Re: UHF Repeater Input Frequency Issues
Hi
I can tell you that a 4 can duplexer does not provide enough rejection for 100 watts. Six cans of BpBr are needed with higher power above 40 watts.
That's why these small mobile duplexers with six

Re: TPL PA6-1AE UHF amp
Chad,
The easiest solution by far is an external power attenuator between the TPL amplifier and your transmitter to reduce power. This is a bolt on, or rather thread-on option that works

Re: DR-2X Failure to Switch to DC
See post 211955, if you break the DC lines with a high current 120VAC relay then you don’t have to remove any fuse or worry about the charger inducing noise. The battery will charge when AC is

Re: DR-2X Failure to Switch to DC
Jim,
You might know off the top of your head, in reference to the F6001 (1 amp ) fuse. If you were to pull this fuse from the circuit, #1 it should "disconnect" the internal battery charger circuit

Re: Tektronix Y400 vs Anritsu Cell Master
Thanks for the insight on this and the detailed comparison. I ended up buying an HP8921A but will consider the Tektronix or Anritsu down the road as a more portable option. Thanks again.
