I have replaced a 25 foot with a 41 foot wire for the KX3. It runs to a
banana plug adapter from which I also spread out three 16 foot ground
radials. A 5 foot length of RG-59 runs from the KX3 to the banana adapter.
This is tuning to less than 2:1 SWR on all ham bands except 160m. I find 41

I had the same problem with a 25 ft wire, but after lengthening it to 41
feet the KX3 tunes all bands from 80 to 10 to less than 2:1 SWR.
Be sure to do a second tune if the first one doesn't get you where you want
to go, sometimes that makes a difference.
When portable (but not backpacking) I hav
I'm amazed at what a high proportion of my contacts recently have been ops
with KX3s. I'm sure a lot of it has to do with it being relatively new, so
will get preferential use from hams who have plenty of options, but it
still surprises me. I'm only doing CW and hanging about the QRP watering
holes
Thanks to all who replied with advice or hardware to offer. A list member
has presented a nice Thunderbolt package that could not be passed up -
thanks Chuck.

I would like to fine tune my KX3 for maximum frequency stability, and also
calibrate my frequency counter (and get some idea of its warm-up drift).
So, anyone willing to lend out a Trimble Thunderbolt or similar GPSDO? I
would even buy one if someone was ready to let one go.
Thanks and 73,
Chip

I'm very impressed with the RTTY mode in this little bugger. It is doing a
good job of decoding signals in the JART WW RTTY contest, and with it's 10
watts into my trap vertical stations in Poland, Finland, and Ukraine are
reading it fairly well. Using the CW memories to hold the exchange makes it
Im no contester or DXer, but generally the KX3 seems to pull signals out of
the noise with narrowing filter width better than the several k2 units Ive
used. The noise also seems less harsh. I havent found the APF to my liking,
it seems to ring too much compared to just narrowing down the passband.
Is there a better NiZn implementation out now? I was very disappointed with
their charge retention and ultimate life when I tried them about two years
ago, and I gave up on them. In any event, the KX3 charger is unlikely to
charge them properly like you suggest.
Definitely go for Sanyo Eneloop cel
