Sure thing, Alex!
The attenuator switches in and out with a latching relay and the preamp too,
so it's cycling one click one click two clicks almost simultaniously. Is
there any effect noticeable while pressing the button?

The selectable sidetone source is for support of older K2s that have not had

One's never to old to learn... I didn't know this and just cheked it. That

Maybe something to put in the Troubleshooting FAQ on the Elecraft website?

Hey folks,
The new-to-me K1 arrived on Saturday. I was swamped with other tasks

I had previously supposed the K1 was today's HW-9. Boy was I wrong.

Peter,
Well, if you hear sidetone, you got it right!!! It is no more complex than
that, and there should be no uncertainty in your mind.
The real problem is that folks don't know where to look first if the
sidetone suddenly disappears.

Dale,
You are correct that batteries provide a good stable source of power. Just
remember that they can pack a lot of current, and they do not protect
against a short circuit condition like a power supply will - if the battery
terminals are shorted they can provide enough current to melt

Be careful buying older Tek scopes. Many of the repair parts are not

scopes but many of the parts were proprietary made custom for Tek or in the

Hi
In interesting piece of trivia. The DM44 sensor in the temperature probe is
a 2n transistor. The circuit is similar to the temperature measuring

Yes, but in actuality, you can very often pick up a good 465 or 475 for
$100 or so, take it home, clean it up, and it will work for you for
years. That's hard to beat. 73 de Alex NS6Y.
