Just a general question, thought my new power supply was dropping voltage
on TX but no it is rock solid, I get about 1V drop at full power CW on the
K3 Display. Is this normal,
I have already replaced the troublesome PA pins is there something else
that would cause this.
Don't think the drop over

Well,
Yet another fault in my shack the K3 decided to stop putting out power over
12W this last night and came up with the Error "12V ERR" so off to the
internet to see if it was an easy fix, well yes and no.
Turns out i is a common problem in older K3 mine is 891 not ancient but
older and as the
This is strange,,
My K2 is now Transmitting Max 15W on 80M CW but power drops off as I go up
bands 6W on 40M about 3W on 30 and not much at all on the other bands.
What would cause a pregressive drop off like this , PA must be ok otherwise
I wouldn't be getting 15W out on 80M .
I have adjusted t

HI,
OK this is probably a hard question but I am looking at something other
than a straight key to try my hand at CW again. Thought it time to go back
to basics and QRP.
Single or Dual paddles , suggested paddles?
Open to suggestions ?
thanks in advance,

Well I finished the K2 only to find no TX preliminary troubleshooting seems
to suggest the T/R switch D6 and D7 are not getting the control signal from
the control board, Also U9 shows higher voltages ,
Is there anything common that may be wrong, All bands peak fine on receive.
thanks for any ide
I just found there is a SSTV repeater in VK5 on 14236 and it requires a
1750Hz tone for access,
any way to do this ?

Don't know if you got your answer Al but VFO TRK is a ECSS (Exalted Carrier

Amateur AM reception to minimise fading and with selectable sidebands

Hi,
Intermittent Buzz from relay on IF I/O board in P3 any fix ?
I have completely re-soldered the board and checked it as the current
schematic and all seems ok,
Sometimes it will buzz continuously other times intermittently, really
annoying. and the display jumps at the same time.
Any ideas?
Hope someone has an answer,
I am a recent owner of the K3 having just bought a K3, P3 and KPA500
station from another ham.
Probably you would have to be a regular user of the JT65 mode to notice but
I seem to get little or no output when I am below about -500hz or so on the
