#64 Collins KWM 1 Repair

In this video we take a look at a transmit problem with a KWM-1 amateur radio transceiver.

Young Players, please note:

1) Before touching an HV chassis Buddy waited until the supply had drained down to a safe level, this is important.

2) Buddy did all of his measurements using one hand, that way, if he touched something live, the shock wouldn't pass across his heart. This is also important.

3) Buddy has been doing this for a long time and he'll still be around for years, probably because he follows steps 1 & 2 

As for the final note about the screws, I must have worked for Collins in an earlier life. For as long as I can remember I have been tightening cross head screws until they formed a little 'X' at 45 degree angles then left them alone. Wood screws, machine screws, they all get that little 'X'.

Agreed. I really love working on these radios 

Yes, enjoyed it. 

So glad you sis. I also enjoyed doing it. Not every day you get to work on such classics as a Collins.

Seeing a post like this makes me very happy 

It does one good to see that folks notice these things that keep us safe. One slip and it's game over.
I try to be and show that I am safety conscious. Although I did make a mistake in this video on a particular step I performed.  I made another video today to show the correct way and currently editing it now.  Will be uploaded soon.
Thanks for the notice and pointing out safety here.

I agree. you must have been a Collins engineer in a past life.
