The plate iron seems like 1/2 amp CCS judging by the weight.

Also, there might be a way to deliver them to Dayton. I normally go there, but can't this year, but my 4 buddies that have gone every year forever, I can finagle into taking them up there. They set up to sell vintage gear and odds and ends, so you would be able to find them at their tent farm.

Also linear amp interface box, hand mic, mic adapter, programing software/hardware, and manuals For Sale : . . Yaesu FT-757 GX, HF Transceiver: The Yaesu FT-757GX is an HF transceiver covering 160 to 10 meters with ten memories. The general coverage receiver tunes from 500 kHz to 30 MHz. Power is 100 watts CW, SSB, FM and 25 watts AM. The FT-757GX features IF Shift, Electronic Keyer, Squelch and Noise Blanker. The top panel has CW adjustments. The rear panel has numerous input and output jacks. It requires 13.8 VDC at 19 Amps. Features: 160-10 meters IF Shift Keyer w/Semi/Full Break-in CW Dual VFOs Noise Blanker 100 Watts Output General coverage receive Speech Compressor It should be noted that this is not the high quality rigs I normally sell, but an average transceiver, but the price reflects this fact. It does have dual VFOs, WARC Bands, and memories, as well as an internal keyer. Hand mic, power cord, and paper work included for $250. . . Yaesu XF-8.2M-601 Crystal Filter: The XF-8.2M-601 is used in the 8.2 MHz IF of many Yaesu transceivers, including the FT-102, FT-747, FT-757, FT-767, and possibly the FT-1000 series. I was told it would work in the FT-1000 but have not been able to confirm that, so please check your manual. The 600 hz bandwidth is ideal for CW, but it is also great for RTTY and other digital modes, including FT-8, PSK-31, etc. This one works fine. It looks fine also, as if that matters for an internal filter. It is a "solder in" filter. Only $70. . . Cable for computer control for Yaesu: This cable was used on a Yaesu FT-757 GX, but I am fairly certain that it can be used on other Yaesu radios as well. The radio end has a small 3 pin, in line, connector, which is of the same type as used to plug into the various PC boards inside the radio. The other end is a standard USB connector, which has a USB to serial converter in the USB plug. To put it another way, plug the 3 pin end into your radio, and the other end into a USB connector on your computer, and you should be good. This one works fine. Only $20. . . Buy all three of the above items (rig, CW filter, and computer cable) for $325. . . Yaesu FRB-757 Linear Amp T/R Relay Switch Box: Many of the modern rigs are not capable of switching the higher currents and voltages of the transmit receive relays of some linear amplifiers. This small box was made by Yaesu to remedy that situation. Although it was made for the FT-757, it can be used with almost any rig that needs a heavier relay to switch the linear amp. It does not even need to be a Yaesu rig. This box needs 13 V DC (and has an RCA phono plug for that purpose), and is connected to the rigs linear amplifier relay output with another RCA phono plug. The output of the box has both normally open and normally closed contacts, both terminated in RCA phono jacks. Contacts are rated at 600 VA AC, 150 W DC load, and will switch up to 250 volts and up to 5 amps. - This one works fine and looks fine. Only $40. . . Yaesu MH-1 B8, Hand Microphone: The MH-1 is the standard hand mic used on most modern Yaesu radios. It has a round 8 pin connector on it. The mic itself has up, down, and FST buttons on the top, to permit one to change the frequency. On the back is a tone switch to permit one to slightly alter the frequency response of the mic. If your Yaesu transceiver uses a round 8 pin connector, this mic should work for you. This one works fine, and looks fine as well. Only $35. . . Microphone adapter: This adapter will adapt any mic wired with the Kenwood 4 pin connector, and convert it to a Yaesu round 8 pin connector. Works fine; looks fine. $20 . . RT Systems ADMS-1802 Software/hardware: The ADMS-1802 consists of a hardware cable, plus a software CD, plus instructions to program a Yaesu FT-1802. These days the rigs have so many memories plus other features, that it is almost impossible to program them manually. The ADMS-1802 takes care of this problem for the Yaesu FT-1802. This unit appears that it might be new. Everything is included -- Software CD, Cable, and instructions. Also included is the serial number to make the software work. This retails for $48.95. Buy this one for only $30. . . Original Yaesu Manuals: These are the manuals only. All are originals, and not copies. Most are in close to new condition. FNB-9,10,11,12 Battery packs, $2 FT-720 R, 2 meter mobile, $8 FT-890, HF Transceiver, $15 FT-1802 M, 2 meter mobile, $12 FTH-2005 HT, $5 FTS-8 tone squelch unit, $3 FTS-12 tone squelch unit, $3 MH-1B A2B speaker microphone, $2 SP-101 P, Speaker / Phone patch, $5 VX-1 dual band HT, $10 YC-601 digital readout, $10 These are original Yaesu operating manuals only, in very nice condition. . . I also have many other accessories available such as many different types of microphones, HTs, VHF and UHF rigs, HF and VHF/UHF antennas, connectors, miscellaneous accessories, etc. Just too many to list here. Please e-mail your requests. . Prices do not include shipping from Florida. . Thanks. 73, Ken, W8EK Ken Simpson E-mail to W8EK at FLHam.net or W8EK at arrl.net Voice Phone (352) 732-8400 .

This RX was rescued as it was getting put into the trunk of a car by a man who's dad built it in the '50's and just listened on it, never getting a ticket. The dad passed on and the son didn't want it. I did go through it way back then, finding bad filters and coupling caps, cleaning up solder joints and doing a complete alignment, and the only failure I have had since then is the 6BJ7 detector tube, one filament went out of the 3 in the envelope. Of course it was the detector section, not the AVC or ANL where I might have skipped it for a while before removing it from the bottom of the pile of gear on top of it and removing all the screws. With that said, I found an issue with 80 meters that I neglected way back when, but became evident that something was wrong on 80 compared to the other bands. I did find the addendum for the prebuilt front end, but it doesn't show a complete schematic either, just a reprint of the RX1 manuals version. I found an 82pf across the 80 meter antenna coil, which made the coil tuning mushy and the ant. trimmer not very effective. When I removed it, sensitivity went up greatly, and the ant trim did it's peaking job like it was supposed to. Does anybody know if there is supposed to be a cap across the 80 meter antenna coil, and also across the 40 right next to it? The 40 meter cap is a 100pf unit, with color dots, while the one on 80 is the more modern with writing and the coded 820 for 82 and no zeroes. If it is supposed to be there, is is an 82PF? The parts list for the front end does not show these caps listed, the cap list is rather short, at first thinking they listed only the parts drawn on the addendum, but they do list all the coils, even though most are not shown. Also, if anybody has any suggestion on why the converter band has poor sens and breaks into oscillation, that would help too. 15, 11, 10, no problem, with factory spec sens and no instability, but the convertor band is a mess. I was checking the tubes, and put one of the 6CS6's in the tester and turned it on, it got so bright at the bottom, thought I had left the filament in 12.6. I looked closer, and where the filament goes into the cathode, a bunch of the coated wire was in a big knot right at the bottom of the tube and lit up like a light bulb. It is a Raytheon 1958, and checked just fine too. Charlie, W4MEC in NC
