Hello Frank
May I ask what relays you use? I imagine there are some high voltages under
some conditions. Do you run high power?
Thanks

When I sold my K2/100 with the SSB board and the Yaesu knob one year
ago, I think I got around $850 to $900. Mine was in pristine condition
with all boxes / paperwork and included a custom felt embroidered dust
cover. It was 2 yrs old, SN 4000-something.

K2/100 s/n 0473. I found out the hard way that the deal I thought I was

date.(Firmware and Hardware) Still have more to go! Buyer beware.
Don,
thanks for that information.
Here's what I have. TX appears fine. With 12.3V supply I get the
following output: 80m 3.3W; 40m 2.9W, 30m 3.8W, 20m 3W. All measured
by an Oakhills Labs QRP meter and a 50 Ohm dummy load.
The RX seems to have a problem. I have done a careful check of all

Hello group,
a friend of mine has a strange problem with his tx power after upgrading
to firmware 3.03. However I couldn't reproduce it with my K3 (also 3.03)

Firmware beta 3.03 significantly increases the number of settings automatically
stored for the KAT3.
Are the settings stored on the KAT3 board, or is general storage used?
The KAT3 schematic shows three critters, but it's not clear to me if they are
capable of both storage and relay control,

Outstanding progress on the K3.? My next to last request has been finalized;

I would be interested in the details on your switching arrangement,
including the relays and power level you are using.

Hi Paul,
The ATU settings are stored in the K3's front panel EEPROM.

Fast-tuning birdies are a function of coax cable locations and

These fast tuning birdies depend on the mode selected, the roofing filter

A lot of guys here at work have the Bose NC headphones to try to cancel
out nearby office noise. I suspect they work OK in that application and
no better.
Doesn't Bose have a liberal return policy? You could answer your own
question by ordering a pair and seeing if they work for you. If not,
I tried a pair in a bose store and was unimpressed, cant turn the gain
up enough, so I built my own, they are a safety hazard now :)

One other comment in this thread re: RFI. I've not seen the Bose
