• 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.

HT1250's Won't Power Up

Hey Guys, I dug out some HT1250's that we used back in the day. Most of them power up and work fine but three don't despite getting new onboard batteries as well battery packs. Any chance I can revive them or do I consider them a lost cause? Thanks!

There is a lot that can be wrong with it. Could be a bad volume pot, could be faulty contacts on the back, could be something wrong with the board itself, etc. But if you have tried to put new batteries on it and it doesn't power up, I'd say that's good enough reason to assume that there is something wrong with them. Repairing them might be an option but it all depends on how familiar you are with radios and how good you are with soldering.

Agreed. Only other thing I could think of would be a bad EEPROM. Once those go, it’s all down hill from there.

Yeah, I had a feeling that was going to be the case. I could invest the time to get these puppies up and running but I might have to opt to look into some replacements. Thanks for the input. Happy Holidays!!!

Just out of curiosity, what are you planning on doing with the broken units?

There's also the circuit board fuse that can fail and cause the same problem. Here's a snippet from the detailed service manual:On Board Fuse Location.png

@KG4INW beat me to it. The service manuals are available on the internets at various locations, but F501 is where I'd start. Not knowing the band of the units you have in your hands, here is what I have saved on my computer for MTX/HT/Pro units.

complete disassembly of radio down to circuit board and using a fine tip soldering iron.

I planned on donating all of them to a local charity that I work with on a regular basis. I will at least try to replace the fuses with the info you guys provided here so I can give them a few more working ones rather than giving them ones that are DOA and have them pay to get them repaired.

Where do you guys recommend that I buy the replacement fuses? BTW, these are UHF 450-512 MHz models.

Thanks much.

Non-profit or not, they do need to be licensed. There is no FCC waiver for non-profits or donated radios. Be careful about giving anyone these radios. They likely will assume they are 'just expensive CB's" and not understand the licensing requirements.

The fuse is a chip fuse. You'd need to find the exact size/rating, but you can probably find them on Amazon.

Totally understand. They would need to pony up that themselves but it would still be cheaper than buying the units, too. I can't remember but I think the GMRS fee is about $50?

Before you go and buy the fuses, you can very rapidly check the continuity of them to see if the are, in fact, open.

Pretty straightforward disassemble and I've located the fuse. KG4INW, thanks for the link to the new one! Going to order and will replace it. I'll let you guys know if it worked.

Test the fuse first! Don't spend money if you don't have to

GMRS license only covers individuals and their immediate family. A non-profit/business/etc, wouldn't be granted a GMRS license. Each user would need to pay $80 every 10 years.

On the other hand, an itinerant/non-coordinated UHF business license would cost a few hundred bucks at the most. But that's well outside the capabilities of most non-radio guys to do.

If you had a schematic or PCB layout, I'd recommend you trace the power (+V) starting at the battery and see where is vanishes; that's where the problem is. (And if that still doesn't present a solution, do the same thing with the ground trace.)
