[MRCA] [Milsurplus] Strong Stomach Needed.

Hi Dennis,

Nope. Didn't have to replace any resistors.

I got the ATD with a few stupid modifications, that I couldn't figure  
out why they were done. The way I got it, it managed to put out about  
4 W on CW.
After I removed the modifications and restored the PA circuit to  
normal (nothing was missing, just some extra components were added by  
the hacker), it put out the specified 40 W without having anything  
further to do. Oh, yes, the original Rajah antenna connectors were  
missing and a UHF type connector was there instead, and a BNC  
connector for the receiver antenna.
I removed those, and Mike Hanz supplied me with replacement Rajah  
connectors, everything is back to stock. I found a NOS original  
dynamotor for it, bought the appropriate plugs and made up the cables  
so the only non-stock items in the setup are the Vinyl jacketed  
multiconductor cables themselves.

The ARB/ATD setup is working great and I'm running it with a 35 A 24  
VDC surplus Lambda switching power supply. Incidentally, the supply is  
completely RFI-free.
The next thing is to set up the LM-18 after making up the ARB - to -LM  
cable with the appropriate plugs.
