My Harman Kardon HS 250
Possible that the microprocessor stage is not working and is not conveying any display to the unit.
remove the cover and check the 5Volt rail to the mP section. If the voltage is absent check on the 5 volt regulator.
If present and there is no life, then check for oscillatiion of the crystal, might need a CRO to confirm if the mP is working or the clocck signals are present, if data tranfer is present. If not mP is faulty.Take help to confirm and find a source, might be approach Harman Kardon.
How do I connect a goldwing cb antenna to a harman kardon cb module
The Goldwing CB antenna uses a standard RF coax connector plug.
Don't know what the Harman Kardon module uses - I tried researching some sites such as Harley Davidson forums, on which the HK CB is standard.
Nothing found re actual antenna socket.
However, some important points to note, which you may already be aware of, as a CB user:
The antenna and CB should be matched to each other for several reasons:
Mismatched impedance and resonance can result in signal power attenuation or loss.
If SWR is too high, say above 3dB, this could damage the CB.
An incorrect antenna may exceed the FCC regulated guidelines for bandwidth, cross-talk and radiated transmitter power.
