[BVARC] Fwd: Please publicize Free, Zoom Technician Licensing Course starting Sept 7

[Gus Bernard via BVARC]

See below, from Rol Anders.  I took his last Extra Course, and it was
pretty good - convenient and thorough.  Once you register, you get access
to materials and recordings on his Google Drive (if you miss a class, you
can watch a recording).  They do a live Tech, General and Extra every year.

However, FYI as stated in an earlier thread, I thought Gary W4EEY and
Dave's YouTube course was better, and more convenient if you can't do the
live Zoom.  https://w4eey.com/ham-license-classes.html.  They have
seriously improved their format and presentation over the last few years.
Each class is a separate YouTube video, and materials are in a Dropbox
folder.  (BTW, they also do a live Tech, General and Extra Zoom
version every year.)

The main difference between the two is in the manner of organization and
presentation, and you may like one over the other.  I think Gary's is much
a more modern, polished and professional presentation (and therefore more
effective).  Of course, taking either live Zoom course allows you to
participate live and ask questions during the class.

If you take W4EEY's most recent course AND do HamtestOnline.com at the same
time, you can skip buying the ARRL exam book (or save a bunch and
buy/borrow an older version from a friend).  (HamtestOnline is much better
than reading the ARRL book, but you won't have a bookshelf reference if
that's important to you.)

Re: [BVARC] High power EFHW Antenna/ MFJ-1982HP

[Gus Bernard via BVARC]

BTW, for antenna wire, see articles by our own Rick Hiller in the technical
section at www.bvarc.org . I think he's addressed this subject.  I like #14
or #12 insulated.  Solid or stranded choice depends on your strength and
flexibility requirements. Thicker wire gives a slightly better bandwidth at
the cost of weight.

Re: [BVARC] High power EFHW Antenna/ MFJ-1982HP

[Gus Bernard via BVARC]

See product design specs, as well as articles, at Balun Designs.Com. use
the core mix type for the bands you'll operate on.  For high power,
double-up on size 240 cores.  Youtube "TRX Bench" channel has a great
4-part video series on building baluns.

My experience tells me that if I want a long lasting, reliable balun (good
quality components and workmanship that withstand the elements), it's more
cost effective to buy off the shelf from Balun Designs or equivalent. (The
amount I saved wasn't worth the trouble.)  Of course, making my own is fun
and educational; but I now buy my baluns from Bob.

I second John's recommendation about W4EEY's YouTube channel, if you're
looking for a course. I've taken a few, and his extra class is the best
around - and free.

Thanks Chris, turns out I had them bookmarked from a previous search.

Hi, all:

Can someone please recommend a (online) source for quality replacement
batteries for EF Johnson and Motorola commercial handheld radios?

Does anyone have an opinion about CutRateBatteries (available through

John, ARS stations will monitor the published DOD frequencies at the stated
times.  At those times, DOD stations will announce the specific ARS
frequencies to be used.  60m will probably be used if available, but other
frequencies can also be used.

Well, that's the way I understand it.

Re: [BVARC] The US Airforce may have shot down an Amateur Radio Pico Balloon over Canada

[Gus Bernard via BVARC]

LOVE IT!

BTW, the Naval Academy's midshipmen balloon experiment site (linked under
the pico balloon picture) is extremely interesting.  I'm not a "ballooner,"
but that site piqued my interest!

Re: [BVARC] Great coax info for the neophyte (and experienced) members of the club.

[Gus Bernard via BVARC]

To piggyback on Rick's recommendation:

Jim Brown K9YC is an audio expert and prolific writer.  I highly recommend
scouring the web for ANY and ALL articles by him, most of which are linked
at his website .  He has also written for the
ARRL Handbook and Antenna Book.

His articles on bonding and grounding, RFI, and USB audio interfacing have
been very helpful to me.  73,

Re: [BVARC] noise eliminating headset/microphone for HT

[Gus Bernard via BVARC]

Sheree, I recommend against a headset that blocks what's going on around
you.  Instead, I recommend (and have had great performance from) an
in-the-ear piece. You can connect it to the radio, or to an external
(speaker, etc.) mic.  This way you can hear the radio perfectly, as well as
everything that's going on around you..

Here's the one I use:
https://www.amazon.com/gp/product/B01M9C31OR/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

The only trick is to determine the best size of earpiece - they come small,
medium, large.  Some headsets include just one pair, others come with one
of each.

Re: [BVARC] ethernet question

[Gus Bernard via BVARC]

JP,

If the system worked when you bypassed the switch (using the same cables),
then the cables are fine.  Before trashing the switch, try moving the cable
to a different port on the switch.  Sometimes, an individual port will go
bad; and if you find a bad port, try cleaning the contacts with a contact
cleaner.

Brian,

Shielding a cable works if the socket/jack of the device it is connected to
is also grounded (on at least one end of the cable).  However, in some
configurations, you might need to worry about ground loops if the
socket/jack of devices on both ends of the cable are BOTH grounded BUT NOT
to the same ground potential.

This could especially be a problem with USB cables between computer and
radio.  For EMI issues, sometimes it's better to use toroidal or clamp-on
ferrite chokes at both ends, instead.  I had a problem with my IC7200 that
was solved only after wrapping both ends of the cable 3 times around Mix 31
clamp-on chokes.  In very bad cases of interference (like RF in the shack),
a USB isolator might be needed.

Re: [BVARC] need source for N-type female bulkhead connectors with hardware

[Gus Bernard via BVARC]

You might also contact Richard East, my main supplier of RF connectors,
coax strippers and crimp tools - you've probably met him or seen his table
at various area Hamfests.  He carries Amphenol, and a good quality less
expensive brand called RF Industries (RFParts also carries this brand).

Richard is a great guy - friendly, knowledgeable and helpful, and always
throws in a little lagniappe with each order.  He has an eBay store
(N5IAW), which does not list the huge amount of stuff he carries.

But not to worry - simply email him (richard or n5iaw @navcomusa.com) and
tell him what you need.  You can PayPal him and he'll ship quickly from
Mississippi.

Re: [BVARC] Looking for a Mosfet

2d BTW, they don't tell you on the original checkout page, but Mouser has
an economy USPS ($3.49) shipping option if you're not in a hurry (but it's
usually 2-3 days because they're in the Dallas area):

While checking out, select a shipping option, then "Continue Checkout."
There, (Payment Options, I think) look around/scroll on the page for the
economy option.  Ask if you can't find it.

call customer service and they'll quickly put a Tech on.  Tell the the Tech
what you're looking for, and they'll find it or offer a replacement that
will work for you.

Re: [BVARC] Fixing a stripped aluminum screw hole

[Gus Bernard via BVARC]

Mark, for such a small screw, I'd try the blue LokTite (or equivalent) and,
if it doesn't work, drill and tap for a larger screw.

Don't know what it looks like under the lid, but another alternative might
be to hold it closed from the inside with Velcro or VHB tape.

Re: [BVARC] Looking for parts to build a Balun

[Gus Bernard via BVARC]

I try to buy locally, if possible, but except for the tape the items you're
looking for are not easy to find locally.  I always buy electronics parts
from Mouser (here in TX), but some like DigiKey, etc.

1.)  DO NOT buy "no-name" toroids for baluns/ununs. Search Mouser or
DigiKey for the brands they carry, and buy one of those, or get them from
Palomar Engineers or an equivalent.  I like the Fair-rite brand and buy
them from Mouser; Palomar carries a competing brand.

2.)  You don't "need" glass cloth for a balun, but the 27 can be found at
most any electrical supply house that carries the 3M line - locally, I like
ACE Electronics or Grainger.

3.)  There are LOTS of places to get PTFE wire.  I doubt EPO has it, better
chance at ACE, but call both and ask.  Otherwise, search online.  I buy my
enamelled wire from eBay - they actually have a few good sources for it.
The Wireman is a good source of antenna wire, generally.

When shopping for most component parts specific to ham radio, I usually
start at R&L Electronics and/or DXEngineering.  They're reputable,
reliable, good quality and great customer service.

Good luck,

Gus, K5GMB

[BVARC] Fwd: [TexasRACES] DOD COMEX 22-2

[Gus Bernard via BVARC]

ALL:

DOD COMEX 22-2 is now underway. Monitor WWV at 10" past the hour, and
please see the forwarded message below from C. Matthew Curtin KD8TTE.

If you are at all interested in emergency communications or operating HF on
60 meters, this is an important practice event.  Matthew has a great
YouTube video that explains how this works!  See the link in his email,
below.

Hope to hear you on 60m this week!  73.

To: 


All:



Are you planning DOD COMEX 22-2 participation in your area? I've asked the
"emergency communications" operators and have found shockingly little
engagement. Any HF-capable amateur operator should be able to participate
on at least some level, but there seem to be lots of assumptions about.



"I'm not in MARS." [This part isn't for MARS, it's for you.]



"I don't have 60m." [Are you sure? Even if you really can't, there are
options.]



"It's over my head." [It's just voice. Have you actually looked at what it
takes?]



I made a video to try to encourage amateur participation, and have an
accompanying station plan that helps to make sure you get the critical
tasks done day by day, and even to coordinate with others so you can work
as a team in case one operator can't cover all of the different things to
do.



Interoperability is a critical capability and I'm growing concerned that
lack of engagement by the amateur "emergency communications" crowd will
feed the argument that the amateur radio community simply isn't up to the
demands of operating post-disaster or emergency in a meaningful and
coordinated way.



I hope the video and accompanying plan template encourage participation.
Please share it if you think it will. I have no inside information here
(I'm not a MARS operator) but I'm happy to answer any question I can. I did
attend the briefing (linked from my video's description) and have a fair
bit of experience in cross-service exercises on 60m.

Re: [BVARC] RFI

[Gus Bernard via BVARC]

I don't understand what is "RFI on occasion into my PC . . . by apparently
disconnecting the com port from Commander," but:

1.  By transmitting into attic and gutter antennas, you're lighting up the
whole house and shack with RF;

2.  As already stated, add snap on ferrite cores of the correct mix to DC
power cords and both ends of USB cables. The cores must be large enough to
hold at least 3 wraps (loops) of cable, and maybe more (depending on the
amount of RFI);

3.  Ground all pieces of equipment (including antenna switches AND your
computer) to your shack's station ground in a "home run" fashion; and

4.  If #s 1-3 don't solve, reduce TX power until problem goes away.

I second Robert's choke suggestion, and it may need to be a quality
isolation transformer, but you don't give enough information about your
feed line configuration for a proper recommendation.

Finally, there are USB isolation transformers available; and, you might (by
trial and error) find a computer with COM port input circuitry that is less
sensitive to RF.

Re: [BVARC] “Plastic” Mast

[Gus Bernard via BVARC]

I second what Rick says.  Be advised most readily available PVC is subject
to UV degradation and will get brittle with time.  Some PVC (like that used
in deck furniture) is UV resistant.  Fiberglass works, but will also
degrade unless it's treated or you paint it.

Re: [BVARC] lithium chemistry batteries for emergency power

[Gus Bernard via BVARC]

Ron,

There's a lot of battery-building folks out there that don't think you
really need a BMS, which is a huge part of the price of LiFePO battery that
includes it, especially as you get into bigger batteries.  I'm one of those
that decided to skip the BMS on my 200Ah DIY build (of course, my little
(20Ah) Bioenno has one built-in).

First reason is that most "affordable" Chinese BMS boards are the first
thing to go bad.  And many of those often and eventually will.  A good one
is expensive and hard to find.  You pay more for a Bioenno or Battleborn
(and several others) because of their warranty and reputation.

Second is that most of the protections you can do without, or you can find
a different, cheaper, way to implement.  For example, you really don't need
low temp protection in the Houston area; almost any smart charger can be
set to prevent an overcharge; cell balancing can be done inexpensively with
ancillary equipment; and, I wouldn't spend huge bucks on a reliable BMS
only to prevent an over-discharge (I bought some cheap programmable voltage
indicators with buzzers used in the RC/Drone hobbies).

Re: [BVARC] New HAM needs assistance tuning a Butternut HV9V Antenna

[Gus Bernard via BVARC]

Just to clarify and properly cite - the .PDF file I linked was found online
at a DXE server, but was actually published by Cushcraft/Hy-Gain (MFJ) and
written by AA5MT.


BTW, Mark, while installing/tuning your Butternut, you might be interested
in this about antioxidants:

I'm getting ready to install an R9 and called Cushcraft to ask about their
recommendations regarding the use of antioxidants during assembly/tuning.
(I specifically asked about Penetrox A or Noalox.)   Of course,
knowledgeable hams have been applying antioxidants to antenna connections
for years, but I was specifically interested in their take regarding
effects on conductivity.

The rep said the antenna should work fine without such antioxidants but
slip-joint conductivity might sometimes actually improve with the use of an
antioxidant.  He also suggested such antioxidants are a good idea near salt
water (including the Houston area).

A DXE rep told me they recommend and swear by Jet Lube SS-30 (a copper
infused grease without graphite) as a superior antioxidant to Penetrox A or
Noalox because these last 2 eventually dry-out.  This got me thinking about
the possibility of galvanic corrosion.

I keep in the shop a tub of Loctite C5-A, a very good quality competitor of
Jet Lube SS-30, which, while working in the power plant, I learned to smear
on everything needing an application of anti-seize.  This seemed like an
opportunity to save some money!  Now, the Jet Lube Technical Data Sheet
(TDS) says that SS-30 is "Not intended for use with aluminum where galvanic
corrosion could be a significant issue."  And, the Loctite C5-A TDS does
not mention aluminum either way.  The difference between C5-A and SS-30 is
that C5-A contains graphite in addition to copper.  Some would point out
that graphite attracts moisture, possibly creating an electrolyte leading
to galvanic corrosion.  On the other hand, some would point out galvanic
corrosion is nearly impossible within a grease barrier.

So, I had almost decided to use C5-A on my R9 until I remembered the
incredible mess it makes - no matter how many rags I use and how careful I
am, it gets on EVERYTHING (and all over me).  I bought the Penetrox!  (I'm
not worried about it eventually drying out because I don't think that will
affect conductivity or disassembly.)

[BVARC] Locating RFI at HF in the Neighborhood

Hi, all:

Does anyone have a loop antenna and HF receiver that I could borrow to

I have terrible constant noise nearby that's driving me crazy.  I've
already eliminated everything in the house, and maybe one of you has
already been through this before.

Re: [BVARC] RF Exposure Limits

[Gus Bernard via BVARC]

Jeff, thanks for the link to the ARRL RF Exposure page - that's what I was
looking for but didn't find.

Ron, thanks for the example!

Sure would be nice if the ARRL would advise us of how best to comply.  I
looked but haven't found anything on their website.

Re: [BVARC] Powerpole Connectors/Components for Mobile Install

[Gus Bernard via BVARC]

No, but I buy right from the Powerwerx website, which is cheaper than
buying their stuff on Amazon!  They ship fast - I just replenished my APP
parts box after the freeze and the stuff arrived in 3 days.

Beware that there are a lot of APP knockoffs out there.  I don't think EPO
sells genuine APP - call and ask.  I like, and am willing to pay for,
genuine Anderson PP products.  It's what I use for all my radio and battery
box connections.

Re: [BVARC] Inverter question

[Gus Bernard via BVARC]

BTW, the useful life of a lead acid battery charge cycle is 50% state of
charge (~12.1V).  Repeatedly discharging below this will shorten battery
life.  Discharging below ~11.6V will permanently damage a lead acid
battery.  So, even tho your batteries are probably already shot, you might
load test it only down to ~12.1V.

Re: [BVARC] Inverter question

[Gus Bernard via BVARC]

What Rick & John said.

If those 3 batteries have been sitting there since 2012, they're likely
past their end of life and no longer reliable.  A "run of the mill" marine
battery will last only 5yrs.  A cheap (Walmart) marine battery, maybe
3yrs.  I'd replace them and/or do a load test on them (with a heat gun or
hair dryer).

To operate reliably, the system you describe requires decent quality
"storage" batteries.  Even a *deep cycle* marine battery is not a good
solar system *storage* battery.  The cheapest (in the short run) reliable
solution is to use flooded lead acid golf cart or forklift batteries.  The
cheapest (in the long run) solution is LiFePO4.

For solar system storage battery info, see DIY Solar Power with Will Prowse
, or hundreds of
others on YouTube.

Re: [BVARC] Palomar Engineering End Fed and DIY Delta Loop

[Gus Bernard via BVARC]

Ron, your random wire setup appears nearly the same as mine, including all
the grounds you describe. I use a 130' Inverted L @ 25' fed by 50' of coax
though a 9:1 unun, with the shield choked at the shack end, and 3ea 125'
counterpoises (2 of which run about 22' under, and parallel to, the random
wire).

However, I tested various ground and counterpoise configurations, and my
station performs better when the counterpoises are not earth grounded.  I
do not earth-ground or choke the antenna-end unun, so that my coax acts as
a 4th counterpoise.  I think every installation's ground and counterpoise
configuration will perform differently, depending on soil conductivity,
surrounding objects, relative heights and lengths of components, and other
variables.

I suggest anyone with an end-fed wire test different ground configurations,
vis-a-vis counterpoises and earth grounds, to see which gives the best
performance for a particular location.

Your post made me think of, and I recommend, the following 3 videos by Steve
Ellington, N4LQ , which helped me quite a bit
with this issue.  He's a half-wave guy, but I think his analyses are valid
for the random wire.  The first deals with this very issue:

EFHW Grounding Compared 

The next two are related, I think.  They're very descriptive, in a
practical sense, of what's going on:

EFHW Antenna Configuration Test Results 

EFHW Installation Summary or Is your feed line part of the antenna?


I apologize for the late post, but hope the Steve Ellington videos help
those who might still be interested.  Cheers, and 73,

Gus, K5GMB

Re: [BVARC] Our email list is publicly available?!?!?!?!?

[Gus Bernard via BVARC]

Howard, I am a lawyer and can tell you there is no liability issue. Don't
know where people get that idea.

Fact is, many of us want our email addresses and phone numbers available so
that others may easily find us.  Remember WAY BACK when all of our phone
numbers were in the PHONE BOOK?  Likewise, one of the BIG benefits of a
listserv like ours is the ability to go back and keyword search the
archives for LOTS of great information.

If you don't want the rest of us to find you, you can simply advise the
webmaster and he will remove that information from the "public" roster.
It's pretty hard to participate on this listserv "email incognito" although
some of us use special email addresses for our "radio" communications.
(One way to control email addresses leaks is to compartmentalize them -
have several, each of which you use for specific and limited purposes.)

If you really want something to remain private, don't write it or type it
or email it.  If you want a phone number or social security number to stay
private, don't give it to anyone.  You wouldn't leave your wallet lying
around.

Look, ham radio is a public and social hobby.  Hams like meeting, and
learning about, each other, and learning from each other.  That's a big
reason we join CLUBS.

Either way works, Wayne, but downloading the actual application from the
Zoom website "generally" gives a more reliable experience, and with
additional features you might not get in the browser-only version.  That
said, the total experience is dictated by the power of your computer, your
browser version, and the speed and bandwidth of your internet connection.

If you download the app, you would launch it just before the meeting.
Then, click "Join" and, when prompted, simply enter the meeting ID and

Re: [BVARC] Antenna Question

[Gus Bernard via BVARC]

John,
I operate daily in the city, and more than 80% of my operations are MARS,
SHARES and CAP (HF), with the rest divided between ARES/Ham (HF & VHF/UHF)
and CAP (VHF).  I do all of this with only 2 antennas:  A dual-band Comet
GP-6 at 35', and a home-made 130' end-fed inverted L random wire at 25'
(fed through a good tuner and 9:1 unun).

With the GP-6, I reliably hit repeaters as far away as 40-45 miles (i.e.,
Splendora, Richmond, depending on height of the repeater antenna).

With the wire, I reliably (most days) cover a radius of 350-650 miles
(i.e., Slidell, LA, Gage, OK, Carlsbad, NM).  Properly setup for NVIS, you
should be able to hit most of TX (except maybe far west TX (I can't hear El
Paso)) with a random wire.  HF DX is rare at my station, though (during a
contest/exercise) I had a few QSOs with Canadian military stations, and one
with a Peruvian military station.

Some hams have several HF antennas, sometimes one for each band they like
to operate on.  I prefer a compromise antenna (like the end fed wire) that
will work most bands with a tuner.  If you're interested in longer
distance, you might add a 3rd antenna - a vertical.  I'm currently
installing a used Cushcraft R9 at 35'.

Hope this answers your question.

Gus, KG5OFB

Most of the notes & drawings from his videos are posted to his Dropbox for
viewer access.

BTW, Rick - you may not be an engineer with a classic Porsche (birthday
present), but we look forward to The Radio Hotel every month with baited

Re: [BVARC] Heath Kit History

[Gus Bernard via BVARC]

Here's a fun Ham Nation YouTube video about Heathkit's history and a
Heathkit obsessed ham, Dave W7UUU, who does some incredible Heathkit
restorations and projects:

Re: [BVARC] Microphone

[Gus Bernard via BVARC]

I have 3 Astatic D-104 mics, which I bought eBay cheap to rebuild and adapt
for use on my "modern" radios.  I finished one of them (original, no preamp
UG8 base), which I used as my everyday mic until last week.  I gutted the
whole thing, rebuilt the head using a "better than Heil" CUI electret
element resting in a foam bed (basically, mimicking Heil's D-104 conversion
kit), and rewired the base using Heilwire.  It works nicely on all 3 of my
ICOM rigs (718, 7200, 7300).

It was a fun project, and I have lots of info to share if anyone has
questions.

Re: [BVARC] Recommendation for 2m/70cm Vehicle Mag Mount

[Gus Bernard via BVARC]

One of the best deals I've ever seen (or owned) for a dual band mag mount
is the MFJ-1728B .  It's a
little long, but it also does 6m.  Comes with a BNC adapter for your HT,
and NMO mounts to the base.  I purchased a separate ground plane "kit"

so I can use mine both on a vehicle or on a mast.

[BVARC] Fwd: [NewHams] RF Connectors / test equipment connectors from WA1MBA

[Gus Bernard via BVARC]

See link below frm Dan Marler @ newhams groups.io.

BTW, for some time I've been converting all connectors in my shack (&
portable gear) to Type N:  With the exception of panel connectors on the
back of purchased gear, all antenna switches, coax, baluns, ununs,
lightning protection and other gear and accessories are purchased with Type
N installed.  This involves purchasing or making a collection of adapters
and jumper cables.

The project started because I often needed to make jumpers to interface my
own ham accessories (antennas, switches, feedline, etc.) to my issued Civil
Air Patrol radios and antennas.   I've since spoken to others doing the
same thing; if you have a lot of gear (interconnections), I recommend you
consider it, too.

Type N connectors are better than PL-259 for several reasons, including the
fact that they're much easier to assemble properly and are much more
moisture resistant when used outdoors. The connectors are slightly more
expensive, but I believe the advantages outweigh this slight increase in
cost.

[BVARC] Radio Repair Option

[Gus Bernard via BVARC]

Hi, all,

It's getting harder every day to find nearby radio repair shops.  Here's
one option, which though not in the Houston area, is in Texas.

Jennifer is a fellow AF MARS operator, who also repairs cell phones,
tablets, some laptops and other personal electronic devices.  She recently
repaired a smartphone for me - it was quick and easy to ship the item
to/from her shop using USPS Priority Mail.  Give her a call or email to
discuss your particular repair need.

Jennifer LaChance, KF5HCD
dba Device Rx of Texas
351 Co Rd 495
Muenster, TX 76252

[BVARC] Introduction to HF: Modulation and Propagation

[Gus Bernard via BVARC]

Hi, all:

This week I attended another very good webinar presentation I thought many
of you would be interested in, this time presented by the Rhode & Schwarz
sales team.

It's called Introduction to HF: Modulation and Propagation, presented by
R&S engineer Paul Denisowski, and sponsored by AOC Granite State and IEEE
NH MTT/APS Chapter.  It covers the modulation types most commonly used for
HF communications as well as the fundamentals of HF propagation.

It's great for Technicians interested in HF, or studying for the General
exam. It's also good for anyone who'd like a very well-prepared review of
the subject.

Below, please find links to various resources that came with the
presentation.  Especially interesting is the white paper, and the NVIS
paper.  There's also a link to register for an upcoming webinar on 5G.

Unfortunately, the link to the on-demand HF presentation webcast is tied to
my personal registration and I'm not comfortable sharing it with the
listserv.  However, if you contact the R&S sales team
, I'm sure they'll hook you up.

73,

[Gus Bernard via BVARC]

Soon as I get the link for the recording (and the PDF from Alan) I'll pass
it along on this thread.

BTW, I highly recommend his YouTube Channel
<http://www.youtube.com/user/w2aew>, which I've been subscribed to for
years.  I've watched more than half of is 300+ videos and there's a little
bit in there for anyone interested in the electronics part of ham radio.
He is (or was) a field applications engineer for Tektronix, and just
looking at all the test gear on his bench makes you salivate like Tim "The
Toolman" Taylor.

What sets him apart is his ability to present in a clear, complete and
methodical manner with great hand-made diagrams.  It's well worth perusing
his video playlists <https://www.youtube.com/user/w2aew/playlists>.

Re: [BVARC] Telescoping mast

[Gus Bernard via BVARC]

Marty,

I use 10' fence top rail "sticks" for both my Comet GP-6, and to hold-up my
130' Inverted L NVIS random wire.  The GP6 is at 35' (3.5 10' sticks), and
the Inverted L is at 25' (2.5 sticks x 3).  You can get them at HDepot or
Lowes for $12-15 per stick, but one of them is better (diameter and/or
thickness) than the other and I can't remember which is which.  You can
check the specs on their websites.

My 35' GP6 mast is mounted against my 2-story brick house wall AND guyed at
the top with 3 each 3/16" Dacron lines.  It's been up for years with no
problem.  At your house, you'll need to guy it well if you go to 35', as
you won't have as much wall support.  At 20', I'm sure you won't have a
problem.

Cheers,
Gus KG5OFB

Re: [BVARC] Best solder

[Gus Bernard via BVARC]

I agree with Jonathan 100% but would add the following 2 points:

1.  Quality sometimes matters.  Solder quality isn't a big deal for a PL259
connector, but may matter for other jobs.  So, I use name brand solder,
because there's better assurance of quality.  At a minimum, I keep good
quality 60/40 on the bench, because it's the most versatile and easily
available at a good price.  I like Kester, Multicore and MG Chemicals
brands; and

2.  Crimp, Don't Solder.  I use a 100W Weller iron for PL259 shields but,
even with a monster iron, soldering PL259 shields correctly (so they last)
is harder than it seems.  If you think this is ca-ca, show-up to help setup
one of our tri-club Field Days - one person sits for hours JUST
re-soldering or replacing coax cable ends - it's unbelievable.  As a Civil
Air Patrol COML, I spend crazy amounts of time fixing coax at every SAREX
or deployment.  The POINT is that *many *people don't get it right, *much *of
the time - not reliable, which is especially not cool in EmComm!  Crimped
shields, on the other hand, don't fail as often.  Even if they fail,
they're much easier to replace.

PL259 crimp connectors are available for shield crimp only, or for crimping
both the shield *and* the center conductor pin.  I think it is best to
solder the center conductor, but *crimp the shield*.  Crimp tools are not
cheap, but save SO MUCH time and hassle!  One good place to get decent
quality crimp tools and connectors at a good price is from Richard East,
N5IAW.  He often has tables at nearby Hamfests, and has an eBay Store
.  Some stuff he sells at
Hamfests is not on his web store (like, real Amphenol brand connectors) -
just email him to ask.  He's a good guy, who gives great personal customer
service.

73,
Gus KG5OFB

[BVARC] MARS JULYX HF Exercise - Invitation to General Hams

[Gus Bernard via BVARC]

 From 13 July WWV and WWVH will broadcast a MARS message on the 10th minute
of each hour on WWV and the 50th minute on WWVH. This coincides with MARS
national interoperability exercises held several times per year, including
the current JULYX. Each announcement will air for about two weeks, prior to
and during each exercise.

The broadcast will voice-announce information to Amateur Radio participants
regarding the purpose, dates, times and locations of the exercises and
other information. Tune into WWV/H on 2.5, 5, 10, 15, and 20 MHz for
information and any requested feedback.

[BVARC] MARS Announces HF Skills Exercise

[Gus Bernard via BVARC]

Members of MARS will conduct an HF skills exercise July 20 - 24 to hone
operating skills and messaging-handling capabilities. MARS members will be
reaching out to the Ham community via the 60 meters Channel 1 Net (5330.5
kHz dial) twice a day, the SATERN HF net (14.265 MHz), and by contacting
various stations via HFLink throughout the exercise.

Participating MARS members will be requesting assistance with collecting
county status information as well as airport weather information, called
METARs. MARS members will also be passing ICS 213 messages to numerous
Department of Defense (DoD), federal, and Ham radio addressees.

This exercise will be announced via WWV at 00:10 and via WWVH at 00:50
starting on or about July 13. WWV and WWVH listeners will be asked to take
an online listener survey. This HF radio training event will not impact
regular communications.

A Department of Defense program, MARS organizes and trains amateur radio
volunteers to operate in military radio networks to support HF radio
contingency communications. Among other missions, MARS provides
communication support to civil authorities and assists in establishing
normal communication under emergency conditions.

[BVARC] Georgia AUXCOMM presentation on FLDIGI with MT63

[Gus Bernard via BVARC]

 Somebody was recently asking here what the Houston ECHO Society was about,
and how it differs from BVARC.  Although now called a "general interest"
club, it's original interest when founded in 1974 was to promote and
provide emergency and public service communications in the Houston area.

Several of its members (myself included) are still very active in EmComm
and public service comms, and devoted to ECHO's original purposes.  Of
course, many of us are also members of BVARC, which is a much larger group
- hey, we all like hanging with people who like radio, eh?.

If EmComm interests you, you might want to attend the following
presentation about how many of us (SHARES, MARS, ARES, etc.) communicate on
HF - MT63 using FLDIGI.

ALL INVITED:
The Georgia AUXCOMM  group is
presenting a class on FLDIGI with MT63 on Thursday, June 25 from 7:00 –
8:00pm (our time).

Go to https://global.gotomeeting.com/join/990306637

You can also dial in by phone - (571) 317-3112, access code 990-306-637.
They'll record the session & make it available on their new YouTube
Channel:

Re: [BVARC] Emergency Power Quality

[Gus Bernard via BVARC]

Will, I think what you're looking for is a line/power conditioner
.  But, as has already
been said/suggested, it might be cheaper just to buy a new inverter
generator, and sell the old one.

Robert's option of feeding a battery through a converter/charger is a
common practice.  In this case, you'd operate the station from your battery
bank, which in turn is charged by a generator and/or (increasingly)
solar/wind.

[BVARC] Antenna for Sale

[Gus Bernard via BVARC]

Friend of mine (Tom Bishop, KG5POF) up in the Denton area is selling
his Cushcraft
X7 HF beam antenna .  (He just
bought and installed a new StepIR.)

The antenna is 10yrs old, but in really good condition and has the 40m
add-on kit.  It's off the tower and partially disassembled to about 5' by
18' (the boom).  Buyer will need to pick it up.

I think it's a pretty good deal at $700 (obo). Let me know if you're
interested and I'll hook the two of you up.

Re: [BVARC] Request for Surface Mount Resistor help

[Gus Bernard via BVARC]

Jeff,

any lab bench today should be capable of handling smd components.  There
are thousands of videos on YouTube on how to do it, and what tools to use;
spend a few hours searching around.  Dave Jones at EEVBlog
has done several
good ones.  So have Peter at TRX Bench
 and Mike at MikesRadioRepair
.  Doesn't need
to cost much.  I'm a tight-wad and here's what I use on my bench to handle
almost any smd work:

First you need good light and magnification, and you might already have
these.  I use a bench-mounted fluorescent light w/ good built-in magnifying
glass, and a Pro'sKit MA-016

headband.  I even have a $12 decent Chinese Daniu USB Digital Microscope,
which I hardly use because the glasses and my smartphone usually suffice.

Then, you need a hot air tool, tweezers and polyimide film tape.  See Dave
review the Atten 858D hot air tool .  My eBay
$30 YouYue 858D knock-off is probably from the same factory.  With that hot
air, you'll need a set of good tweezers and polyimide film tape.  Don't
scrimp on these last two - pay a little more for good quality sturdy
stainless static free tweezers made for working with smd, and get real
Kapton brand tape from 3M or other reputable manufacturer (some Chinese
crap is sold as Kapton, but is not).

Finally, you need the correct soldering iron tip for what you're working.
My ancient Weller TC202 
has no temp control, but works fine because I have a collection of tips for
it.  Your current pencil may suffice if you use the correct tips and
technique.

Good Luck.

Re: [BVARC] Running Cables through the Roof

[Gus Bernard via BVARC]

I second Andy's idea, using an existing penetration, if possible:  For
example, my cable TV coax runs out an existing attic "whirly" vent
penetration, between the vent's base (flashing) and the roof sheathing.
The cable travels under the surrounding shingle then exits towards a strain
relief at a nearby eave/soffit, and then to the power pole.

Re: [BVARC] Amateur Radio Mentor Group (AMRG) Presentation

[Gus Bernard via BVARC]

Rick, Steve's got a nice YouTube Channel 
where he's posted lots of videos testing and reviewing various end feds and
baluns.  Great stuff - I've seen them all!  I have one of the baluns he
dissected (a Balun Designs 9:1) feeding my random wire, and I'm pretty sure
Dave Ely's end fed is also one he featured (a MyAntennas model).

Re: [BVARC] Swr question

[Gus Bernard via BVARC]

I'd put an external SWR meter on it.  Every station should have one,
especially for situations like yours.  I HIGHLY recommend one with an
integrated wattmeter, and they're available used on ebay or other places.
Daiwa & Diamond are good names, MFJ has several models.  Or, you can borrow
one.

Meanwhile, check all your connections.
