F/S Echo link cable from RC 210 controller
Good evening, as I go through and upgrade my repeater system, I have a NOMIC sound card interface from West Mountain radio and the cable going from the RC 210 computer controller to that interface along with the USB cable from the interface to the computer. All works well, just upgraded so this is now available for sale. If anyone is interested I will ship for $60 for the pair. This is all ready to go just plug in play into the controller and the PC. I also have a second NOMIC that I was using on a CAT 260 controller but this unit does not have any cabling with it. Just the interface box itself. I will ship that one for $35.

MFJ1112 DC power strip
2
Good evening all, about a week ago or maybe a little more I listed on here that I had a DC power bus for sale, it was the MFJ 1112 with six pairs of binding posts. That one has been sold, but another one has now come available from my repeater cabinet. There was another fellow interested W think his name was Robert. If that person was Robert and was interested, let me know because I have the one now available and dad has a 2 foot power cable because I'm modified it slightly the fit in my cabinet. I will get pictures of it and have those available. I will ship for $30. Oh, I should also mention that it has an Anderson power pole on the end of the power cable. Thanks and 73, Chad WI9HF Chad Nelson WI9HF/WRPL979 Janesville Wisconsin 608-754-8671 Send from my spectrum iPhone 16.

I have a low uhf micor mobile (old board) according to the manual. it did not have a decode board in it when I got it. i put one in it and did the mod to the board to bot key the exciter at all times. I must be missing a step somewhere because it will not transmit pl. receives pl just fine. Any thoughts?

Placing Two Identical Regulated DC supplies in Parallel
23
Any what to look out for situations for this, besides matching voltages? I took an Astron SS-30M that was not switched on and back fed 5-18VDC from a metered regulated bench supply to it. With initial switch on at 13.8V from the bench supply, the "on" current was 200mA that soon dropped to 10mA. The volt meter on the SS-30M then read 13.8V. SS-30M analog amp meter still at zero to the eye. From that test , it appears that no isolating diodes from SS-30 power supplies to common output would be required, and as long as the output voltages are equal, both supplies should carry half of the required current. It seems it would be best would be to use SS-30M supplies so the equal current draws can be confirmed visually, but not really necessary if equal voltages stay equal. If available, is it significantly important or just preferred to connect both supplies voltage sensing leads? The SS-30 supplies do not have externally reachable sense wires, but if really needed, they could be brought outside the case. John

Schematic needed, Motorola NU-140 power supply
Greetings, I'm looking for a copy of the NU-140 power supply. This is the 110 AC supply used on the P series 5 Watt high band (10 Watt low band) P33 Handie Talkie. I have the schematic of the later version (NPN6013A) but resistor values and capacitors don't match the supply I'm repairing. Thanks! Wally Gibbons, AF7FH North Logan, Utah

Zetron 48-JR Shematic and RX Audio
4
Hi to All, I have a Zetron 48-JR with a receive audio problem and was wondering if a members has the schematic of this contr?ler? On the R-B web site I could only find the brochure and installation manual. The parts list is there but no schematic or board d¨¦tail like other Zetron manual? My problem is when your turn On the contr?ler it work's but the audio is a bit degraded. With the time passing the audio get more and more degraded to a point that the contr?ler do not decode CTCSS and DCS no more. This time is very short, a few minutes at the most from the trurn On and the time it does not work any more. Has anybody sean this problem before? Nice Easter Holiday to All. Best 73 Carl VA2CMB

Running echo link on a repeater
4
Hi, does anyone have any good resources? Other than echo Link to help me set levels for box on a repeat running echo Link? I do it by trial and error because I've never found a good resource to help me set that correctly, people say I'm cutting out all the time and people coming through my link for Peter seem to cut out a lot. I am going to get a West mountain radio rig blaster plug-in play next week which will maybe help that problem. But in the meantime, does anyone have any settings? Suggestions for my echo link note?

Manual CDM Low-Band
8
Hi to All, I just bought a nice Motorola CDM-1250 Low-Band modified for 6 Meter Ham Band. But I am looking for the Service manual and I can only find the manual for VHF and UHF. The radio does work and turn on by the ignition accessories plug pin but I have some problem with the control head. No ON-Off button function, no Lights for the display, no RX-TX light, no Lightening of the DTMF Mike. And I have some question on the output power specs of this radio, it is set to 65 Watts in CPS put putting out 90 W on my Bird Bench Wattmeter? My Model is : AAM25DKD9AA2AN I am hoping that a member as seen this control heads problem before and somebody as the proper manual for this radio. Or at least the model number info to know what is the normal output power of this radio? Thanks¡¯ to all for looking in their electronic document file. Best 73 Carl VA2CMB

Tuning Rod for Wacom WP-643
8
Good evening, I was recently asked to tune a Wacom WP-643 duplexer. I was having a hard time getting the pass set on one side; I couldn¡¯t seem to manage to tighten the locknut without the tuning rod turning. None of the other cavities gave me any unusual problems. I finally figured out that the Invar tuning rod had been bent slightly and it was making the threads bind. I finally managed to get it tightened to the sweet spot and all is right with the world. But it got me wondering about replacement rods. I know Wacom is gone, but has anyone sourced tuning rods for Wacom duplexers? I assume the rod attaches to a plunger similar to the DB4060 (I¡¯ve never had a Wacom duplexer apart), so even if a new rod was available, the old rod would have to unscrew down through the top of the cavity rather than out the top. That would probably be difficult given the bend in the rod, but I assume I could screw the rod up beyond the bend, cut it, and then screw it back down and out the bottom. At any rate, this is mostly an academic exercise since I did manage to get the pass set properly. Thanks for your thoughts. 73, Mike WM4B

In search of dB4060 -005 coupling loops or assemblies
8
Kevin has given me a lot of help tuning the overpainted and unknown dB4060 diplexer. It is smelling a lot like they are not the ham band model. If anyone has up to date contact info on the firm called duplexerrepair.com I would greatly appreciate it. If anyone has extra -005 coupling assemblies, please let me know, off list.

DB4060 Series Dfor a 4-cuplexer Cans
7
Wrong. The loops are different between high-pass and low-pass. And, the loops are different depending on bandsplit. If you don't have the right loops, or are using the loops for the wrong response (high-pass versus low-pass) you probably won't even make rated space for notch depth. If they are correct for the bandsplit and pass response you'll get 85 dB for a 4-cavity DB4060. --- Jeff WN3A

KSG-4500
I procured a Kenwood KSG-4500 repeater. I think it may have a narrowband kit installed. What should I look for internally to check? I see references online to the Z-kit but not to the installation instructions. This unit seems to use some common componment to the TKR-820.

Be on the lookout

Motorola VHF Quantar SN 509CLR1418 stolen from site last Thursday... Along with DB4060B ...missing mounting brackets. Both tuned to 146.36/96 pair they cut the tie wraps holding the 4 cans together..the brackets had been misplaced but found and were to be reinstalled when repeater was discovered missing Also cables from rptr to duplexer and duplexer to Heliax gone....Sinclair Duplexer in cabinet that the rptr was sitting on not touched nor a UHF MII repeater...so this was personal....and I have 4 suspects in the list. Sheriff's office has been contacted. Contacting Boone Co Iowa (ironic) where the duplexer was bought from to get the SN on both units bought..lost the paperwork Chris WB5ITT

Swap: Ics controllers quantar 1x for a northcomm quantar ecm.
10
Looking to swap a brand new ics control quantar 1x for the northcomm quantar ecm and program cable. I'm looking for a more simple plug and play solution than something I need to jump through all sorts of gyration to get up and running. And I don't need all the capabilities of the ics I just need remote disable, and courtesy beep. So the northcomm might be better for me and the ics might be suited to someone who has more patience than i do to set it up properly and needs the advanced functionality of the ics. I'm only using this on a gmrs repeater so I don't need a bunch of advanced features or digital linking. My understanding is the northcomm is just set wildcards in quantar and then 1 adjustment on the board that requires no test gear to set it up. Suffice to say I can't get courtesy beep or remote disable to function on my quantar with the ics and the ics is brand new. I got voice id'er to work fine so I'm sure it's a setting on the ics board. I'm just out of patience to screw with it. I want an overall plug and play unit. I will also sell the ics outright for what i paid for it in leu of a swap. Let me be clear it's not ics fault it's l something I'm not doing correctly and I don't have the eyesight or dexterity in my hands anymore to work with small stuff like this board. Thanks Robert Chrysafis Kc8gpd Wrcm325 Scottsbluff NE
