2007-09-04 Thread Mychael Morohovich
Hi, John-

Since I am the fellow who provides the pre wound toroids, I would like to
offer that I do include a note with my K2 sets instructing the builder not
to pull the leads too tightly while installing K2-T2 . Its design is a
little unusual insofar that the toroid is spaced slightly up off of the
PCB, its green secondary leads hidden under the core. I tin most parts up
to or onto the core itself, and with this part care must be taken not to
distort how the lengthy green leads are positioned since this could result
in pulling some enamel into the PCB.

 It was definitely a improperly tinned green lead on T2.  So much for
 buying pre-wound/tinned 'roids to save me some grief.  Heh.

Re: [Elecraft] Toroid Winding Question

2007-07-05 Thread Mychael Morohovich
Hi, Kevin-

Some of the ferrite cores can be a bit rough around the edges. When I
encounter a batch that exhibits this characteristic, I use a drill-bit to
clean up the burr prior to winding. Pick a drill-bit of a size
substantially larger than the toroid's inner diameter, and spin its tip
back and forth a few times in the toroid's hole. You should fine that the
burr comes off easily. I don't usually have trouble with the OD of the
toroid, but in that case you could use some fine sand paper.

Wow. A thread dedicated to me! It has been pleasing to read the nice
comments from my fellow hams and builders. 

When someone new to toroids is on the fence concerning the decision to wind
their own parts or use my service, I tend toward advising them to try their
hand at a few first. If it isn't to their liking I will ship out whatever
sets they need the same or next day, depending upon when I receive their
request. 

It is worth noting that sometimes the decision to wind or not to wind is a
decision having to do with ability. For a variety of reasons, from poor
eyesight to reduced coordination, there are those who find my service
invaluable. As has been pointed out here already, some find it a boring
task or are simply tired of the winding and tinning.Whatever the reason, I
am always pleased to fill those toroid orders.

Think of the antenna and everything connected to the ground terminal of
the  KAT100 -- including the counterpoise -- as an off-center fed antenna.
When you removed the counterpoise, you moved the feedpoint.  This changed
the impedance seen by the KAT100 ... 73, Vic, K2VCO


Thanks Vic, I get it now: the method that I am using is valid only when the
antenna is 1/4 wl or less. Since my EFW is 86 feet, it would only
be useful trying this comparison on topband where a 1/4 wl is roughly 125
ft. It was suggested off list that my best bet overall is to employ the
use of a field strength meter. Perhaps it is time to invest in one!

the KAT100 reported a flat SWR for the antenna while the Artificial Ground 
reported maximum current into the counterpoise. Using the rf sensor, I 
measured the current of the antenna [and counterpoise because I was curious] 
at a spot close to the back of the rig. I then removed the counterpoise, 
retuned the antenna for a flat SWR, and measured the current again for 
reasons of comparison.


This showed me the amount of current that was going into a properly tuned 
antenna both with and without a tuned counterpoise in place.

Re: [Elecraft] winding toroids

2004-12-05 Thread Mychael Morohovich
You do not want to pull the wire too tight when winding toroids...Copper 
wire is malleable and will stretch, possibly separating it from the enamel 
and allowing the enamel to flake off...  Jerry, wa2dkg

---

In the thousands upon thousands of toroids that I have hand wound while 
supplying toroid sets to Elecraft builders, I have never personally had this 
problem. I have had the wire break on the occasion while trying to snug up a 
toroids lead using too much force for the gauge of wire with which I am 
working [try working with KSB2 toroids immediately after winding toroids for 
the KAT100 QRO tuner- hi!], but I have never had enamel flake off despite 
the fact that I sometimes exert enough hand force to break cores, 
particularly those using the heavier guage wire.


I think that it is important to realize, however, that these toroids do not 
have to be wound with their windings absolutely flat against their toroidal 
cores. Hand snug is plenty good for our HF applications and is all that is 
expected of the builder. As the Toroid Guy, I am supplying a professional 
service and therefore strive to provide toroids that are as perfect as 
possible in every way. Less than perfect toroids in terms of appearance- so 
long as the stripping and tinning is performed competently so as to assure 
good electrical connectivity when they are soldered to the PCB- will 
certainly suffice toward helping to get those kits on the air.

Re: [Elecraft] Muting the K2

2004-11-10 Thread Mychael Morohovich

Hi, Bob-

I don't know if this applies to your situation, or if it is the best 
available scheme really, but I use my K2 for RX when I am operating with my 
Johnson Ranger TX.  The best way I have found to do this is to key both in 
parallel, the K2 in TEST mode so that it mutes RX in synch with my keying. 
This allows me to have side tone and QSK abilities, along with superb K2 RX 
[using an antenna separate from the one on which the Ranger is transmitting, 
of course].


Since the Ranger puts considerably more voltage across the key than does the 
K2, I key the K2 directly and use a relay between my bug and the Ranger.

Re: [Elecraft] KAT 100-1 vs KAT 100-2

2004-11-09 Thread Mychael Morohovich

Hi, Jim-

Th reason for the larger enclosure is that a lot of ops prefer to remote the 
KPA100 together with the KAT100-2. This of course requires the larger area 
afforded by an EC2 external enclosure which can be purchased separately. The 
KAT100-2 kit slips inside the lower part of the EC2 enclosure and includes 
front and back panels. The KPA100 fits in the upper portion, its heatsink 
making up the top panel of the enclosure, just as it does when it is 
integrated into the K2.


The self-contained KAT100-1 comes with standard feet, but a bail can be 
ordered. I use this bail on my KAT100-1. Since the K2 is placed directly 
atop the KAT100-1, it makes the bail of the K2 superfluous.


If you are at all interested in remoting the KPA100, excellent info in this 
regard can be found at: http://www.fidalgo.net/~wa7gxd/k2kpa100.html

Re: [Elecraft] KX1 Random Wire Antenna recommendations

2004-08-07 Thread Mychael Morohovich
Hi!

In my experience, the counterpoise can be a tricky thing. Keep in mind that
minor changes in ground current can lead to substantial swings in antenna
impedance. That translates directly into changes in SWR. For instance, I use
an MFJ Artificial ground to tune a counterpoise for my 85' EFW. There are
some bands that I simply cannot match with a low SWR if I do not have my
counterpoise adjusted to see maximum current. On other bands the peak is
rather broad and it isn't as important.  Using end fed wire radiators can be
VERY effective, but they tend to take more effort for multi-band operation
if you care about keeping the ground current optimal for maximum efficiency.

It is not necessary to use an AG for series capacitance and inductance if
you are willing to either use a separate wire per band or adjust the length
of your counterpoise by either trimming it or folding it back onto itself.
The AG is, of course, more convenient and allows one to use the same 'poise
for more than one band- within reason (I use a separate 'poise for top band
and 80 meter ops).  To get the length right (the point at which the 'poise
sees maximum current) you will need some method of monitoring the current.
My MFJ AG has a built-in meter for this. You can also use a small light bulb
at the rig as an indicator and tune for max brightness. Of course, what you
are theoretically going for is a counterpoise of 1/4 wl, but it is not as
exact as this and some form of adjustment is helpful. QSYing within a band
can sometimes require a slight adjustment in ground current as well if the
antenna exhibits a high Q.

For antics of the pedestrian mobile sort, I would probably use the
cut-and-try method to get the right counterpoise length per band if the SWR
was giving me trouble. One other thing worth noting is that I have found
with my KAT2 and KAT100 auto-tuners that small amounts of either capacitance
or inductance added in series between rig and antenna can work wonders in
helping the tuner find the right L/C combination on problematic bands. I
have a 335 pF air variable with banana jacks soldered onto frame and stator
that I use for this, as well as a goofy looking toroid wound on a T94-2 core
that is tapped at regular intervals with more banana jacks.

Re: [Elecraft] Like MFJ's 931 Artificial Ground ?

2004-08-02 Thread Mychael Morohovich
Hi, Bill-

Unless I am mistaken, there is supposedly a schematic available for the
MFJ-931 in Devoldere's Antenna and Techniques for Low-Band DXing.

I have the 931 and use if with my EFW, both in the shack as well as while
portable. It works well for me, plus one cannot have too many gadgets
containing wiggly meters hanging around- hi. If you cannot get a copy of the
schematic, let me know off list and I'll open up my unit and trace something
out for you. As I recall, it is a simple variable L/C network whose output
passes through a toroidal transformer that provides current info to the
front panel meter. You could of course dispense with the meter and use a lil
light bulb to help tune for maximum current.

No problem, Paul. Your 3 watts barely made it here to Western PA, but I did
manage to get your call sign . When you sent /PM, I had to think about
that for second. I believe that Wayne has managed to start a new trend with
the ol' peripatetic technique- hi.

Ron AC7AC generously sent me his KX1 (SN#3) to play with. I'll have to get
it out with the intention of jumping on this /PM bandwagon!

73 es tnx for the QNI,

Mychael

[Elecraft] ND7K/P QRV from Bailey Island NA-137 on 14.040 MHz until 1500Z July 12.

2004-07-12 Thread Mychael Morohovich
Chuck is a friend from a morning CW net. NA-137 is Maine West and is on the
IOTA Directory's  Most Wanted List. Condx not the best today, but I just
managed to work Chuck from my QTH in Western PA.
