Who pulled the plug on the propagation machine?

Wednesday, Oct. 28, 2020

So far this week, I’m batting .333 for my efforts to check in on my CW traffic net. Every night the band seems to go long at 9 p.m. Eastern time, and I can copy Texas, the upper Midwest and southern Florida, but not a station closer than 800 miles — which includes every NCS on my traffic net.

Yesterday the non-existent propagation was made worse by the SKCC Sprint that was taking place at 9 p.m. I could barely tell the NCS was there, so even without the sprint stations, I couldn’t have checked in. The situation tonight was much the same, minus the sprint stations.

CW FILTER NABBED! I was finally successful in my effort to land an original CW filter to install in my Heathkit SB-102. My external Daiwa audio filter works well; the problem is it still isn’t a good as an IF crystal filter. The Daiwa is a good replacement, but I kind of prefer the original forward-firing speaker in the SB-600 speaker/power supply. The Daiwa has a comparatively small built in speaker with good output; I might open the unit up so I can port the audio output to feed the original speaker.

Once the filter arrives, I’m going to get it installed ASAP; I’ll also remove the filter switch knob off the SB-102 on the bench and put it on the one I’m using. I finally found some scans of how the SB VFO dial and knob are properly assembled. A fellow restoring some SB 300/400 gear had some great scans from the manual and his own comments on tearing the VFO down and reinstalling the parts correctly. I have another SB-102 that had the bushing so dry the VFO wouldn’t turn; I pulled on the knob and I think the knob pulled out of the track it rides in on the VFO dial.

When I can get the SB-102 off my desk, I would like to take a look at the Swan 350 that receives well but has no transmit. I need to check some voltages, relays and maybe some tubes to track down the problem. It’s probably something simple — or so I hope.

WAITING FOR USPS. I’m still waiting for my Amphenol 2-pin connector, and I also picked up a complete assembly manual for an SB-101 (simply to have assembly instructions to properly reassemble the VFO dial and knob assembly.

On a whim, I also ended up with a successful low-ball offer on a Kenwood TS-520SE. I borrowed one of this rigs very early in my ham radio career, and thought a great deal of that radio. I’ve always wanted to have one, but passed by a great many good deals. This radio is a bit worse for wear, the cabinet really needs repainting. The front panel looks good, however. There’s also a VFO 520 currently on eBay, and I wouldn’t mind picking it up to go with the TS-520SE.

The rig is supposed to arrive by the weekend … but there’s no tracking offered, so I’m skeptical it will arrive on time. As cheap as I purchased the radio, if it is a basket case I can put it back on eBay and most likely make most or all of my money back.
