The TKR-850/851 voltage regulator “failures” are most often attributable to a design problem I tracked down a number of years ago after having two TKR-850’s intermittently lose audio (of course,

The Service Manual is on RB. The rear panel 15 pin Molex connector is for attaching an external (KES-4, etc) speaker. If the supplied jumpered male Molex is missing, the previous user had an external

They came off other PD526’s; how close the factory made them to 11.5”, and how accurately you can measure them after having been deformed by the tight bend radius on a 526, I can’t say. But I

It's only capable of 1024 points max. I think everything else I can set to your specs.

I measured the cable lengths and it's rg214 and it's approx 11.5 in for jumpers but they might be a hair over 11.5 inches. I'm not sure how critical the length is or how exact it must

You got the cables from me, and they are decidedly the correct cables. The four 11.5” cables go between cavities, the 12” cables go to the triple-female tee that I sent. It has to be something

Something I posted back in 2018 on another board Plug a local mic in and see if it will key up and send audio / tone.. If it keys up with no audio then Check IC 628 on the front board for 5VDC, it

OK Mike, I see you already had replies about the audio jumper on the big molex connector. It has been a couple of years since I had to program one but make sure you exit program mode before you test,

Just in case you are not a vet with the 850, is there a molex plug in the connector under the transmit coax connector? On my Kenwoods it has to be there with 2 pins jumpered for the speaker to work.

The first two plots are typical of each individual cavity. In this case the high side. The second two are with the two coupling loops in line on the 3 high side cavities minus the coupling tee. So I'm

<-- What is the exact model of this 850, is it a version 1 or version 2 repeater? - reason for asking is that there was a design issue with earlier V1's (floating inputs on the DSP chip), which caused

Oops, yes typo.? Should have been 433... I'm trying to get them programmed to local Amateur repeartes in the 441 to 444 MHz receive range with 446-449 matching 5 MHz offset TX. ron KA3JIJ

"The antennas that the repeater and my base station are connected to are literally right next to each other, so there should be no problems at all." That may have been the problem. May have blown the

Are you saying the busy light stays on regardless of whether you're transmitting a test signal? (i.e. all of the time?) If so, is there any audio being generated at the local speaker? Have

<-- Hi Mike:? Have you been able to "read" the repeater using the Kenwood programming software (i.e., to confirm he RX frequency)? Can you hear anything via the local speaker (you do need the

Got a TKR-850 that was abandoned at a tower site.. powers on and transmits fine (can transmit using CW ID button and getting 25w output) but receive appears deaf, Busy light is staying on and can't

Telewave makes a folded dipole that works very well.? I regularly drive by a California Highway Patrol office that has two on the tower. Here's the 45-54 MHz

I know this is a long shot, but does anyone have a pair of channel elements crystalled for 147.180 TX, 147.780 RX for the MSR-2000 they'd like to sell? I thought I'd check here before I order a set

A Victron Smart with a Victron SmartShunt right at the battery (such that the shunt only sees battery current and not load current) is a reasonable approach if you have lead-acid (flooded or AGM). See
