into the making the P3 a very useful station tool.

When delivered, it would have the requested features and even more. Isn't it?

As your post indicates, the splattering of JT65 signals has most likely
nothing to do with your transmitter and setup. It is more likely to be due
to the specifics of the JT65 display/decoding algorithm than anything else.
I have done spectral estimation for some 30+ years and it reminds me very
If your neighbor tells you it's clean (and s/he knows how to look) then it's
likely the other station at fault. Noise blanking, noise reduction, poor RX
audio (over)driving are huge issues that can make any reception look bad.
Bottom line: don't sweat it if your local stations tell you

another Ham band, so it was not obvious to the operator.

FWIW, overload from a strong local signal can cause much weaker signals
That clears up something that has bothered me on JT65. Many times
someone will complain about someone overdriving, but the signal appeared
to be OK to me. It happens frequently. Now I think the complainer is
probably receiving the station much more strongly than I am and it is
overdriving his
Well nothing would put the issue to bed better than a nice printout of a P3
screen that was sampling the RF signal over a bandwidth of about 6KHz.
That's why I would LOVE for Elecraft to continue developing the P3 and
expanding its capability.
I don't mind the report, and I take it seriously,
Yep, that is 100% correct.
If the station that is offended would simply reduce their RF gain control,
in most cases they will see the signal clean right up. Then the real issue
is that they want to copy a weak signal that is in a chunk of spectrum that
is full of strong signals (most likely due
My normal technique with sound card modes (mostly PSK31) is to
look at the audio AtoD overload indicator in my software and
reduce the RF gain so it indicates no overload. This procedure
uses the minimum necessary gain through most of the radio/AtoD
etc, limiting local distortion products. It

Even if they never add the feature, wouldn't it be better to use a

I don't have a P3, so my curiosity is only academic.
The sampling function being referred to, would bring a low power
sample of transmit power to the P3? This does not seem very
difficult to roll your own sampler. I gather the P3 has the needed
RF ckts to receive RF and demod it, or is
Hi Tom,
It's become very difficult to locate an SM-230 monitor in the used market and
even when you do, they are asking an arm and a leg. I've got a pretty clean
one, but I can't find anyone who seems to be able to service the unit. As you
state It does do a pretty good job though for
What if one defined the IF of the P3 to be at some PSK frequency and
connect a loop of wire to it's RF input? Put the loop on the desk.
There might not be enough resolution to clearly see anything but gross
PSK signal infidelities.

A basic transmit monitor (amplitude domain) is extremely easy to
Resolution would be the same as on received signals - frequency resolution of
span/450 and amplitude range 10 - 80 dB. One gotcha is that the P3 only
handles IF's up to 21.7 MHz so presumably there would need to be some
hardware to allow up to 54 MHz.
