The CCrane radios...
|
| |
I have three of them. They are really disappointing to tell the truth
and I think someone could make a good cottage business building a GOOD
AM set for the few people that really want them BCB only means no
bandswitch which was the bane of analog comm radios.

Any idea what the sensitivity of an AK-55 was originally?
|
| |
I've been working on a chassis, and it seems to be quite good now for a TRF. I've measured it down to ~30uV for a listenable signal (I can get down to ~20uV with a 400 Hz test tone). I can't say whether the impedence is matched between my sig gen (a nice Agilent) and the antenna input of the radio. This... more »

Had always wanted one to round out my small collection of TV's
