• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

I'm looking for a mobile on a power supply for a blind friend. I may go with a M1225. Can I get one listed with a bandspread of 150 to 174, to go down into 2 meters with the shift trick?

Thanks.

Yes, the shift trick will work on a M1225, clear down to 144.000. Whether it plays that far, your guess is as good as mine.

M1225 VHF has up to 45 watts output. So you should plan on at least a 20 amp 13 volt power supply.

They run good at 25 watts.

Thanks to all for the replies. I'm not sure what the current is on the power supply. It's an Astron that came with a UHF CDM.

I'm sure cost is a factor but it would probably be nice to have a newer unit that has voice announcements. I would imagine for someone like that an audible announcement of the channel name and scan on etc...would really help.

I've done this before a few years ago with a GM300 for another ham with very limited visibility.
I put the weather in one of the channels.
And he knew to go up 2 or down 1, etc. to get where he wanted to go.

As long as we're on the topic of m1225's, does the same apply for 70cm ?

Couple of notes -

There is a 40 W version and a 25 W version of VHF M1225. The M33 is a 25 W radio. The M43 is a 40 W radio. They are not the same, so pay attention when you're buying one.

Never tried 440.

Taking a high power mobile and running it at lower power, unless it's designed to do that (they might be, I've never tried), might create some problems as far as spurious emissions and power consumption. The amplifier might not be stable if it's not biased as designed.
