Well Rich,
Guess you are a late comer.
I got my ham license at age 14 and I am now 77. I've been married 18
years. She was married to ham before me, so had been "broke-in" before
getting "saddled" with me (western sayin). That was the good news and
the bad news.

Hello Elecraft List
Some guys were sending .jpeg's back and forth on 80m this morning and I asked
them what program they used.
All were using EasyPal from EasyPal.org (free) .
So I received several pix from the group but was never able to transmit.

Hi All
Update on the K2 and its problems or now lack of them.
Finished setting up the filters and other than getting ‘low Batt’ indication
now and again all appears to be well.
Fitted the KAF2 and set up the clock, that taxed my grey cell but managed it in
the end.

Years ago...about 30, I had 2 ele 40, th7 and th5 and Higain Hightower and

I have got a k144xv transverter and fm filter that I was going to install for
vhf contesting and wound up with another option in the shack before I could get
this installed.

No. See my post in this thread about resonance.

Having difficulty loading latest version of the Kat500 utility. The

check sum is not zero”

Pete,
Yes. You either have to have lots of them, or you need to get bigger ones and
run multiple turns through them. Also get the right “mix” for the frequency
range in question. Type 31 is pretty good for HF.
Not an expert, but studied http://k9yc.com/RFI-Ham.pdf
The KAT500 Utility software is v1.21.9.15. Use it to download and install the
KAT500 v02.05 firmware.
Have you tried under Windows?
It's always worked perfectly for me.

Just checked my KAT500 and it had V1.75 installed. Then with the KAT500
Utility, version 1.21.9.15, I did download the firmware from the
Elecraft site and install V2.05 into my KAT500. I saw no issues.

That's right, sort of. But it misses the
The impedance increases with the square of the turns. 2 turns = 4 times

For those using the clamp-on ferrite devices, when installing them, be
sure part A closes completely and solidly contacts part B. Otherwise,
there is no flux path and the device is ineffective. If it is closed

Make sure the switch on the Control Board is in the INT position.
If using a battery, it may have a low voltage - it must be higher than
