Greetings,
I have a few of these Astro radios I am trying to simply program as LATA-1 through to LATA-4 just for talking between themselves at a remote site. By remote... I mean where the Cell Phones don't work... which here in the Yukon is a pretty good chunk of the Territory, I have been working this a few ways, but after much banging of my head has now lead me to here. I can receive when I turn on the radio, but nothing seems to work to actually have a conversation so I can program.
So far:
Computer pieces:
Running a ROG Strix laptop... Windows 11
- Running a Windows XP Virtual machine with serial pass through
StarTech 4 port serial to USB (has been quite handy talking to a mitful of Telco equipment such as a DMS 100)
Serial cable is a standard Cisco blue (DB9 to RJ45) with the RJ45 end cut off to provide wires to connect to a DB15 breakout
Basic radio:
Astro Spectra Model: D04JHF9PW4AN / Serial 494CDA1689 / Canada Type: KKHA 1091941441
When I turn on the radio, I am getting something from it on the Moto Tools app:

10:48:48 Port COM3 is open

... and it goes on to the point of scrolling. So I am seeming to receive from it... which to me would mean I am able to communicate with it. I can see the lights on my StarTech light up confirming RCV or BUS+ as outlined here: Making Your Own Spectra Programming Cable. My Cisco cable is confirmed here: https://www.cisco.com/c/en/us/td/docs/security/asa/hw/maintenance/5585guide/5585Xhw/pinouts.pdf (Appendix 5-5). I have the following as my breakout connect for this:
Radio DB15 Serial DB9
14 - Bus+ to 3 - RxD
10 - Bus- to 2 - TxD
9 - Busy to 8 - RTS
8 - Digital Ground to 5 - GND
However... when I try to use the Astro 25 tuner or the Advanced Key Administrator (APX CPS suite Release 36.00.01)... or through the Windows XP VM (Virtual Machine) the Radio Service Software (RSS version 9.03.00), all I see is tx on the serial and no rx from the radio. I have tried swapping the wires for pins 2 and 3 and then get nothing. So I know I have it right. Is there something else I need to do to open the radio to program? Is there another wire needed for a RIB-Less connection? Or maybe an internal jumper to flip to allow programming? Does anyone have a simpler way to get these to be fancy walkie-talkies?
Your collective wisdom is appreciated. I am going to give my forehead a break.
