Does 403 - 470MHz bandsplit Spectra or Astro Mobile Exist ?

Post by Leadenwah »

I've seen plenty of handhelds with the 403 - 470 MHz bandsplit, but do not recall any Spectra or Astro Mobiles with that split.

I'm replacing a mobile which is on a company business repeater and the extra lower band width came up as a matter of interest and is certainly not required. No trunking, securenet or any exotics are needed, just conventional old UHF.

Thanks

Regular Spectras are in approx. 30Mhz bandsplits, so there's one split 403-433 and one 438-470, Astros look to be roughly the same, although I think the lower split is 403-437.

To cover the 403 to 470 split, you'll need to look at either the MCS2000 or the XTL series. No spectra, astro or otherwise is capable of it.

Astro bandsplits...

While we're on the subject, why doesn't some person who
has the correct information post the Astro bandsplits once
and for all? I'm talking about the UHF splits on the portables
and mobiles, which I believe are incorrectly stated on the
Batlabs data sheet.

Well, Astro Spectras, and Astro Sabers, while they share some similarities in the lettering of the band - don't always equate to the same thing.

There are 403-430 (Q) split, 438-482 (R) Split, and 470-520 (S) Split.

However, the RF boards for the Astro spectra's are configured for 4 ranges, which means that the R split should be split up in to 438-470, and a 450-482 split should be in there. Can someone clarify - I don't have my service manuals handy.

Now you look at the Portables, there's only two splits:

403-470 (R) and 450-512 (S).

Now - if you want to take in to account the XTS5000's...

There's 380-470 (Q) and 450-520 (S) which is even more confusing.

Your not the only one...

You can add the Professional series radios to that list.

If those are ham radio grade, then the competition must only be producing bubblepack radios nowadays :roll:

Thanks for the band split info folks.

I had guessed that might be the case with the Spectra splits. Thanks for clearing up the Astro mobile / portable split confusion.

The MCS 2000 seems to be the closest candidate. We're kind of used to the inexpensive used Spectra mobiles, but at least we're sure now.

Thanks a lot.

The comment about the professional series was a jab.. They're probably not suited for public safety grade, but for a lower tier radio, They're loaded with features for a reasonable price.
