The good news is that they designed this one to top the FT-101 radio. The design is more sophisticated, the receiver is MUCH improved both in sensitivity, rejection, selectivity and best of all, the NOISE BLANKER is harder to bleed. They had to use three of the smaller 6146 tube to get about the same power as two of the 'sweep' tubes used in older Yaesu transceivers. It's a bona-fide industrial tube that will get rare and expensive someday. Compared to sweep tubes that are ALREADY rare and expensive, that's a good thing.



The bad news is that they used a fatally flawed family of small printed-circuit relays with pins in a pattern like a Dual Inline Package chip, hence the nickname "DIP Relays". The relays are used for transmit/receive switching, mode switching and to cut the preamp (yeah) in and out. When they go bad, all sorts of stuff starts cutting in and out. Simply keying and unkeying the thing, listening to how fast the receiver comes back, or watching the wattmeter (scope is better) for any hesitation when you key up may reveal flaky relays. Pushing the "Preamp" switch in and out, seeing that the noise level goes up and down when it should may reveal a flaky relay there. Somewhere here I have the URL for a ham in Spain that gathered the cross-reference data to replace these weird little parts, and published it on a web page. Yaesu is permanently OUT of some of them, and substitution is the only way to replace those. If you're interested, I can dig that out and post it here. I'm trying to cross-reference the numbers he used. The brand he chose (Omron) seems to use different stock numbers here from the ones they sell in Spain. Go figure......
