Hi Jim,
I’ve discovered that it’s easier to see a very weak signal on the waterfall
than in the amplitude plot. Setting the SVGA screen for 25% spectrum and 75%
waterfall gives lots of space to see dim traces. You may have to adjust the
threshold a bit.

According to the schematics, those two double pots on the front panel are
merely voltage dividers. They provide 0 to 5v signals to the front panel MCU
which controls the function, eg: AF_GAIN. It’s possible the pot has developed a
dropout right at the point where you usually set the AF level. Ma

My K3 is #4113 factory assembled and delivered in April 2010. I'm pretty sure
the bottom cover had never been off when I did the update mods a couple months
ago. That's when I asked Elecraft support about it and I assumed it had been
added to later #s. I've never had any issues but run mostly CW
For folks who run lots of high duty cycle modes, Elecraft is now recommending
'thermal pads' between the LPA transistors and the bottom cover. I found this
out when I was doing some mods to my 10yo K3 and the instructions said to
install them and I didn't have 'em. You can get them from Elecraft
My K3 is also from 2010, April as I recall. I recently did the component mods
you mentioned except for the KREF3 and KPOD resistors. Also I added the general
coverage BPF board with 472 kHz in mind. I added the new synthesizer as soon as
it came out. It all went very well and only took a few hou
A properly equipped K3 or K3S is a good receiver on 630m and as Don pointed out
will produce 0.5 mW from the Xverter interface. I've made the mods and checked
the output on my 10 year old K3 and it's good to go.
There are several amplifier designs on the web that will give 50-100 watts
output a
You can use DTR keying as described in the thread or you can use the "KEY"
macro in N1MM+ via the serial port CAT interface. I use DTR with my K3 but
since DTR keying isn't implemented on the KX2, I use the macro. When using the
macro the speed is that set on the K3 keyer and can be interrupted
I have experienced this too. Cleaning the contact with a small strip of paper
helps for a while. I'm wondering if the contact closure current may be too low
to overcome the slight surface corrosion that develops over time.
When not in use I store the KXPD2 in the mesh pocket of the CS-40 case.
There is a P3 menu item called "Turn VFO B cursor on/off". I don't have
the subreceiver to check but I think that will do what you want. GL

Yeah, unfortunately it is. It's Windoze checking out the serial port
connection. You can avoid the problem by setting CONFIG:PTT/KEY to
OFF/OFF. I have one of the PF keys programmed to access that menu item
so I can set it up on the rare occasions I use computer keying (N1MM+).
Sorry I mash

Taking the long path no doubt :-)
