Good Evening,
Two whole days have passed with no snow fall. What a relief,
February was interminable. But even with the warmer temperatures it
will take a while for all the ice and heavy snow to melt. It sure is
nice to see the sun again.

Jim,
Unplug the K160RX and then plug it back in to wipe any oxidation off the
pins. That may or may not help, but is one easy thing to do "just in case".

OK. One thing common to it all that could be affected by the flexing of the RF
board, is the J14
connector assembly. It looks like it could be a bit fragile, since it's so
tall. I'll check it again,
and then start tapping.
Thanks again Don. 73,

Jim,
K1 and the entire 160 meter low pass filter is not in the path for the
RX ANT, so changing K1 will not help.
Remove the top cover (you can operate like that) and tap on things
gently with a pencil eraser to see if you can locate the problem.

Switching to the RX antenna has no effect. The only thing that seems to work is
a tap on the back

touched up all of the solder joints on the 160M board, and on J14. Maybe K1 is
bad, but I'll
Jim,
Replacing K8 is not going to do anything for 160 meters. The relay that
switches in the 160 meter low pass filter is K1 on the K160RX board.
Try this the next time it happens - while on 160 meters, change the
antenna to the RX ANT jack and set the RX ANT menu parameter to ON. See

With the nut loose, it is much less intermittent. When it does hang up, a tap

Loosen the nut on the BNC connector or remove it entirely. Since the

Asking 75 for the package including all items, plus a couple of bonus

Hi,
I have an ALS-1306 amp, and Elecraft control cable for sale. Bought a
KPA-500, so the ALS is no longer needed. If interested, contact me OFF

Yes, that is the new diode for D10. Unfortunately the manuals have not
caught up with the parts available.

I am building a K2 and on the RF board there is diode D10. It's listed as
95SQ015. I cannot find this diode in the RF bags. I do find SR1503 which
has the large black body that I'm to be looking for. D12 I found.
Do I use SR1503 or am I missing D10?

Richard;
What do you mean by “things go into default”?
The KPA500/KAT500 combo should play very well with the 7610. exactly what are
you seeing?

I'm considering replacing my KPA500/KAT500 with the 1500. On the shack desk
I use a K3 and Icom 7610. Of course the KPA/500/KAT500 combo plays very
nicely with the K3, but I seem to be having some tuning issues occasionally
with the 7610 particularly if I move to a different part of the band -
If your K3 has the KXV3 option installed (a row of 5 BNC connectors just
above the CW and PTT keying jacks on the lower right back panel), then
there are two ways.
1) Connect the SDR to the IF Out jack and tune the SDR to the K3's IF (8215
kHz). You can receive signals in (or near) the same band
Just bought a K-3 from a friend, so I'm a total newbie. Apologize if this
question has been asked before.Is there a way to connect the SDRplay RSP2 with
SDR UNO (or HDSDR) to the K3?Tnx,Bob K4RLC

Hi
PA temp readings jumping from -110C to 110C, looks like troubles with
temperature sensor. Where to start dig?
