The Radio Information Board

You should be able to get a manual from: http://www.kenwoodparts.com/ Here is a link to some basic programming instructions: http://www.mods.dk/view.php?ArticleId=1879 Is this a "H" or "GH" model? The "H" is 32 channel and the instructions in the link above should apply...

You need to locate and connect both pins of J401. Do not ground it.

The bandsplit is 150-162 with retuning. The b/w is 3 MHz for RX and 5 MHz for TX so you need to retune it within the bandsplit for your particular frequencies.

One simple, inexpensive and "off the shelf" solution would be to get a garage door opener receiver and transmitter. The receiver will give you a contact closure when the transmitter is activated. This may be able to directly operate a very small, low voltage DC motor or it can be used to d...

I was searching the net trying to find an answer to something I have been curious about and found this very nice site you guys have here and thought I would register to ask this and probably many more questions in the future.What is the difference between wideband and narrowband transceivers? Just ...

If the radio negative lead is connected to the battery negative terminal it should be fused. If the vehicle battery ground cable goes bad, high starter or alternator current could flow through the radio if there is no fuse protection. If the radio is connected to chassis ground, this is not a risk. ...

The VHF/UHF duplexer output supports one VHF and one UHF radio. You could use it if one radio was dedicated to VHF and the other to UHF only, otherwise it will not work. Same band cavity duplexers are frequency selective to 2 specific, widely separated frequencies in the same band. The easiest solut...

I have always had excellent results from International Crystal Manufacturing. They are a little more expensive than some others but they get it right the first time and the reliability is excellent.

Here is a link to their web page for GE:

If your antenna height is 35' and the terrain is smooth, the theoretical distance to the "radio horizon" (distance your antenna can "see") is 8.4 miles. Actual coverage is usually somewhat greater than this but I would say 10-12 miles with some noisy reception beyond about 8 mile...

The general Phoenix specs say "136-174" but the actual Phoenix SX radios are either of 2 bandsplits: N5HH 150-174 N5GG 136-153 The N5HH1W40TB is 150-174, 40 W, 16 Channel (2 modes, 8 ch each), Non-scanning. I have used a "HH" Phoenix for local repeaters on the high end of 2M (146...

I checked the info filed with the FCC for Type Acceptance of the ARURPV516A.

It looks like it is made in China for RELM by "Shenzhen HYT Science & Technology Co.". Their name is on the manual that was filed with the FCC.

It is probably just a "Chinese copy" of a Kenwood.

Lets get the disclaimer out of the way first. I am not a radio tech. That being said, is it possible to change an MPA with a split of 136-150 MHz to 136-160 MHz? Any help with this question would be great. Thanks F I am not very familiar with the MPA but I just took a quick look at the service manu...

I have the manual for the MLSL260 that should be similar. I can email you a PDF copy of LBI-31795 alignment procedure pages if you want to send me a private message with your email address. It should work fine on 6M with a little tweaking of the VCO. The 260 RX VCO tuning procedure is to monitor TP2...

The Maxon software works fine with the GE Monogram radios. The GE “TQâ€￾ and the Maxon cables are not the same.

The GE TQ cables are for a parallel port and work only with the GE TQ software. I don’t know if there are any issues with use of GE software with a Maxon radio.

The Maxon SPC-4000C cables are RS232 serial and work only with the Maxon SMP-4004C software.

Here are some tips on how to use the Maxon software and cable:

The SMP-4004C runs with no problems under DOS. To run it under Windows you must put the “/Iâ€￾ switch in the command line or the PIF file. This is a Windows 3.1 program and there may be problems with later versions of Windows. It avoids a lot of problems to just run it from a DOS boot.

You need to remove the radio’s Auxiliary Relay and connect the red wire of the SPC-4000 to Pin 1 of the Auxiliary Connector as well as connecting the 6-pin plug to the Program Connector.

For a VHF radio you must determine if the EEPROM is a 93C46 or 93C56.
If it is a 93C46, select “SM-4150â€￾ on the radio menu. If it is a 93C56, select “SM-4150EXâ€￾.
GE VHF Monograms are 93C56/SM-4150EX. This is the most common problem when someone says they cannot program a GE radio.

The radio must be manually put in “PROGâ€￾ mode.

Follow the on screen instruction provided by the SMP-4004C software and everything should be fine with either a Maxon or GE Radio.

Don’t forget to reinstall the Auxiliary Relay when done or you will wonder why you have no receiver audio.

Maxon software and cables are available from TCS Wireless:

Sorry, but I don’t have a schematic for the cable. There is no schematic anywhere in the Maxon manuals.
