“New Neophyte Receiver.” The 624 Kits version. Built a long time ago by me. Built-up board only, no enclosure. Includes air-variable cap I used to use with it. I have not hooked up this board in many years, but it used to work fine (of course, you’ve heard THAT one before!). With instructions provided in 624 Kits kit. $12.

Ramsey Electronics Model HR-80 80-meter receiver, built, in matching Ramsey
case. Works fine. With original documentation. $22.

Electronic Rainbow OSC-2 Code Practice Oscillator kit. New, unbuilt,
unopened. $4

Kanga LCK Receiver and Transmitter boards. Another project started and never finished. It was being built by me for 80 meters. The superhet receiver board appears to be finished; the transmitter board is not finished. Transmitter board still needs torroidal output filter coils and two torroidal transformers to be wound (cores appear to be missing from the bag) plus two BC183 transistors and one VN46 transistor and a few other Rs and Cs (also missing). Includes original instructions. No enclosure. Not for the faint of heart, but if you can finish it up it’s said to yield a nice rig. Needless to say, since it’s untested and unfinished it’s as-is. $19.

624 Kits version of “A Simple and Accurate QRP Directional Wattmeter.” From February 1990 QST and other ARRL publications, I believe. The one using two ICs (CA3160 and LM358) and a 0-1 ma meter. This is a built-up 624 Kits board kit, built by me but never put in a cabinet and tested. The bag includes the built-up board kit (with ICs, socket mounted) plus a bag of other miscellaneous and mostly related parts rounded up and corralled by me in hopes of eventually finishing it: these include about a half dozen mini toggle switches of various configurations, a bag of mechanical parts (PC-mount female RCA connectors, male RCA connectors, 9V battery connector). Package also includes a new-in-unopened-package 0-1 ma meter and enclosure to finish it off. Plus of course a copy of the original QST article. Again, please do note that since I have never tested the board it is as-is. $15.

Vectronics factory-built “Tunable CW Audio Filter.” Model VEC 841W. New in unopened box with original shrink wrap still intact. I had purchased this one new for myself, but then received one for a gift from family…better use the gift! It’s a nice filter. $35.

MFJ “Deluxe Electronic Keyer II.” The very neat one using the Curtis 8044 chip, with the front-panel meter calibrated for readout of speed in words per minute. This is one of the two keyers that was in daily use here up till the move. Works perfectly, beautiful condition. Runs on 5-9vdc, with built-in holder for four C-cells. No documentation. $20.

“The G3RJV Six Pack” board. This is a PC board with etched/drilled boards for six projects: Plug & Play Transmitter, LED SWR, Volume Monitor, RF Probe, Quick Receiver, and Crystal Checker. The individual boards are designed and pre-cut to easily separate from one another for building the projects. On this one, the crystal checker board is missing. The others are here; the Plug & Play Transmitter Board has been removed from the main board and construction thereon has begun (by me) of the 80-meter version – I’ve wound and mounted all torroids, so the hard part is done; also mounted some (about half, I’d say) of the remaining parts. The transmitter will need a 2N3866 or equiv for the output, plus a few other various parts. Includes original instructions. Note that this is not the parts kit, just the boards, with the transmitter board partially built up as noted. $12.

CWF-2 Audio Filter Board, by MFJ it seems I recall. Uses two 747 ICs and nice polystyrene caps. Board only, no enclosure, no docs, so as is. $3

International Crystal modules. Three of them, as follows: one SAX-1 by itself, one OX-1 mounted on an aluminum box that’s been outfitted with a switch and crystal socket to serve as a crystal tester (I checked this, and it works fine with 80 and 40 meter crystals), and another OX1 that appears to be for a higher frequency than the one that’s serving as a crystal tester but that has a crack in the board material (traces unaffected, it appears). The two loose boards have not been tested. $5 for the batch.

Trac-One “Deluxe CMOS Keyer” unit. Acquired a long time ago at a hamfest just because it looked so interesting. This is a keyer, which a quick check shows does indeed generate dots and dashes (but I did NOT check it with a transmitter). This unit also includes a “de-QRMer” – a very narrow audio filter that is hooked to your receiver, then in turn keys an audio oscillator in the Trac-One to de-QRM received signals, if that makes sense. I quickly checked it out, and that feature does appear to work too, but since I have no documentation and no knowledge of this unit I have no idea if it’s working right or not. I did not build this unit myself; the assembly is okay but could use some “neatening up” in some areas. Front has five controls (with knobs) and small slide switch for on-off, plus “lock” indicator light for the de-QRMer. Back has four quarter inch phone jacks, two slide switches, and mini phone jack for power. Top cover is missing. This could probably be a lot of fun to play with. Of course, as-is. $12

Bourns 3400-S-201 200-ohm ten-turn wirewound pot. Blue case. Quarter-inch shaft. It was obviously pulled from something at some point but is exceptionally smooth and checks out fine. $3.

Dipole built around Hi-Q Balun center insulator. New, never been outside from the look of it. Stranded copper attached to center insulator. Looks like it was being built for 20 or maybe 30 meters (didn’t measure wire, just counted turns on the coils of wire and estimated). Two ceramic end insulators not yet attached to the wire ends. $9.
