![]() ![]() But crystals are impossible to come by nowadays. There is an internal socket for each band. The FT-707 can be used Fixed Frequency by the use of Quartz Crystals. Yes, the FT-707 can be drifty, I'll leave it on 24/7. I'm pressing into Data Mode service, mostly FT8. So the FT-707 is back up and working great. Oh, and my speaker is defective, just like the previous reviewers. Finally, the distorted transmit audio was due to a fried, and shorted Tantalum in the PA BIAS C13 - JUST LIKE THE PREVIOUS REVIEWERS FT-707. The defective VOX was due to a broken wire at the VOX GAIN potentiometer. The replacement semiconductors function fine. As for the MOSFET, the original 3SK73 is a Flat Package (HSTM) device, which I didn't have on hand. I used a 2N4416 for the J-310 as I have a few of these left in my parts bin, and have had great success using them to replace obsolete JFETs in my Drake R-7 and TR-7. Both are similar Low Noise, High Dynamic Range, UHF Amplifiers. My Early Version used a Sony 2SK125 at Q07, not the listed J-310. These were Q07 and Q08 and are directly in the Transmit Audio/BM Chain. I replaced a J-310 FET and a 3SK73 Dual Gate MOSFET on the IF Board. The rest of the thruhole components were soldered by a Wave Solder Unit from the factory and not disturbed since. #Short menu for yaesu ft 60 r mod#This could've been a Factory Mod as the soldering was done by hand, but quite well. Unusual, several of the listed 1S1555 Silicon Diodes had been replaced with 1N270s - a Germanium Diode. #Short menu for yaesu ft 60 r manual#A 1N270 had been soldered in place of the 1S1555 listed in the Service Manual on the AF Board as D01. I replaced about 30 Electrolytic Capacitors on the AF Board. His repair is pretty ugly, with lifted traces sloppily jumpered. Hal had put it back to Amateur Radio use by replacing the 11 Meter Crystals with stock 10 Meter Crystals. Like David's, my Transceiver apparently was also modded by CBers. I'm very grateful to the Review prior to mine, from David Burger, VK2CZ. It's a very early model using quite a few different transistors from those listed in the available Service Manuals. In addition, the VOX Circuit was inoperable during voice operation. Initially the FT-707 seemed to operate, but after a short period of time using it I discovered that it suffered from terribly distorted audio on both SSB and AM transmit. Prices were pretty reasonable as they were listed as Non-Working, Parts Only. I purchased the FT-707 and a Drake 2B from this person through eBay. A non-radio person had purchased a pallet of radios from the Estate. The FT-707 was in Hal's inventory at Land, Air Communications. Towards the end of Hal's life, the repairs became sketchy. For many years he performed sterling work. Hal is well known, and has 259 Reviews in the Amateur Radio Equipment Repairs section of these reviews. Hal had put one of his "Land, Air Communications" stickers on the rear of the heatsink. Inspect the transceiver visually immediately upon opening the packing carton.I picked up a FT-707 from the Estate of Hal Guretzky, K6DPZ. ![]() Please take some extra time to make certain that the important safety and technical requirements detailed in this chapter are followed closely.
