Hi, I own a MTR2000 UHF Low Band High Power. Apparently there is a way to get this low band within the ham band (430-440). I once saw a description on the repeater-builder website but can't find anything about it anymore. Is there anyone who can help me on my way? Thanks in advance, Manu - ON7FQ

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

Good afternoon everyone, I bought this on eBay as it says in the link below, but as it turns out, I won't need this so if anyone needs it, I sell for $10 It's brand new in the package and never opened > https://www.ebay.com/itm/185753551768?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=tbBinouRQq-&sssrc=4429486&ssuid=GWF0AxjSQFG&var=&widget_ver=artemis&media=EMAIL > > Chad Nelson WI9HF/WRPL979 > Janesville Wisconsin > 608-754-8671 > Send from my spectrum iPhone 16.

Have two Kintronic isocouplers VHF FMC-0, large style. Came out of service working when tower was converted. Those folks on an AM "hot" tower know what these are. Free for shipping costs, estimate $60 each to ship inside the US. Contact me directly if interested. Chris - KC4CMR

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

Hi, I hope someone can help me figure out an issue. I am trying to use a West Mountain Radio Rigblaster plug and play sound card interface to run echolink. The issue I am running into is that I use JAWS a screenreader that reads text outloud from the computer since I am totally blind. When I have my nomic working JAWS talks fine and everything is happy but when I connect the plug and play, I get the usual computer sounds out of my speaker, but JAWS doesn’t talk, (so I can’t do anything if it doesn’t read to me what is on eht screen). Does anyone have any ideas or how to make an external sound card play nice together with the internal one. I would be happy to use the internal card for JAWS, and use the USB card to run the plug and play, but I run into the same issue with the USB sound card. Thanks, Chad

I'm trying to figure out why our mtr2000 isn't passing any audio. We're using an external repeater controller through the wireline connector. This is new to us, and we're trying to get things set up before we go to the site. Before I try too hard and break something... Is that 4 pin connector (J6) supposed to come off? How do I release the wires? I tried pushing into one of the small holes, figuring that would release a clamp. The wires aren't budging. Thanks. Don

I am seeking advice where the RF feedline grounding/lightning arrestor block should be mounted to. I'm working on a project where the ham station is in the mezzanine of a warehouse where the tower was installed on TOP of the roof, with a seriously over-engineered mount in the middle of the building metal structure. The entire building has a ground rod ring around it that are connected to a 6" copper strap that does not NOT contact to the building. Near the coax entry point there is a building structural I-beam. The copper ground strap comes up along the outside side of the building, galvanically isolated, through a plastic tube and junction box, into the shack. So, for best lightning/EMP protection: 1. should the ground strap be sandwiched between the building i-beam and the ground block, or, 2. should the ground block be connected to the copper strap secured by some kind of isolating material from the metal building? If typing words is not your forte'; email direct for my cell number. Benjamin, KB9LFZ

Good morning, This question is for all the 220 MHz repeater owners on the list. We have a 25W repeater and would like to add an amplifier as it hears much better than its transmit coverage. Our exciter output is variable from 1 to 25 Watts. Our antenna is a DB224-JJ. What type of amplifier are you using? I’m really looking for options other than Henry and TE Systems but not seeing very many. James Adkins, KB0NHX Repeater Trustee - Nixa Amateur Radio Club, Inc (K0NXA) www.nixahams.net

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.

I've got a TB8100 in GMRS service. I want to of course provide proper ID, but as I share the channel with another system, I do not want the ID to beacon, just politely properly ID routinely after use of the system. In the CWID System tab, pretty sure I do not want Automatic CWID checked - but ID after some period of local system use would be done via a Task Manager configuration? Examples, screen shots welcome.

Hello all, would anyone have any tuning information on the Varden duplexer 146-148mhz. I know its a long shot, but no searches on the web produced any results. These were made by Varden Electronics Box 791, Jackson, Michigan 49204 Thanks for any information

I recently had the need to do some research on Helper Instruments and locate a schematic. I ended up overhauling the page at Repeater-Builder. Does anyone know what Bill Detweiler's ham callsign was? It's undoubtedly been reissued... Neither the ARRL or the RCA have that... Does anyone know who the rest of the Helper people were? Or what happened to them? Maybe you have an old business card in the back of a desk drawer? If anyone has the missing applications notes it would be nice if we could offer them for download. If all you have is a paper copy we'd be happy to scan it and return it.
