Quantar running on batter
I have been trying to get my repeater to work on DC power but I think I'm doing something wrong, or have a wrong setting.? The repeater works fine on AC.? 900mhz with a tln3259A power supply, with the cables on it to connect to the DC system.? ?When I apply 24+ volts to it, I can not get it to power on.? Am I missing a setting in the CPS software or is there something else I need to do?? ?The repeater powers fine from AC.
Thank you

Re: Quantar Extender Cables
I like to use the curved or straight pick from the Harbor Freight pick set, depending on which one I grab. If the SCM card is being stubborn I've had it bend the tool on the back of the front panel.

Re: Quantar Extender Cables
The cover plate is a board puller, FYI.
?
There's a metal tab on the backside of the board cover faceplate (the one with the Speaker).? If you turn it around, you can slip it in to a groove at the bottom front underside of the SCM and WL PCBs.? By firmly grasping the hooked faceplate, you can get enough grip to pull the board straight out from it's socket.? Don't try to lever or bend it, just pull straight out.
?
Captive metal levers like the old minicomputers had would have been better, but this is a decent have-it-in-hand solution.? You can almost get enough grip on the board to pull it with your fingers as-is, but there is really no good spot to grip it from.? This hook solves the grip issue.

Re: Antenna Thoughts and Suggestions
That's strange, I often get better coverage than it gives, and rarely (I don't remember a case) don't get it where it says.?? Make sure both antennas are entered correctly (it defaults to mobile coverage at 2 meters height), and I always lower RX sens to .25?? And I have used it on hundreds of locations ... counting both ends.??? Wished it had a little better resolution and sometimes the map is off a block at a distance (sometimes at a distance it paints the hilltop coverage off a little). I consider it accurate, especially for the money.

Re: Antenna Thoughts and Suggestions
开云体育I have found Radio Mobile to be quite accurate. As I recall, there are certain parameters that need to be set in order to get that accuracy. Haven't used it in years, however. It did compare well to the software used by a local GE/Harris/Kenwood dealer who spent considerable $$$ for his software.Chuck WB2EDV On 4/1/2025 5:43 AM, wotan398 via

Re: Antenna Thoughts and Suggestions
Hi, Radio Mobile is a toy... Send me the coordinates and tx, antenna, cables etc parameters and I will try a real coverage simulation? with the ATDI's ICS Telecom professional tool. I think there are 50 meters resolution DTM data for the USA on the web. (DTED 1 or 0 at least). The result will be in GE kmz format and can be seen on regular GE maps.

Re: Antenna Thoughts and Suggestions
This evening, once again, I tried Radio Mobile. I tried it a few years ago at the request of the frequency coordinator in eastern Idaho. And again this evening with similar results. If only I had the coverage it shows. It is nothing close to what I really have. It shows coverage way far out from what it really is. Maybe it is close in the flat lands, but sure isn't here in the mountains.

Re: TPL PA6-1AE UHF amp
To the best of my knowledge, the 751/851 production was close in alignment to the 750/850 version 2. I'll defer to others here who own/operate/run Kenwood shops. Jeremy K1LFK On Mon, Mar 31, 2025, 5:52?PM Chad Nelson via <chad.nelson71=[email protected]> wrote:

Re: TPL PA6-1AE UHF amp
开云体育Thanks, Jeremy that's good to know. I mentioned it to my radio guy. He didn't know much about the 851, so maybe that shop to deal with many of those. Do you know how oldthose radios are approximately? I'm talking about the manufacture dates of the TKR 851?Chad Nelson WI9HF/WRPL979 Janesville Wisconsin 608-754-8671 Send from my spectrum iPhone 16.

Re: TPL PA6-1AE UHF amp
With the TKR-851 being designed for 1-25w operation, that's probably your best candidate for this application. I have two of them set aside here for future projects that require an external PA.? Jeremy K1LFK? On Mon, Mar 31, 2025, 5:31?PM Chad Nelson via <chad.nelson71=[email protected]> wrote:

Re: TPL PA6-1AE UHF amp
Chad,
If your TKR-850 is a Version 2 radio, the output should be stable at 5 watts in the low power setting. I have ran them as low as 1 watt and never had a problem.
?
The early radios prior to the Version 2 series did have PA issues, but many of those were updated with a new PA deck under a Service Bulletin procedure by Kenwood.

Re: THREAT TO 222-225MHz Spectrum
Consider this is a test of our resolve by those who stand to gain financial gain from the selling of the spectrum.? They will infringe on the known spectrum of radio amateurs to see how many squawk and file paperwork with their regional FCC Field office and then with the FCC HQ.? If the noise is weak to moderate, they move forward with their intended agenda to confiscate that particular section of spectrum at a very advantageous price.? Get busy writing to your Regional Field Office and the National HQ of the FCC and demand the protection of our spectrum that is used for a public service of backup communications.
