Re: The bottom line on Ham radio
An Icom 706 (any series) might actually make a good compact receiver. Especially because they often died when the transmitter final transistors blew, and for some years now there have been no replacements available for those. So there should be units being sold "as is, for parts, does not transmit" out there.
But equally, be warned that a 706 series would be a poor choice for anyone expecting to transmit in the future, as any damage to the finals is not repairable. In theory, sure, that would never happen. In practice, there was a lot of protest about this.
At the right price...as long as you know the story. They also drain power even when they are off, and they are vulnerable to voltage damage, as the input power uses capacitors rated at 15VDC. On a 14.4 power supply, those should have been rated 25VDC. Capacitors generally are only manufactured to a 10% voltage tolerance, so a 15 volt rated part is really only designed to be used up to 13.5 volts, which is less than normal alternator power.
Good radios--but like many, some frailties. There are reasons Icom discontinued them.
