I find these comments fascinating and highly appropriate for a K3 forum.
The K3 with its modularity and close communication between user and
manufacturer is the ideal place for adapting new technology to HAM
radio.
As a heavy user of technology outside of HAM radio, I think I have some
opinions
I can't get the custom settings for NORM1 or NORM2 to save.

I updated my firmware to 4.14, but still no joy. I did have the K3 lock
up last week and Elecraft support walked me through a hard reset. I
thought I had things back to normal, but now I'm not sure.
No matter what I SAV, NOR always goes to the default 400hz on I or II.
Yup, thanks

Ah! That's the ticket. I missed the part on the hold AND twist to get

BT is a great idea, but to do it right, you wouldn't want to make it
available for only mics speakers. Once you have the BT chipset in the K3,
there's no reason why you couldn't implement BT serial connectivity to a

Hello guys.
After using a battery for 9 months with my K3/100 I need to spend some money

good reviews. The question I'd like to ask has to do with whether you'd

I've been using the Samlex 1235 with my K3, with no problems. So far, I've not
detected any RF from it.
However, it does NOT have built-in overvoltage protection, which means if
anything goes wrong with its voltage regulator it could fry your radio. I
prefer not to take that chance, so I
I've got the Samlex 1235 with the meters. One of the meters was way off
calibration. When the fan kicks on, it's really loud. I quit using the thing
and got a nice Astron 35m which is totally silent. I hate fan noise.

If you're after decent shielding to keep RF out of the circuit, Radio Shack
might have what you want. Nowadays a high impedance is typically 1 or 2K
ohms instead of the 50K ohms are more common a few decades ago. Audio cable
shielding has been reduced accordingly - especially from lower-cost
AD5X tested the Samlex 1235, and also describes a very simple mod to run the
fan continuously at low speed. With the mod, the fan probably won't run at the
high speed during normal operating. If your K3 is drawing enough current to
turn on the PS fan, the K3 fans will probably be running
Hi,
I'm planning to activate Little Bald Mtn [CA - SOTA W6/SN-046] this weekend.
PlanA: Sat 16 Oct 2010 1700Z to ~2000Z. 14.061 for the first couple
of hours, 10.116 for the last hour. I'll try to post to QRPSpots.com
with my phone but I don't know if I'll have service, and I'm not certain
Look at supply current and see whether the current increase with time? I have
heard that some PA suffer from overheating IF trap.

Tried that. It was also too loud. The K3's fan is quiet. I also have the

I agree that search-able .pdf schematics are a godsend. I would not be
without them.
However, I did download and print the K3 schematics. After I locate
what I want on the search-able .pdf, the printed schematics provide me
with a reference point from which I can trace signal paths.
Good point, guy. I discovered the minimal shields when I bought an AUDIO

surprise when I was greeted with tons of 60 Hz hum. That was when I

Ciao Mike,
the first time I note the problem I was in 21 MHz working in SSB with the

The power of K3 was set to max 50W for 1 KW output of the ampliefier and I
see the power drop down to abt 200W output.
After I investigate and I switch to FM and CW just to test different
