Hello to the group. Can anyone tell me about the purpose of the "Secur-it" board. I have checked my different manuals, and I can't find any data or a description of operation. I'm just curious.

Even though it is a Motorola inside, it has its own vertex software and cable.? Overall I recall it was a crippled XPR with a limited feature set Jerry

I don't typically use the term "desense" in a standalone manner to describe the above. I might say "desensed by another TX". To me, simply saying "desense" is shorthand for "self desense".

I had a similar noise on VHF. You could hear it in various places. It ended up being a commercial wireless internet providers new site. It provided about 6 to 8 db of site noise from 138 to 158 mhz.

If they're abducting aliens then they got the right guy. 73, Gary

I wonder what the aliens would do, if we told them, "Keep Him! We don't want him back!" <Evil Laugh> Sent via the Samsung Galaxy Note10+ 5G, an AT&T 5G smartphone

One idea.... look at your 3rd harmonic on 443.970.?? A local T-hunter taught me that trick. Around here the ham radio transmitter hunters use 146.565 MHz, and in addition to that you will find the

THanks Jeff, the list of possibilities that you are giving me makes a lot of sense. I will have to take my large snow boot and small shovel, to go back to the site. Only a 100 foot shoveling if there

Alien abduction?? If so, they'll probably be trying to sending him back? pronto..... Joe

Yes I tend to put too much detail so I don't have to answer too many questions. To make it short, could it be possible that when a sinclair Q3220E duplexer when put vertically all is working ok. And

The tuning of many duplexers will change juuuuuuuust a tad when rotated from vertical to horizontal due to the position of the center conductor flexing slightly. Some, but not all, cavity resonators

Your message is a little hard to follow when you talk about "duplexer face down" and "facing normally". Much easier to understand if it is vertical or horizontal. The easiest way to find out would be

I have a UHF site where out of nowhere I have a lot of problems with reception. When I built the repeater I had great performance on receive and the tx was right where I wanted. I use a pair of

I don't post here very often, but in MY opinion and repeater that works properly is a good repeater.?They ALL have pros and cons that change depending on the use, and environmental

Aaron, I totally agree with you, we need the inputs from everybody. All have great contributions, even my occasional long wacky ones. It is up to each of us as readers to learn what we can, and

Just so you all know ... This thread has gone on wayyyyy to long Don

Hey guys. To add to all this, I have 5 Kenwood repeaters in service, and I'll say this, they just work. I have 3 Kenwood version 1s, and 2 version 2s, and they take a beating every day, just look at

Tree limb touching a power line, or a failed insulator on the power line, is a likely culprit here. ?After listening to the YouTube videos, that sounds like a high voltage arc erupting somewhere

as a ... Not trying to pick a fight, but wouldn't you consider a repeater receiver being overloaded by some other transmitter's fundamental to be desense? I would... appropriate to Then there's the
