Re: Possible to operate a gr1225 without control head?

Hi Guys:

Lets set a few things straight here.

With the control head missing you will not be able to channel steer the radio from the rear connector. You can use the GM300 volume board to program and even run an R1225 but the DISPLAY BOARDS are different.

Re: Astro Spectra - bad caps - every production run?

Astro Spectra Plus by firmware/software is pretty much an XTL. However hardware wise (minus vocon board) are the same as a regular astro spectra. With that being said the only thing different between astro spectra and analog spectra is the command board/vocon. I realize I'm a few years behind on th...

Re: XTL5000 Dual Radio

Re: GR1225 Repeater not re-transmitting. . . .

I'm not sure from reading these posts if you actually ever read THE RADIO with the RSS. If the RADIO has a control head you read and write to the radio through the mike jack it.

Re: Syntor X9000 low band programming for 6 meters help need

FAT Syntor the easy way. First of all, get the firmware that you want to use. Stock, 128M or Dual Radio. I'm not going to go into PROM part numbers right now, just the methodology. If you want to go above 32 modes you will need to change the codeplug PROM to a 2864 EEPROM. Be sure to move the push p...

This problem exists with Astro Spectra, Astro Spectra+ and XTL5000 mobiles.

Re: Maxtrac HLN5569A version 5.34 Eprom Cancelled ?

There was also a 5.34B version, same part number. You can make your own proms with a commercially available prom reader/burner for your computer.

Also if my memory serves me correctly that one is a 128K Prom. You can get them at Mouser and burn your own.

Re: How to program Radius R1225?

You can use the volume/microphone board from an M120 or a GM300 to turn the radio on and program it. You will need a jumper between pins 7 and 8 on the front connector to turn the radio on IF you don't have the proper control head (front panel) for it. You can PROGRAM the radio to operate as a stand...

The problem might be a defective DRAM (Dallas something or other...it's like an IC but it's a block and it's about ¼ inch thick).

Just replace the firmware with a Maxtrac v4.0 P/N HLN9277A, blank it again and then try to program the radio.

I have done this in the past and it cured the beep.
