Re: TRA 921 Speaker Pic
Are those Speaker/Mic connectors available? Can anyone tell me where if so and what they are?

The one that shuts down your power supply like has a shorted capacitor or a dead transistor. Tom Bryan N3AJA On 6/27/2020 11:07 AM, KB0SFP via groups.io wrote:

Re: TRA 921 Speaker Pic
Now I need to identify the pinout on the Speaker/Mic connector and I can make some progress...Also measure the output power/Frequency and modulation...

Bruno and others,

Thank You for the help. I uploaded a picture of the unit with some accessories. One speaker works with the unit although audio output is very low. The other speaker/Microphone?? causes my current controlled Power Supply to fault. I will upload more pictures and perhaps someone can say what that device is intended for. It looks like perhaps a speaker and Microphone combination. The radio does seem to work somewhat as I can hear noise in the speaker that changes with the antenna connected and when placed in the tune mode I can hear a tone in another receiver.

Re: New Syncal Owner
The 906 & the 921 were similar radios, and may have used the same accessories & battery box. But the Squadcal was xtal control, the Syncal is synthesized.

Re: New Syncal Owner
I think it's a TRA-921. It runs off 18v, Some battery boxes used 3x 6v lantern batteries. There is a manual in our files.
