Nick,
I know you got many responses to your question about frequency calibration on
the K2.
I just wanted to give you my slant on this.
When I calibrated my K2, I set up the K2 as a counter. On the tip of the
counter jumper cable you built, wrap a little piece of bare wire around the
banana
Saw a article in FISTS news letter about mods for a K1, Changing USB to LSB,
Does any one have comments if this works and why do it ??.
Mod is remove RFC1 and jumper it, then realign BFO

In the article I believe Harry explains his reason for doing this. First note
that he is a
Bob,
I guess it is worth a try if you really want to do that. The BFO
frequency must change to the other side of the IF.
One reason I can see for changing USB to LSB is to change the pitch of
the received signal note as you tune upward in frequency. With USB, the
pitch decreases as you
I operate from the shores of the Chesapeake Bay in Virginia. The water there is
only moderately salty but corrosion is very rapid compared to my experience
with inland QTHs. I was wondering if this would be a problem for my equipment.
So far, no problem. I imagine anyone near the sea shores has
Thanks to K6DGW K6PJV, G3YMC, WB1HGA, K7UP, K6DGW and
others that responded to my query.
I suspect it is OTH radar, the suggestion of K6DGW.
Do a Goggle search using oth radar, lots of
interesting leads, including these:

Hi All,
Have just noticed that I'm hearing nothing through my K2/100 speaker.
Headphones work OK and fixed audio out is fine, but nothing on the speaker
or at the external speaker jack.
Would I be right in thinking that the headphone socket on the front panel
could be on the blink ??
Thanks
I live on the southern shore of Fidalgo Island where the fresh salt air turns
metal of most sorts into new colors. In order to minimize corrosion I have
come up with the following technique. After all the soldering and close
trimming is done on a project, I go back over every lead end and
Did you just build it? Has it worked before? There was a builders
alert that came out recently about changes in the jack.

Tom,
I recently repaired a K2 that had lived for several years in the salt
air of Houston Texas. The external case screws and the connectors on
the rear panel were corroded enough that they were changed. However,
the inside of the K2 still looked just fine.
If I can base any conclusions

It is possible that the push
to legislate use of CF is an attempt by the CF industry to cement
their
use before LED lighting reaches this stage.
Maybe, but I doubt it, because all the legislation I've heard of is
simply aimed
against conventional incandescents.

Can anyone tell me the design values for the termination impedances for both
the bandpass and lowpass circuits. I'd be ever so happy if it is 50 Ohms.

That is probably ood advice. I keep the equipment in a closed room, but I think
I will cover it. I generally keep my radios for a long time (this K2 is
replacing a Kenwood TS-930, bought in about 1980!).

This thread seems to have come around to an Elecraft issue again.
Running in parallel is a discussion about whether it's necessary to leave
equipment powered on in a marine environment to avoid corrosion. I've
serviced a lot of electronic equipment on ships and have seldom encountered

While it's likely most of us can afford the extra cost of leaving our
gear powered up to keep it dry, it doesn't sound like the right choice
for those who want to be good stewards for our planet.

Please. Only because of its own selfish need for carbon dioxide and human
waste products. And it frankly can get that from any number of sources. It
has no interest in me, personally.

Craig,
It's hard to believe, but I think you're actually serious.
I never dreamed the cunsumptive ugly American actually
exsisted beyond the minds of those of other less-consumptive
nations who -think- Americans are that way. Then you come

That is exactly why energy must be made expensive,
so people have to pay through the nose for it.
I vote for gas at $6.00 a gallon and a forty cent killowatt hour,
only then will people pay any attention and do something.

Unless you have good IDS connectors to stick the wires into, yes those
things are tricky.
Personally I prefer the straight across computer jumpers where
applicable and I use wirewrap for the rest, but for those who do not

Which filters are you referring to? If it is the K2, clearly the BPF's are
50 ohms in and out. It is not so clear about the LPF. It could be doing
some impedance transformation to match the output impedance of the amplifier
on different bands.

Can anyone tell me the
