Problem between ASTRO SABER and XTS3000
I am trying to set up two radios AS and XTS to communicate. I have ASTRO enabled on rx and tx on both radios as well as NAC 293 and digital CSQ. Talk group and signalling are disabled. I only get digital noise on either radio when recieving. I have checked everything that I can think of and compared the settings between the two radios. Any insight would be helpful. Both radios are R7.XXX and DSP 8.XXX. Thanks!!!

More important than the flash....what is the letter prior to the DSP on these radios......cgroftmc wrote:I am trying to set up two radios AS and XTS to communicate.

Digital Flash
A radio can be given a digital flash either legitimatey or by other means and not have the firmware capable of correctly recieving the digital signal. That is the problem you are having with that radio.cgroftmc wrote:The XTS is a N. The AS is an A.
"A" means analog only, but the AS is transmitting digital. I can hear the data stream on my scanner.
Hack Job???

Sounds like one of the radios is horibly out of alignment.
I bet they talk to each other in analog just fine
IMBE requires very close alignment for it to work. IMBE deviation is something like 2.83khz. If off by a few hundredths, can cause problems.
If you have a digital BCD396/996T, try adjusting the scanners "P-25 fine tune" up/down while talking IMBE. If you can hear at least some audio (even extremly choppy audio) while adjusting the fine tune on the scanner, thats a dead give-away that IMBE radio in question is out of alignment something fierce

Really! Thats very interesting to know - I had just assumed that the A firmware had all of the IMBE software removed for licensing reasons.
