Astro Saber Bandwidth

[hotdjdave]

I have an Astro Saber III, Model: H04RDH9PW7AN, Flash Code: 0000040000006. It is suposedly 403-477 MHz. I have read somewhere that via software, the bandwidth can be adjusted (I want it to go up to 512 MHz (or at least 490 MHz)). Is this true? If so, how?

yes it can be done, BUT, it involves surgery and codeplug hacking i believe, better off trying to sell the one you have and buying one that is the bandsplit you are looking for... i think i saw a thread about doing this not too long ago

You have a 403-470Mhz radio.

It can go a couple of mhz outside of that range but not much further.

Better off to buy an s split radio.

No surgery required. Just a little editing to the RSS or CPS.

The detailed instructions are at batlabs, where they've been for years and years.

I originated the RSS bandsplit hack for the Astro Sabers.

Any Astro Saber should be able to squeeze an extra 10 MHz out of its band range, in either direction,
and still work pretty well.

I've opened up the RSS to allow a VHF radio to go down to 122 MHz (and receive AM air traffic "on the slope" with readable voice quality) and up to 187 MHz. Purely to see how far out it'd go and still work.

Keep in mind he's looking to go at least 20Mhz out of band.

I think he's going to need another radio.

I know an Astro Saber will receive at about 482mhz ... but I suspect it won't go out-of-band much further than that.

Depends on the VCO. I have had several non S split radios that worked 403-5xx and locked. When I would visit the left coast, I was able to listen to LAPD without a problem on the AS3 from Ventura County.

Pretty much, its a crap shoot. Some will, some won't. Just depends on how forgiving your actual VCO is.

No hardware changes are required...just a little software hack in the programming software. Visit Batlabs for more details.
