Astro Saber 3, 450-512 Range Radio for Amateur use

Post by ckillian »

All,

I may have screwed up. I recently purchased an Astro Saber, H04SDF9PW7AN, 450-512 mHz handheld.

Using CPS 5.03.0 I set it on a a local repeater. Seems to be deaf.

Question is; is this radio actually suitable for use in the 70 CM amateur band... or can it be made to work?

Thanks all.
Chuck...

It should handle 440mhz with no problem. Sounds like your radio has an issue. needs to start with a tuning with a service monitor to put into alignment.

I do not believe there are any soft pot tuning values for 440 on a 450-512 radio. Are there? GARY

That's correct - there aren't. However, speaking from VAST experience with the ASTRO Saber UHF-2 operating in the amateur band, I can say that I have *never* experienced a problem doing it.

I agree the OP must have a hardware issue with the radio, or the OOB mod was done incorrectly and has affected some part of the radio's tuning values elsewhere.

Do some testing with the radio in it's rated bandsplit, I bet you'll find you have issues there as well. Once again, I've never come across a unit that wouldn't work in 440.

Then again, in my locale, repeaters are TX high RX low, so the radios are listening from 445-450 and transmitting from 440-445. I cannot speak for the inverse, but I have never heard of any issues.

There are not, but the RX front end filter alignment can affect OOB receive performance. Been there, done that.

OP, you need to put it on a service monitor and see what it's doing. RX sensitivity should be in the .19-.21 microvolt range throughout the operating range of the radio.
