Yes, I have started doing a bit more radio again, let's see how long this lasts, as I need to de-clutter a lot.
Some time ago I got a box with a few CB radios, totally for free.
4 radios in different states, and all FM rigs.
First one (40 channels) tested worked in TX and RX. Power on and 3.5W TX output.
Second one (40 ch) had no TX output (nominal 4W) I had found that before, so not such a surprise
Third one (40ch) had about 2.8W out, and needed an external speaker to receive.
The last one was a 23 channel FM rig with 700mW out (nominal 500mW), b
I could probably find a replacement for the blown final transistor in #2.
All sets had, to my ear, poor sensitivity of about 2uV (-100dBm) for a well readable tone.
All worked on receive. #4 had poor audio., probably a defective electrolytic capacitor.
I think all those radios could use an alignment
Are any of those radios useful for anything ham related? In my view, yes.
- one or more could be used as a monitor receiver on 27MHz, for propagation monitoring (maybe a good use for the one with the blown final.)
- one could be modified and used for monitoring or transceive on 29MHz FM. I already have such a rig, so not so likely.
- I could use the casing of those radios, and build some home construction transceiver or receiver. The channel switch could be replaced with an optical encoder, and the squelch/volume pots for volume (duh!) and RIT control.
I have been thinking of some simple low power transceiver projects.
Anyone with other ideas?
