High Power Astro Spectra Cable - W3 head
Posted: Tue Feb 27, 2018 8:54 am
Hi everyone,
New here, please excuse the question if it's already been answered.
I have a VHF high power astro spectra, model T04KLH9PW3AN designed for the W3 head. I'm attempting to make my own cable, since the "Y" cable seems to be unobtanium, either from cost or availability. I wired a male DB25 to bring out ignition sense (pin 3) and speaker audio (24/25). The rest of the pin go straight through to the female end, pin-for-pin as they are on the W3. The W3 does not have many pins, so I only connected the ones that are required. ie, pins 24 and 25 exist on the head, but I didn't connect them to the deck since I figured they are only needed for the speaker.
The problem is, I get the fail code, "FAIL 01/90"; general hardware failure. A few idiot checks:
- I've cycled the power. No change.
- The RIB is not plugged in when I power it up.
- Using the leftmost DB25 (near power connector)
- DC input is 12V
- ignition sense seems to be correct; radio powers off when I disconnect the pin.
- I have not attempted to read/write from the radio. Internet auction claimed it was functional, and a friend who purchased the same model from that auction has successfully read/written to their radios.
Thoughts? I either have the wrong pinout, or it's DOA.
Thank you!
