Hey folks- we recently acquired several crescend dxv100-10 VHF amplifiers. We¡¯d like to perhaps use these on our repeaters BUT cannot find documentation on them. Spoke to Crescend and they said, ¡°we don¡¯t support that product¡± and when pressed further as to whether they could search their archives, the response was, ¡°We dont have an archive¡±¡ª- So yea, not really helpful. Perhaps someone on the forum here might be able to provide some insight/documentation on these units? Much Appreciated! Bryan, KB9UZO

I have an issue with tuning a duplexer. As you can see from the pictures the high pass looks good but the low pass has a double peak. I am having an issue trying to merge that double peak into one peak. Any suggestions? Do I have an issue with a high side can or do I just need to keep at it? Thanks Robert

Motorola SLR5700 DMR Repeater
3
My Motorola SLR5700 repeater goes into transmit every minute and does a 5 second data burst. Here are the settings I have in my repeater, I never recall having this problem in the past. Are my settings wrong? Any help is appreciated. We are on Brandmeister Server Master 3102. The repeater is currently on test bench in a dummy load. Beacon duration 4320, beacon interval 60 Or perhaps there is a different setting I should be paying attention to? Thanks, Joe N4ADI

Need help on the Quantar test microphone
3
I received an email this morning from a Civil Air Patrol group. They have a Quantar and discovered that the test microphone jack on the front of a Quantar is a 6 pin! RJ11 / RJ-12 / RJ-14 style socket, NOT an 8-pin RJ-45 style. The Quantar (and MSF5000) test microphone is an HMN1001A or HMN1001B, and is a regular mobile microphone except with a 6-pin plug on the end of the curly-cord. Does anyone have the info sheet (even a PDF) that was packed with the HMN1001? Or the part number for the part number for the HMN1001 replacement microphone cord? I called Motorola Parts-ID and WisComm this morning and neither has the info. Does anyone have a contact inside CAP communications??? Maybe they have that info. Thanks in advance. Once I have that part number I'll call Parts-ID and check availability get a price and I'll add both to the Quantar and the MSF pages at repeater-builder. Mike WA6ILQ

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.

THREAT TO 222-225MHz Spectrum power point presentation for 220 Spectrum Management Association (Southern California) coming your way.
2
If you think this only affects Southern California please view the attached Power Point that will be presented during our Quarterly Zoom Meeting for our Coordination Group, the company causing harmful interference has a new license for Indiana, so no longer in Los Angeles they have licenses in Arizona and Indiana. Please educate and understand they intend to do testing at various locations across the US, that testing will impact Radio Amateur operations on the 222-225 MHz Spectrum. If you are a 222MHz Repeater Owner and would like to be a guest during our quarterly meeting of 220SMA where the attached power point will be presented, send me a message and I'll forward you the Zoom information. No one will fight for our spectrum but us, if they are successful which band is next? 1.2GHz, 440MHz, 2 meters?

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

Mirage 3016B F/S

Hi all, Anyone want a project? I have a Mirage 3016B 2m 170W amp for parts/not working for sale as-is. It is in great cosmetic shape, but when powered up, the lights come on, but the amp doesn¡¯t activate when RF is applied. I do not have any test gear to speak of and electronic items don¡¯t like me when I take them apart. I will ship for $125.00. Thanks, Chad

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?

Difficulty Programming a Maxtrac 300, 32 Channel
12
New to the group and hope you guys can help out in this. I had a real old laptop an Inpiron 3200 that took a crap and it had the RSS software on it. Fortunately, I had made a copy of the RSS on my other computer and I am able to run it in DOSBox but cannot communicate with the rig. The computer I am using only has a USB connector to which I plugged in a USB to serial cable, this went to my RIB box and from there onto the rig. However, communicating with the rig fails. I was wondering if the 300 has a specific Com port and baud rate settings that I could change on this computer to get communication moving along. Thanks, Bill K2WH
