Just trying to have the output match the sensitivity of the input.? The input makes it miles and miles farther out when just running the repeater barefoot.? About 100 gets it to parity based on a

This is great information.? We have a few cavities around that may have been exactly for this at one time or another.? Will look into it.

It really sounds like water in the feedline issue. Fiberglass antennas are not for repeater use…but we do what we have to. Fiberglass bends with the winds and creates micro-cracks over

4 cans aren’t going to do it. Why all the power hungry? Turn drive down and enjoy it.

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

I'm sorry, correction.? Input is 447.900.

Hello from Michigan! I'm wondering if some folks have an idea of what might be going on here. Equipment: Yaesu DR-2X Glenayre 97 series 250W UHF amp Glenayre 2728 PSU Sinclair preamp with a PA8075

An attenuator something like this one may be easier....?? use your existing 5w input amp... https://www.ebay.com/itm/274310391083 I have no idea who this guy is, I'm just using his auction as

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

Remember guys that it's not just us hams that may be interfered with either. Up here in Oregon the 217 to 219 MHz range is heavily used by the Electric power company for Their Tier II capacty plus

Yes Mike pulled me head out of my rear end with his answer. The 120VAC coil would go between battery output and the repeater (either plug or hard wire config on your repeater), all it is doing is not

Does the repeater still work on AC supply? I ask because there's another failure condition which requires power cycling the RX and TX chassis's with a external FTM-400 control head. I had one on the

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

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

Hey joe thanks for that, I'll have my radio shop guy maybe take a look at it and see what wecan do. I don't dare go in there because I'm blind and I don't know what I'm looking for. Chad Nelson

Chad, From what I see in the manual, it says 1-6 watts input for 70-100 watts output. https://www.repeater-builder.com/other-mfrs/pdfs/tpl-pa6-1ae-1be-1fe.pdf My experience with various TPL amps is

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.

Thank you.? I will have check that.? Not familiar with Motorola or most repeaters in general and have never had to program one to use a battery, but that explains why.? ?Just need to get my old
