I have a programming cable I used to program a low power dash mount astro spectra. I have read that this cable is usable for programming a high power trunk mount astro spectra. I'm not sure about the (B+) power cabling. Do I need to connect the heavy gauge vehicle battery cable (high power battery cable) to the spectra and NOT use the small gauge (fused) wire on the low power programming cable. Will the astro 25 tuner ver. 5.04.00 program my astro spectra? I only require analog NB. No frills I appreciate any guidance. Tim AE7TH Vashon Is. Wa.

can anyone help with this I have a MMDVM STM32 with a Kenwood D700 it’s receiving but no audio coming from handheld anytone 878uviii plus I can see the signal strength full scale on both radios just no audio Robby/AA5AF

Hello Group, I am still looking for a repeater quality antenna, preferably a set of 4 exposed dipoles for a project in SW Fla. This is to replace a current antenna that is in service but needs to be replaced. I don’t mind driving to pickup the ‘right’ antenna of course. Should be something useable in the amateur VHF/2mtr spectrum of course. Thanks in advance for reading. – Mike, K4CVL

I have both of these duplexers available to replace an existing system. The site itself is a water tower with an existing DB224 that has been made available to me. It is mounted at the very top-center of the tank. There is a backup fire department repeater at the site on UHF. I don’t even think it’s plugged in. The tower also has 5G panels mounted all the way around the perimeter. Given that space is not a consideration and all things being equal, which of the subject duplexers would you choose to put behind an MSR-2000 running 50 – 60 watts out of the PA? I have experience with the WP-641, but not the Sinclair. 73, Mike WM4B

I’m looking for a schematic for a Motorola MSF 5000 UHF Repeater Amplifier 75w Model TLE2522A. if you have one, please let me know 73, …Gary, KE8O

Good evening all, I'm having difficulty reading two (very dirty) Icom FR-4000-3 repeaters that I recently acquired for rehab. My software is CS-F3000 version 1.1 and I am using a genuine OPC-478 cable with a homemade OPC-592 (mini-stereo to RJ-45) adapter. PC is Windows 10 with a known good usb-serial adapter. I've double checked the simple two-wire adapter pin out and am confident I have RJ-45 pins 2 and 7 properly terminated to the ring and sleeve of the mini-stereo. No communication between the radio and software. Is there anything special about putting the FR3/4000 series repeaters in "clone" or programming mode? No specific guidance in the owners and service manuals other than indicating power-on is all that's required (unless entering service mode, which has separate instructions). Any insights are greatly appreciated. Jeremy K1LFK

I’m looking for a 107.2 Hz Vibrasender for an MSR2000. It looks like either the KLN6210 or KLN6824 should work. 73, Mike WM4B

Hello Group, I thought this task would be easy. But the more I delve into the programming the more confused I become. Here is my situation. *Radio* Astro Spectra-T04KLF9PW4AN (1 meg 2.5 kHz) I don't believe this to be a Spectra+ *Control Head* W4 Fully connected to transceiver Power cable also connected. All cables connected as when radio was in vehicle. *Computer* Win 7, 32 bit laptop with one USB 1 port and 9 pin serial port. *Motorola RIB* I have a real Motorola RIB. DO I REQUIRE IT? *Programming Cable* DO I REQUIRE A RIBLESS CABLE? What cable # and where do I connect radio end? With control head cable connected to radio I have one 25 pin female connector between the handle on the radio. Is the programming cable connected to that or does it connect to control head? *Programming Software* My information tells me that I require CPS 5.02.xx or 5.03.00 . I see the CPS is readily available but if some good hearted soul could mail me the CPS (if it's legal) I'd be happy to reimburse time and postage. I'm tearing my hair out and I only plan on programming six or seven VHF NB repeater fxs. and a few "Talkaround" channels. Appreciate any and all help. Tim Hardy AE7TH Vashon Is. Wa.

Hi. Have anyone make-cp.exe for R100 ?.

I am using a Kenwood D700 radio with MMDVM STM32 hotspot I tried using it as a repeater for the local area for emergency and regular use I putting the radio in packet mode 9600 baud open modes of: DMR - TG Brandmeister D-STAR - TG XLR295A FUSION - TG US KCWide NXDN -TG 711 the problem is it got stuck on KCWide and would not go to DMR or any other mode it help will be appreciated Robby/AA5AF

At least on the TKX90 mobile radios, removal of chip cap C10 (0.068MF) adds more highs to give more crispness, less muffled voice audio. This is located on the mike PC board with it's location marked. John

I bought a 510 at a hamfest...decent price ... for my repeater. Anyway, I cleaned it up and put it back together.... 181Mhz resonance. Tried changing some of the vertical elements... still no good! I got a diagram for a 510HM and it's not even close. Anyone have any info???? This thing has 3 main elements, with one of them coming apart to make it 4. NH6FU

Hi all, This is a type of tube (electronic valve) that some of the old-timers may remember. This is a first for me. Some of the old receivers out of the 1930's-ish used them (about a century ago). https://en.wikipedia.org/wiki/Pentagrid_converter - Regards, Karl Shoemaker To contact me, please visit SRG's web site at http://www.srgclub.org for the current email address.

Anyone in the Monmouth County, New Jersey area that can program set of UHF CDM1250 (AAM25RKD9AA2AN) and VHF CDM1250 (AAM25KKD9AA2AN) radios for amateur service? VY 73 Martin Flynn W2RWJ

I am the keeper of GB3VS a UHF repeater in the UK .it operates using the ARCOM 210 controller ..which has 2 spare channels I am considering connecting it into the Allstar network but the site has no internet. We are a small group with limited resources so a a mobile SIM is not really an option. My home QTH is approx 500M from the repeater site. I am therefore looking at how I might extend a data link from my home to the site ? Alternatively link the repeater raw audio ( without callsign, time announcements etc) to my home QTH where it could routed into my hotspot Raspberry Pi. I am sure that someone must have attempted this at some stage?

Hello Group, Hoping to clear up my confusion. From my research I see that CPS 5.03 is best although 5.02 can be used. I do have Astro Spectra CPS 11.00.01. I can't find any information on this CPS. Is it usable. (really high ver.!) My goal is to program several narrow band channels. Modulation will be analog. 146.6875 (out), 146.0875 (in) Repeater will be NB analog with PL squelch and rpt. ID. No digital, just simple. I plan to use a win 7 32 bit laptop. I do have a Motorola RIB (if required) but not sure about the cable to radio. Any help will be appreciated. Thanks in advance. Regards, Tim Hardy AE7TH

I have a TKR-850-1 that was working fine but now powers up with an E2 error code channel data not written. Can read radio and all data is read and good. Tried rewriting data with negative results. Would like to try reloading firmware Does any one have a copy of the most updated firmware? Curren check sum C1C1

Hello, I have recently got a Helper Instruments PS 250. Does anyone have a manual or schematic for the Helper Instruments PS 250. thanks 73's Brian w7fdd
