Can an HT1550 with the split of 450 -515 be forced (?) to go down to the amateur band?
Thanks!
HT1550 highsplit to ham? Can it be done?

You'll need the FPP battery and CPS, but yes,it can be done.
Yes it can be done. You'll need the CPS (of course), and the programming battery.

First off, thanks to Rich KC9FNM my co-worker for figuring this out...I am just posting what he found and I confirmed works.
Recently we bought some HT1550XLS's for the techs to use....all of them 450-527.....grrrrr !
Rich informed me he was able to get his to do ham, and actually have halfway decent performance.
First off you need the "programming battery"
Program in your ham channels into the radio. Program in the alpha tag, and everything else BUT DO NOT CHANGE THE DEFAULT FREQ. Also be sure to check the box for field programming. Again, leave the default freq at 52x.xxx MHZ !!!
Go into the radio configuration screen to the "EDIT" tab. Here's the magic...... follow carefully.
Lower the upper band limit from 527 to like 470 MHZ
THEN you can lower the LOWER limit from 450 to 442 or whatever.
The trick is to lower the window . So you want to go a few mhz down, then lower the upper split down. be sure to lower the UPPER limit first
Once you get a acceptable window, the INVALAD red colored freq will dissapper in the EDIT window.
Now....write the codeplug to the radio.....keeping in mind you have the default freq in you ham channels......this is ok....dont panic
Now that your radio is written, go into the front panel edit mode and enter in your ham freq's and PL's by hand. It will now accept the ham freq's.
I know it sounds odd, but it has worked with two HT1550's so far on the 450-527 split.
I havent went far enough to play with the RSS as far as reading then re-writing and stuff. i dont know if you have to re do the mod. But y'all are welcome to try and let us know.
Your mileage will vary.....film at 11....no warranty..."as is where is" and the usual legal disclaimers apply.
.......This is not my information, I take no credit for it. Just a messenger passing along what I've found.
Good luck and Merry Christmas,
HT
