Trying to down-size a bit and these must go, as I will probably never use them again. All units are rack-mountable. Heavy stuff, only local pick-up (in Greely, just south of Ottawa) or can meet within an hour's drive of Ottawa. Value $160, take it all home for $100! 1. and 2. Two General Radio 1123-A digital synchronometers (clocks). Displays time HH:MM:SS. Requires input of 1 MHz or 100 kHz, sine or square wave. Can be synced by local clock pulse, with provision for propagation delay. One (black panel) was working fine when taken out of service. The other one (white panel) worked but did not reset at 23:59 (the old missing reset pulse problem). I never found time to fix it while the first one was working fine. These units are typical GR construction and work reliably, except that the display modules are a bit of a pain to keep working due to recurring contact problems (annual maintenance recommended). With photocopy of the manual and fold-out schematics in a binder. And a box of spare bulbs for the display modules. Needs GR-type power cord. $40 for the pair. 3. Fluke 207-13 VLF Receiver/Phase Comparator. * See Note. Phase comparison receiver, tunes 8.0-31.9 and 60.0 kHz. Local standard comparison input 100 kHz or 1 MHz. Modified antenna input circuit. Was working fine when taken out of service, and checked OK in recent "lash-up" test. With bound photocopy of manual with fold-out circuit diagrams, and a box of untested spare circuit cards from a cannibalized Fluke 207. $30. 4. Spectracom 8164 NBS Receiver/Disciplined Oscillator. * See Note. A 60 kHz phase comparison receiver. Local standard input 0.1, 1.0, 5.0, or 10.0 MHz. Modified to add 10 MHz, 100 kHz and 1 Hz TTL outputs, and to remove 12VDC from 10 MHz sine wave outputs (distribution amplifier) to remote sites. Was working fine when taken out of service when WWVB changed to phase modulation. With original manual and diagrams. $30. 5. Kinemetrics/TrueTime 60-TF LF Receiver/Frequency Comparator. * See Note. Phase comparison receiver for 60 kHz, compact construction (1.75-inch rack panel). Local standard comparison input 1 MHz but might work with others. Was working fine when taken out of service, and checked OK in recent "lash-up" test. Digital phase display and strip chart recorder on front, analog voltage output on rear. Unfortunately, no manual or other documentation. $20. 6. Beckman Instruments 905 WWV Receiver. HF AM receiver, all vacuum tubes, selectable channels 2.5, 5, 10, 15, 20, or 25 MHz, with fine tuning, audio filters, internal speaker, S-meter, modified for AGC voltage output on the rear (BNC). With photocopy of the manual and schematic. Working fine but power cord should be replaced. $20. 7. Lavoie LA-800D WWV Frequency Comparator. Compares local standard frequency (50 kHz to 10 MHz) with WWV on 5 or 15 MHz. Vacuum tubes. Scope trace is good but screen has small burn mark (does not affect operation). Tested with 1 and 10 MHz local standards and seems to be working fine, except there is no derived 400 kHz standard output (not needed). Probably needs alignment. When fed with a good local standard, it is fun to watch the phase changes on WWV signal caused by propagation. Big and heavy. With 19" cabinet and photocopy of operation and service manual. $20. * NOTE -- The VLF receivers do not work by themselves with the new WWVB signal format. You must first de-phase-modulate the raw 60 kHz WWVB signal to remove the PSK time code modulation before passing the signal to the receiver's antenna input. See the article at : http://maxmcarter.com/rubidium/2012_mod/index.html for one solution. Take all seven units for $100 cash. 73, ... Martin Potter VE3OAT

I would pay $250, via PayPal, including shipping, if you would ship the pile. If not, I would understand. I figured I had to at least give it a shot.

Hi There’s six pretty big gizmos there. My local UPS store would charge me $20 to $30 a box to pack each of them (and barely do an adequate job). Looking up shipping rates from here to there, each of the 6 packages would run about $70 to ship. Net would likely be in the $400 to $600 range. Yes, there’s a lot of guesswork in those numbers. They probably would go a bit cheaper via the post office.

Well that was fun looking up the radios and those are very fine prices. I agree with Bob that the heavier tube receivers will be a fair shipping charge. But as Martin wisely says come pick it up. Good luck to some lucky person. Regards Paul. WB8TSL On Sun, Feb 7, 2021 at 9:50 AM Bob kb8tq <kb8tq@n1k.org> wrote: > Hi > > There’s six pretty big gizmos there.
