Spectra Astro, duel radio option?

Postby syntor9k » Wed Nov 15, 2017 9:16 pm

Is there a Spectra Astro, duel radio option (RX/TX for both)?

When using duel radio, is duel receive an option, or is the other radio just more channels to scan?

Is Wide or Std Dev FM possible (ham use)? I am interested in the Astro because of P25.

Can any head be used?

Are there gotchas?

I know about the Kenwood, I'm looking for used/ lower cost radios with wide (std) FM and P25...

Yes, it uses a special W3 HHCH and is well-discussed here. Feel free to search

Are we talking about true dual radio or HRR?

Yes, I often find my Astro units having a go at each other:

OK, dual is what I meant.

What I was asking about is W9 head and two trunk transceivers, one VHF and the other UHF.

As per escomm's response, it can only be done with W3 HHCH and special software and some cables. Basically it's a no.

On the Astro Spectra or the XTL5000? Only the XTLs could use the dual-radio W3 cable that I know of. For Astro Spectras your options are/were the HRR cable (no TX on secondary radio) and upgraded firmware in a SIU, which only worked with the old-ass A3 HHCH.

Bummer.
I want a P25 and FM transceiver, and have a small car. Not much room left over for two more radios. I wanted to look at what available used older radios that I can afford. XTL are right on that line. The only real option is the Kenwood NX-5700 with duel radio. But thats too expensive.

So the XTL500 can? What hardware is needed?

A Y-cable, a special cable for the HMN4044 W3 head, and two XTL5000 bricks with W3 TIBs. Oh, and codeplugs and the means to push them into the radios. Dual radio was not a field-orderable option. Search the forum, it's been discussed previously and pictures were posted.

With the XTL5000 it works both radios can transmit?
Should I restart this subject in the XTL-5000 forum?
For HAM use such as, wideband FM, and P25, are their other issues?
Is there any reasons that a XTL-2500 cant be used?
My long term goal is ether buying new NX-5700 duel radio with P25 (too expensive IMO) or, if the Motorola/ used is cheaper buy it (requires lots of shop time and software upgrading = unknown cost, trouble finding HAM friendly shop, friendly also in this context means, does not charge me much, beside actual cost).
Can you program RSSI out like you can on the Spectra and assign a button to it. Or is there better way to get signal meter?

Yes, both radios can TX and dual concurrent RX is supported. Won't work on a 2500, only the 5000 supported it. IIRC the only deployed configuration used 110W 380-470 and 136-174 bricks. No s-meter or RSSI function on conventional. :(

Is there list somewhere of what is actually needed to make the 5000 work in this duel band mode?
Software and hardware?
