Thanks, Joanne I agree Chad Nelson WI9HF/WRPL979 Janesville Wisconsin 608-754-8671 Send from my spectrum iPhone 16.

I have a few of these LMM 220 amplifiers. I drive it with .05w and it gives me 113W or so output. From the analyzer it looks very clean. Of course these amps were not made for FM. I have seen a few

Chad, I think you have made the correct decision. Glad Ken chimed in also. Ken is a Kenwood dealer and also sold TPL amps back in the day. I have purchased several TKR-750 and 850's from him and a

That would work too but the only time that connection is absolutely necessary is when uploading firmware to the repeater (same as the TKRs). Otherwise, the DB25 on the back panel is fine (straight

Hello everyone Question regarding a NXR810 repeater, What cables & software are needed to reprogram the repeater, also dose Kenwood use an interface box like the older Motorola rib box?.

Nice clean work there. I'll make a suggestion, and it's not specific to this project, but one of those "makes perfect sense" things that applies in many cases where you have high-level RF through

About 3 years back I had one DB4332-B UHF low pass filer but needed two, so decided to reverse engineer it and build a clone. The variable piston capacitors are Johanson 0.8 - 10Pf rated at 150V. Back

Not a problem with 100w into the cable and only 30w dissipated over 18ft of RG-142, and the connectors would be usually be heatsinked to a chassis of some sort anyway. Belden RG-142 is rated up to

Unlike the CATV world, where splitters are common and a splitter can have a variety of different drop/tap levels, splitters are not as frequently used, and when they are, the are usually referred to

That loss is dissipated as heat. You may have issues if the connectors are soldered on. Glenn WB4UIV -- ----------------------------------------------------------------------- Glenn Little

Mike: Thank you for your emails. I agree it would be great if the capacitors at 850 Mhz were adjusted to something less than half of their range, I could just install the same size coils as in the

Once you know current and needed capacitance you could probably pad the originals with a fixed value silver mica.

For a similar performing filter the inductance and capacitance would be about double if you cut the frequency in half. Question is, will the original capacitors adjust to about double the capacitance

A preselector is simply a band pass filter. A splitter is….. a splitter. Matt AL0R Sent: Thursday, April 3, 2025 18:21 To: repeater-builder@groups.io Subject: Re: [repeater-builder] UHF
