I am using a straight through DB25 cable from a computer supplier with no problem. I'm only using a 2 foot cable so I cannot tell you that a longer cable will work, but I'd bet on it. The speaker audio doesn't go through the same cable on the A3. The newer A3 uses a round cable that you might have ...

Thanks. With apologies for the simplicity of this question...is changing out the front panel a plug in process or would some mods be needed? I'm trying to decide between repairs to an existing A3 model vs a god deal on an A7 and moving the front panel of the current A3. Thanks again.

Does anyone have any experience converting a Spectra A7 to A3? Is any conversion necessary or might one be able to use the A3 control head on the A7 radio with the limited features of the HHCH(A3)?

Can anyone tell me how to use the controls on the Spectra Hand Held Control Head (HHCH) to change the scan list, change priority, etc.? Pressing and holding the scan switch shows "SE" on the display. Can anyone explain this operation? Perhaps share a scan of the key instructions?
Thanks,
Mark
