Astro25 VHF out of band modification

[vsp5151]

I need to lower the VHF frequency range on my Astro 25 to allow me to program the lower 2M amateur frequencies. I read older posts on this forum and find this information:
akardam.net Motorola Tools & Documents - CPS Out of Band Modification HOW-TO

When I follow this link I do not see the CPS Out of Band Modification How-to that was listed in an older post. What am I doing wrong?

What Astro 25 radio in the VHF split do you have that doesn't go low enough? The K band split already covers 136 to 170 something. Any lower and you're into the aircraft band

What he said. Astro 25 VHF mobiles and portables natively cover the entire VHF spectra. Now if it's an Astro Spectra Plus, it's possible that a K split may complain about being OOB below 146MHz, but native Astro Spectra CPS just gives you an error and allows you to enter the lower VHF stuff anyway.

Sorry for the wrong information. It is for an Astro Spectra Plus. I can not program anything under 146.000 MHz into it. I need to add some of the 144 and 145 amateur frequencies. I have several Astro 25 radios and can program them. I know you modify the PatMob file but I am very uncomfortable using hex editor unless I have better directions. I am 76 and have difficulty doing certain things on a computer. Thanks again for your help.

If you’re still looking for help, I can try and see if I can hex edit the CPS or if there is an easier way if I have time tomorrow morning. I will let you know when I get to it.

Wa-a-a-a-y back, in the Time Before Time Itself, there was a well-worn trick for exceeding band edges that entailed simply holding down the Shift key as the heretofore offending data was entered. As I recall, though, there were a couple of caveats, such as:
Releasing the Shift key at the decimal point,
(Maybe?) Needing to use the separate Numeric keys for frets,
And (probably) this only working with Radius CPSs. (Did I mention I'm old?)

Dunno if this'll help, but my info is still a bargain at twice the price, i.e , 2 x $0 = ...

The old shift trick, doesn't work for ASTRO25 radios

That works for a lot of the older DOS RSS packages. But sadly not anything that runs on Windows.

Hex edit CPS and cross your fingers. Most will play down to 144 with the split that cuts off at 146, some get fussy and the VCO won't lock. Good luck!
