Have a look at the 1969 vintage Sony “88” bookshelf amp/tuner/decoder set at my office. I stream music from my Mac to this little amp whenever I’m at work for some years now. I have two small Magnat speakers and a Yamaha subwoofer connected and vistors are always amazed about the great sound quality of this set. But this morning, no music but only a loud hum from the speakers after power on. After half a century the two 2200μf / 25V caps in the power supply of the TA-88 had enough of it all. Two new capacitors from the local electronics store for a mere 3 euros in total, half an hour’s work, and it plays like new again. Love vintage audio gear!
What a great day to work on 10! About 40 stations responded to my CQ calls on 10 meters this afternoon. Worked lots of American stations, also stations from Canada, Russia, Ukraine, Turkey, Brazil, Cuba, Poland, Italy, Slovakia, Hungary, Romania, France and Japan. I worked all of them on my HyGain P-500 vertical bought as “new old stock” for 50 euros at a Ham fair in April. Production date august 1980, new in box. This antenna was legendary for DX work on the 11meters CB band in the 1970’s. I converted it for 10 meters and it is a really good DX gun! I was not the only one interested in this antenna as you can see in this video from M0OGY 😉
Off the air for a few days due to failure of the front mic input of my TS-870. I recently bought a used MC-80 and it seems that bad solderwork in the mic plug has shorted/fried the mic input. Input from the rear ACC connector (digi modes) works ok, so I suspect the AD822 op-amp in the front mic circuit is the culprit. Note to self; always inspect the cable and plug of a second hand mic.
UPDATE: Fixed the transceiver! Picture gallery of the operation here
