[TenTec] RE: 6 meter transverter

[Simmons, Reid W]

Jay;

I built one when they first started shipping them in November '94.  My 
unit had no parts missing but it did have a few extra.  The only problem 
with the circuit I had was with a Zener diode that was getting way too 
hot (could not keep ones finger on it very long).  I calculated a new 
value of resistance for the circuit, put that in, and everything was 
fine.  I informed Ten Tec of the problem and they confirmed that it was 
indeed overheating.  I am not sure if they made any changes to the 
circuit (different resistor, or higher wattage Zener) of future kits.  I 
don't have my notes with me, but if you are interested in the 
modification let me know and I will get it to you.

ALSO, if you are planning on using it with your OMNI VI, put some 
procedure in place to remind yourself to turn the power output down.  I 
have on two occasions now put a full 100 watts into my 1208.  The first 
time it blew out some switching diodes which Ten Tec said needed to be 
replaced anyway with a higher voltage type.  The second time (that was 
only a couple of months ago), it heated up the resistors that make up 
the power attenuator to the point where I could smell them.  However, 
nothing needed replacing - as far as I have been able to tell.

73.

Reid, K7YX

Hello Everyone,

I'll gonna start building a 1208 (believe that's the model number) 20 mtr.
to 6 
mtr. transverter kit this evening. Anyone run into any problems during 
construction of this unit? I did have a few parts missing but no big deal.

Thanx,
