[600MRG] TDD-5

[Rudy Severns]

I've been keeping my head down with other projects but the report on FCC
activity has got me moving again.  I was recently given a TDD-5 MF
transmitter in very good shape, very little diddling or mods as far as I can
tell. I went to the usual sites (BAMA, etc.) but haven't been able to find a
manual.  I did find a note on converting a TDD-5 to 40m but no schematic.
I'm sure I can buy a manual but I thought I'd ask the gang first if anyone
has a schematic or could point me to one?

 

My 630m transmitting antenna can be retuned to work on 2200m by adding a
loading coil which I just happen to have.  I think I can get an efficiency
better than 1%, whoopee!  This summer I'll set it up so it can be switched
between 630m and 2200m from the shack.  I'm also hard at work on better
receiving antennas, particularly terminated loop arrays.  Lots of fun!
