While I can understand why one might think that it would be a benefit to
turn off the monitor and just have silence in your ears briefly, I think
that once one spends too many weekends with headphones on for greater than

Gary,
I did not suggest that the feature should not be added to the K3 nor did I
suggest that improvements not be made to the K3. Why do you claim that I
did?
My point is that in nearly 40 years of SSB contesting, it has become
apparent to me that those who use a monitor function to keep track
I like to have the monitor on very low during its use as at times I have
found that:
1) The wrong button was pressed
2) With the OII on rare occasion a poor quality transmission was in progress
which I could terminate and restart overcoming the problem. Problems can
also occur with the K3.
I have to agree that the K3 FW betas are unlike the typical betas - the ones
I've tried are cleaner than most companies' release versions of their
software hi hi. I do SW test development for a living and you wouldn't
believe the broken stuff I have had to deal with, even when it's called RC

I am adding a preamp to my K3 (SN 763) to help out with some weaker signals.

Casey,
If you have some 1N4148 diodes available, they will work. The only
downside is that they do not work as well as the 1N5711s at very low
power levels, and they are not as flat with respect to frequency, but if
you can tolerate those items, 1N4148s will serve you well.
BTW - due to the

To summarize, the designers of the HB-1A made some design choices that
differentiate it from the KX-1. For example, the battery

Thanks Don:
I bought this unit unbuilt from another list member and it is a very early
model. It has no vent holes at all !
I am driving with low power and therefore have the attenuator resistors
bypassed. So not worried about heat from that area.
I do have the feet on the transverter so
Let me piggyback with another somewhat related question. I have an Ameco PT-3
preamp sitting in the shack. It covers all ahm bands through six meters. I
plan on using it for SW listening (I do not have the general coverage module
installed on the radio), and for 6 meter operation. It has an
I'm considering the best way to approach the mods to my KSYN3 board. Doing
nothing or buying a second receiver are possibilities (the second receiver's
up-to-date KSYN3 could be installed as the main one). But if I decide to mod
my KSYN3 without spending a lot, a question arises.

So far, the preamp does a good job, now stations are readable i

I'm about to order the K3. I have an antistatic mat that I used to build the
K2 (#1760 - wow! that long ago?). Although it carries a few solder burns,
it still looks to be in good condition. I wonder if I should rely on it to
assemble the K3, or should I spend the 50 bucks and buy a new one?
Aaaah Bob, I was not singling you out and I do apologise if you felt
that I was. My remarks were meant only as a General Comment and
perhaps were not articulated well.
Regardless, I understand that compromises need to be made regarding FW
storage etc and so I leave that to the engineers at
Hello Jerry,
I am afraid that my observation with my XV50 and XV144 is different.
These transverters are extremely hot if they are run at Elecraft's advertised
rated output of 10W FM and 20W SSB. The heat is from the power module and NOT
the attenuator resistors.
For both XV50 and XV144,

Hi,
Please, see http://www.apogeekits.com/wrist_strap_tester.htm. It can test both

Hi Don,
Thank you for your help. Yes, it appears to be the VFO. The VCO readings
at TP1 for 20, 30, 40 and 80m are normal when the K2 is cool, but when
hot the readings are near 15,600 for 40 and 17,257 for 80. No wonder I
can't transmit or receive! 20 and 30m appear to be normal when hot.

Phil,
The problem will be found in the VFO Range Selection area. Look at the
schematic for the RF Board sheet 1.
Check the soldering of C71 and C72 and relay K13.
It is possible that when hot, the contacts of K13 (and possibly K14) are
not making good contact.
Set to 80 meters and wait until

Just to be clear, I'm not using the speakers with the radio, I'm using them

You would have to rewire the HM-36 for use with the K3 - the K3 uses a
