Thread Gary Sitton via BVARC

Hi:

    I have a lightly used (barely broken in) Remington 700

0.270 top loader (4) rifle with a synthetic stock for $600

or "best offer".  Consistent 2 MOA groups with factory

loads.  In this nice package is also included:


1) Large cloth carrying case and Limbsaver butt pad,

2) Nikon BuckMasters 4-12x40mm scope (BDC reticle),

3) Briley tapered mussel brake and custom 3 lb. trigger,

4) Other miscellaneous goodies.


   The scope has been sited in @ 100 yds. and is ready to

go.   I also will include the original Remington 700 trigger

with a 5 lb. pull.  I'm selling this rifle because I wanted to

use it for long distance target shooting but the 0.270

recoil was a bit much for my old shoulders, Hi.


Thanks & 73,

Re: [BVARC] QST, Kenwood TV-71A programming help needed.

2018-01-18 Thread Gary Sitton via BVARC

That's the trick, MR!  BTW this was not mentioned
on p. 66 of the TV-71A manual.  There it only tells
one how to get the WX channels, but not to unget
them. To call Kenwood 's documentation "manuals"
is a real stretch.  They are more a semi-ordered set
of semi-accurate examples of using the radio's various
buttons.  I had a TS-590S and loved the radio, but the
manual was obtuse, sometimes wrong and generally
a real pain.

[BVARC] 24" LCD monitor available.

All:

    I have a color LCD monitor in good condition

which is available to anyone who will pick it up from

my QTH in the Heights (77008 just inside Loop 610

North off  West 21st St.  near Yale).  I'm willing to give

it away, but a nice item in trade would help too.

   It is an older Gateway LCD monitor (fluorescent

back lighted, model LP2424) with an HDMI , a  DVI,

and a VGA port.  Screen size is 24" diagonal with a

16:10 aspect ratio with a nice maximum resolution

of 1920 x 1200 @ 60 Hz. This would make a very nice

PC monitor for someone.

I can trade you equivalent (or a mix of)   #18, #20 and many smaller gauges

Looking for about 50 feet at a minimum and could use 75' to 100' if you

  The wire idea might just work and two 17 AWG = one 14 AWG equivalent.  
Also, I will be doing the left knee in a few more months and I am at 118° 
bend now!  I am having a surprising amount of ankle and foot pain along 
with the knee, etc.

Rick, consider 17 Gage electric fence wire available at your local feed 
store.  I think I bought  1/4 mile for something under $20.  Try two 
strands, hold one pair end  in a vice and twist the other end of the pair 
with an electric drill.  It completely changes the feel of the wire.

So building a wire antenna huh? You know that not only is enameled wire

volunteer tube testing to the members of the club.


This is the procedure --

First, contact me at john.mechura at gmail.com with your list of tubes to 
be checked so I can see if they are listed in the chart.  This machine will 
check tubes from Octal to Nuvistor, basically consumer-type tubes.


I can meet you at the Saturday breakfast shindig to test your tubes.

Caution! when removing or handling tubes, the numbers can sometimes come

Re: [BVARC] Need antenna build advice

The J pole I got gave the closest feed impedance to 50 Ohms (@ 146 MHz) 
when the four radials were exactly perpendicular to the radiator. When 
testing any antenna, keep conductive objects at least a wave length or more 
away from the radiator.

I don't think there's a difference between one conductor and another except 
for a slight difference in efficiency.  The problem with a JPole is that 
there are three separate bits that can need adjustment (the length of the 
radiator, the length of the quarter-wave stub, and the position of the 
feedpoint on that stub) and if you don't adjust the right one, you'll get 
poor results.

Ralph:
No, any reasonably conductive metal will have a free space
velocity factor of 1.0.  However, putting conductive objects
very near to a metal wire or tube or rod will change this.
Also, any insulation on a wire will reduce the velocity factor.
I just bought a nanoVNA-F vector network analyzer for
$100 which will sort all of these tuning issues out quickly.
Sorry about the quarantine or I'd get you a hand with
this, but I'm hunkered down for the next few weeks here.
Does there seem to be a low SWR point somewhere near
to your operating frequency.  The minimum SWR point
and the resonant frequency are generally not the same
but should be close enough for rough tuning purposes.
