M1225 model decode help needed

[artman]

Hello, I just bought this radio at a pawn shop for $5.00 and I need some help with identifying the model. The model # is M44DGC90E2AA. Under the cover are these two stickers with these numbers HLE9087APH and HUE3579A. The radio has a 16 pin connector on the back and 4 channels on the front with a&b buttons. I would also like to know if it can be programmed for the ham bands. Thank you for your help and advice, artman ke5wxn

All I can tell you for sure is that its a 40 watt, UHF, four channel. I'm not sure about the capability of the UHF to go to Ham frequencies. If you're using an older version of software (up to 3.1), you should be able to hold down the shift key on the computer's keyboard while entering the frequency with the number keys along the top of the keyboard, not the numeric keypad on the side of the keyboard. In other words, to enter "444.500", you would see "$$$.%))" (without the quotes) in the window in the RSS (remember to release the shift key to enter the period!). I'm not sure if this works with the UHF versions or not, but I know it works with the VHF.

Thank you for the info kf4sqb. I guess that I am wondering if this radio is capable of more channels and what the current band split is? Tomorrow I will pull the board out and see what model #'s are under there until I can get a programming cable built. Thanks again for your help,ke5wxn.

Yeah, the UHF 1225s work great for 440 ham. The lowest I have ever taken one is 443 MHz.

As for channel expansion, even if there were a published hack it would require a new display board and those (if they're even still available) cost almost as much as a new radio does. Possible? Yes. Feasible? No.

Any cable that works for the Maxtrac, will work on the M1225, but beware that the radio will go into transmit as soon as you slide the connector into the Mic. receptacle.

This is a known trouble spot for this radio, and others, but there is a work-around aside from powering off then on again, but I don't recall the exact procedure though.

...but beware that the radio will go into transmit as soon as you slide the connector into the Mic. receptacle.

I've personally never run into that problem (not saying it doesn't exist, just that I've never run into it). Perhaps because I always power the radio off before plugging in or unplugging the cable. Interesting...

Thanks everyone for their help. I have successfully programmed the radio for my local ham repeaters! On a side note I was also successful at programming a p1225 for the same repeaters using rss 3.1 after the radio was programmed using rss 4.0! The only problem I am having with both of the radios is that I am getting reports that my audio is a little low. Any suggestions? Thanks again for all of your help, Matthew ke5wxn

Check the Wide Narrow setting, should be wide for ham bands. You may have to 'kick up' the transmitter Deviation a notch or two.
