Murray,
Not only logical, but the only way to approach Transmit problems.
When you get to jumper W6, know that you can and should adjust the
bandpass filters for maximum RF voltage there.
On a new build, be aware that the most common problems are soldering,
misplaced or incorrect components
Don,
A logical suggestion. I already have made the RF Probe and it's ready to
use. I was hoping the cause of no power might be something simpler. I
will start troubleshooting in my next work session.

Murray,
I suggest that you build the RF Probe that was included with the K2
kit. The schematic is shown on page 9 of Appendix E along with the
assembly instructions.
After that, start on Appendix E page 12 - Preparation for Transmitter
Signal Tracing and follow the steps shown there.
73,
I am just completing the build of K2 Serial No. 6397. Everything was
going perfectly with all receiver tests and adjustments. Everything is
in spec.
Then I started the transmitter tests. I set the output power control for
2.0 watts. Beginning on 40 metres, I am supposed to be able to adjust

Frankly, signal strength means little to me. The "copy-ability" of a

One thing that has always concerned me about "ham signal reports" in
general. I've heard signals that were 20 dB over S-9 that were great
sounding signals. And I've heard signals that were 20 dB over S-9 that
were lousy or terrible sounding signals. Likewise, for those that are
only 6 dB
When I first posted this subject, I asked for 6 beta testers,
4 of my prototype battery monitors went out to responders today by USPS
first class. ! more is scheduled to go out Monday.
Thank you all for your interest in my project.

Jerry,
You will still want to remove the front panel to check the wiring of the
microphone configuration header.
It must be wired to match your chosen microphone.
Since you did not build that K2, you may not know how to get to the
Front Panel.
There are disassembly instructions at
Hi Will,
Make sure you're not in TX Test mode, and also make sure MENU:TX Inhibit Mode
is set to OFF.
Please contact me directly if you continue to have issues.

Hi John,
That was it! "OPt" was set to Batt. Changing it to "Perf" fixed it.

I recently received my K4 SN #153 a couple days ago. I transferred all the
antennas, microphones, and CW keys over from my K3 but have run into a few
problems.
First, I have tried transmitting in CW but cannot get the radio to transmit
anything. I have tried two sets of paddles and ensured I

Just for yuks, I opened it up to seewhat if the SSB adapter had been
installed,
and somebody pulled it out?
Sure enough, C167 was tacked messily to the top of the board.
According to the
schematic, you remove that when you install the SSB adapter.
That's good news. It means I just
