[Premium-Rx] Cubic R-3038-10 Information Needed

[FRANCIS CARCIA]

Mike,
The R3030 has a stereo headphone jack so you could start there. Also see if there is one or two audio output boards behind the front panel. Maybe your's is a dual. The 3030 did not have connections to drive a speaker but all you need to do is connect speaker leads to the output of the audio amplifier board. The headphone output has a series resistor so the speaker picks up the audio output amp ahead of the resistor. I don't know anything about the 3038 but since there is only one control interface I wonder if both receivers track the front panel controls? I would think if it was a diversity radio the detector modules would have different part numbers. Good luck Frank, WA1GFZ

Hello,

I have a Cubic R-3038-10 Dual HF receiver. It is a 19" rack mount set similar to the more common R-3030. Unlike the 3030 my R-3038 has only one front panel display.

This is a very nice receiver. It is very quiet and sensitive and works well. The problems I'm having are due to a lack of understanding and I'm hoping somebody here can help.

I can only use one receiver. The radio is fully populated with both sets of receiver boards under the hood and a second set of ports and jumpers on the back but I cannot find the method of toggling back and forth to each receiver. If a button sequence exists that I haven't tried yet I don't know what it might be. I have connected one antenna port to an antenna and the second port to a signal generator on the same frequency thinking this radio might be set to an automatic diversity mode but nothing.

Of lesser importance I'm looking for the right pins on the J-12 Audio MGC port on back to drive an external speaker. 

If anyone has, or knows of a manual for this receiver I would appreciate any leads at all. Thanks in advance for any help at all.

Best Regards,
Mike Monnier
