The AF Gain pot on my K2 is getting loose. ?I suspect it will last another
year or two, but since i use it daily, I thought it would be good to replace
it with a better part. ?Everything else on it has held up well and exhibits
not wear, other than the usual scuffing. i did have to replace the headset
jack a couple of years ago but decided for that, that dedicating a headset
to the k2 was easier than replacing the jacks.

So the question is, has anyone identified a more durable replacement?

It's been a great radio. ?I like the looks of the new KX3, but there's
something very sticky about a radio you've built yourself.

John,

If I recall, your K2 is an earlier one.  The currently supplied AF Gain
controls from Elecraft have a metal sleeve around the shaft and are much
more durable than the first ones.
I do not know of a more durable replacement other than those currently
stocked by Elecraft.

If your K2 is below SN 3000, I suggest adding the Alternate AF Gain
Wiring Mod to your K2 at the same time you replace the AF Gain control.

73,
Don W3FPR

Martin,

They're not very common, but a MFJ-210 "Digi-dial" might be what you're
looking for. It takes the VFO output (5-5.5 MHZ) and mixes it with a crystal
to compensate for the IF, then feeds into a conventional frequency counter.

The following link has what looks like text from an ad for the product, and
it
specifically mentions the TS-520:

<snip> Order MFJ-210 for any rig with 5 5.5 MHz VFO (TS 520, S, SE; TR 3, 4;
HW 100, 101: SB 101, 102, Tritons; etc).... <snip>

http://www.marcradio.org/rm-1981-10/a-meq.html

(I actually have one in unopened plastic and original box that I came by in
a
package deal sometime in the past, but unfortunately it would cost way more
than it's worth to ship it across the pond....)

73, Al

KRC2 built.

It appears there are a couple of ways to wire the KRC2 with the K3.  I
have the KPA500 and am using the Aux bus so I think I should use the aux
bus.  The KRC2 will be used to drive an ICE 419 Bandpass filter unit.

I would appear that all I need to do is connect pin 6 on the KRC2 to pin
2 on the 15 pin connector and pin1  to pin 5.

Why would one want to hook up using serial ports with or without logging?

The entire setup will consist of a Microham MKII keyer or MK2R+ , K3,
KPA500 and KRC2.  It would appear that I would need another 15 pin
splitter to run the MKII, KPA500 and KRC2 all on the the Aux Bus.  I
assume that the splitter that Electraft provided is 15 pins straight
through?

IN that situation I'd use a counter to read the transverter output frequency
so the accuracy of the XV144 local oscillator isn't an issue.

The Kenwood DG-5 has already been mentioned.  That was the digital
display accessory that Kenwood made specifically for the TS-520.

You can get the manual, with schematic and block diagram, to see how
the DG-5 used **three** outputs from the TS-520 to accurately show the
frequency...those are the DET, VFO, and CARRIER RCA connections on the
back of the TS-520.

If you find a DG-5 for sale, make sure you get some sort of guarantee
that it works and is not intermittent.  The DG-5 was one of the most
unreliable devices made in the ham market in the 1970s and early 1980s.
But it was very nice when it worked.

Mine quite working almost 30 years ago.  Been dead ever since.  Very
common condition.

I forgot to cite the link to the manual:

I'm wondering if the unit will offer all features remotely (far end of 100'
coax) if I can enclose it in something weatherproof.   Will it require
additional power/control cable(s)?

thanks,
Oscar, WB5GCX

There are various ways to control the KAT500. We'll provide more
details on remote operation later.
