Are those Speaker/Mic connectors available? Can anyone tell me where if so and what they are? Not a connector/Plug I have although I do have quite a few... KL7AM

Correct, it is desiccant.? There is one in the radio just like it. The one that shuts down your power supply like has a shorted capacitor or a dead transistor. Tom Bryan N3AJA

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... KL7AM

The thing you see that looks like a pilot light is?Desiccant. Dennis Starks Military-Radio-Guy KB?SFP HFpack/Milpack/MMRCG Monitor all: 3996usb, 5357usb, 7296usb, 14342.5usb, 18157.5usb, 29.4fm,

These speakers are powered. I/E that have an audio amp in them. This amp is apparently defective. Dennis Starks Military-Radio-Guy KB?SFP HFpack/Milpack/MMRCG Monitor all: 3996usb, 5357usb, 7296usb,

The speaker on the left causes a fault in my power supply. What is the device in the lower left with the white center? I see the transceiver has one too. A lamp? Thanks! KL7AM

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??

Same with Syncal 30! Robin G?GNE

Hello Marty, Looking at the picture, the radio you have is a TRA-921 (Syncal). You can find the technical manual here (in three parts : TRA921_tech_1of3, TRA921_tech_2of3, TRA921_tech_3of3) :

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. Dennis Starks Military-Radio-Guy KB?SFP

Marty Looks like the TRA 906 Squadcal, but cannot see the front face of radio, that would have been better ?? If it's what i think it is then 18volts Maybe wrong ? Stuart G0TBI

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. You very lucky to have the speakers! Dennis Starks Military-Radio-Guy KB?SFP

I attached A picture and also added one in the files section. I will take more and better pictures for the album this pic came from the ad on Facebook where I bought it. KL7AM

The one I have is a Syncal but I haven't found another like it. I also haven't found this model in the files section. Maybe I can post a picture in the files section KL7AM

Brought home an early Syncal with charger and looks like two speakers (I assume one is the microphone although they do look alike) This one only covers through 7 MHZ. Looking for a manual, what DC

Hi Guys, I just took apart the rear PA module to fix something and there are too many wires and no labels:) Does anyone have a picture or a diagram for the PA wiring to the Radio? I have the manual

There are about 50 variants of the Racal RA250 handset Pete G7DXV
