[Premium-Rx] Off-topic: Marconi H1541 HF Drive

[Chuck Urmson]

Hi Everyone,

Let me try this again:  Does anyone have any information on the Marconi 
H1541 HF Drive?  Schematics or manual would be ideal but even the 
back-panel connector pin-outs would be a great help. 

I have one which seems to work fine but when I change frequency it hangs 
on "Tx. Tuning" presumably waiting for a signal back from the matching 
transmitter. 

Thanks in advance,
