I recently picked up an analog VHF Spectra for use strictly as a receiver. Once I hooked everything up and programmed the radio I noticed there is a low, but noticeable hum in the background whenever the radio is receiving (reminds me of listening to an old AM radio).. Is this, or could this be, a symptom of bad caps that these radios are notorious for? Which brings me to my next question.. I was doing some reading and one post mentioned the radio would need a realignment after being recapped. Is this really the case? I have no problem recapping the radio myself, but I certainly don't have the tools to perform a realignment.
Thanks!
Thanks!
