[NLRS] Getting onto 5760 MHz

[W0ZQ at aol.com]

Hello John.  Excellent news on the 5760  station !   Regarding the TR751A, 
there may be two modifications that  you may wish to think about.

1)  The stock TR-751A is 25 watts or 3  watts out using the HI/LO button.  By 
opening up the rig and lifting a two  pin connector, this disables the HI/LO 
switch thus preventing you from doing  something dumb.   You can set the drive 
for whatever it is that is  needed and then forget about it.  

2)  I have modified my  TR-751A to inject +9 vdc on the RF out put line and 
then modify the DEMI  transverter to use its PTT-H.  This eliminates the 
"extra" PTT control  line as PTT is completed over the IF coax line.   Its an easy 
mod that  requires brief surgery on both the TR-751 and the 5760 transverter.   
 You can still use the TR-751A for other applications if you so wish.

It  would be easier for me to do these mod's for you rather than to explain 
how to  do them.  If you want, you can give me your TR-751 & transverter and  
I'll make the mod's for you ... it will only take an hour.   You can  still add 
the power amp yourself as you have discussed .... I know little about  that.

73, Jon
