Eh? A 40m dipole is pretty close to resonance on 15m already, so how can you
avoid that. In fact, all dipoles are resonant at odd multiples of half waves,
so this is impossible to avoid.
Could you clarify the issue here?

I failed to mention another point with regard to fan dipoles. Do not
mix 3rd harmonic radiators on the same coax. In other words, stay away
from combinations of 40 meters and 15 meters, and also 40 meters and 30
meters. They may work, but tuning problems are 'iffy'.

Strongly agree. A
FYI, I am running Data A mode for digital operation with a SignaLink modem.
Split mode does not appear to be available when running under Data A.

This may be a simple question, but how does FLDigi run wide (>2.5Khz) split
with the K3?. The waterfall does not allow the transmit frequency to be locked
further than the sound card bandwidth from the receive frequency. FYI, I do
not have the K3 sub-receiver installed. I presume some variati

Although these are rated at 15 watts with a heatsink, they are rated for

Ed,
Since he does not want a beam, I would suggest 3 dipole antennas
supported from his 80 ft. tower - OK, really 8 dipoles, but 3
feedlines. All of them would be inverted VEE type.
One of them is a fan dipole for 10/15/20 meters. Position that one to

Thanks to all who replied! I reseated all cables and I believe the problem
is corrected. I also downloaded the latest firmware just in case, so all's
well with the world.

I have asked the same question to Eric at the HamRadio fair in
Friedrichshafen. From what I understood, you don't need the mod because
you can either operate on VHF or on HF. The mod makes sense if you have
another VHF radio which you like to operate in parallel to the KX3.

So the K3 does not send data unless polled? OK, now things make more
sense. This explains why, if you're not using the Y connector to your
computer, your data cable must have the TXD wire so the ACOM can poll
the K3.
Is my assumption correct
In my case LP-Bridge seems to be confusing the amp but I can't tell
why. LP-Bridge does read everything correctly from the K3 and
Win-Test works perfectly along with it.
LP-Bridge acts as a *proxy* - polling from Win-Test and other programs

Hi Dick and Val
Thanks for sharing this valuable info with the group.
Similar to Bill, W6WRT after I fixed my CAT cable to exclude TXD line my
entire setup started working but later on I realized it wasn't working
reliably. On some occasions, amp would not detect the frequency change
until after
Definitely use the ohm meter check. If I remember correctly there were some
pwr cables that had the wires reversed. I never trust the colors too much
at risk.

John,
Thanks for the tip.
I have a hard time filtering the F.O.D. on the KX3 Yahoo group. I'll go
back and look there too.
I have set the DLY and finally got it where I can tolerate the key
clicks, but the DLY is set to about 0.20 - basically, it only clicks at
the end of transmit.

I'm not sure what I've done. Not sure if I just woke up and noticed it

With my KX3 terminated into a dummy load, split and dual watch active,
VFO B 1 - 5.3 kHz up or down from VFO A, filter set to 450 Hz and
centered, I am getting key clicks on VFO B
Bill,
When K3 AUTOINF menu entry is set to NOR, then the frequency is
reported only when polled.
Only the loger polls as the Y cable does not allow the ACOM to do it.
That is why K3 does not report the frequency when the logger is not
running.
The issue can be solved in two ways:
1. Set AUT
KX3-2M: high speed CW (e.g. 35 wpm) with external keying sounds strange
in sidetone on 2m. I have no RX to monitor RF. With the internal keyer
it works perfect.
On HF bands CW sounds perfect!
