WBR update

Posted Labels:
The WBR Receiver is now pulling in 60m SSB from W3, W4, G1, and elsewhere. Removed a single winding from each side of L1 and a tagalong cap (10 picofarad?) in parallel at C8. Maximum signal was achieved by grounding the antenna center conductor at its entry to the board. (The signal pot still has little or no influence, so something else may be amiss.)

Great to have the "new" ham band in the ears for the first time since privileges were granted.

Nice foundation for a 60m band plan. It will be a help while I try to sort out frequencies and tuning range.

At the top of my tuning range are NPR broadcasts carried on 5446.5 by American Forces Radio. AFR is just below some cross-Atlantic meteorological observations in a female voice.

Another useful resource via HFLINK.

Alerted by LA3ZA to 7N3WVM regen, which Sverre merged (PDF) with N1BYT's. Makoto suggests a ferrite bar antenna.

It's screwed to the case, but the case is still open. The signal pot was poorly soldered. Fixed that and removed the jumper from the antenna's center conductor to ground.

The intermittent antenna, still partly buried in frozen snow, disrupts my listening now.

The Elusive Subja Seed

Posted
Why am I so captivated by the idea of drinking tasteless, slippery, crunchy-kerneled seeds? Because subja seeds sound like fun. I first learned of them by browsing The Indian Spice Kitchen , where Monisha Bharadwaj describes them, but Osimum basilicum seeds seem impossible to find. I made a special trip to Seattle's Uwajimaya to track them down, but came up empty. I stopped at Market Spice at Pike Street, where they hadn't heard of them (but they suggested another shop down the street). I went into Souk, where the gentleman understood what I was looking for only after I described it; he knew the seeds by a different name, which he couldn't remember, and said his sister gets them at a shop (the name not in his memory) on Roosevelt Avenue. But I was out of time in the city and couldn't follow up. (But before I took more than a few steps out Souk's door, the proprietor called me back in, because he had asked his arriving friend what those seeds were called. Tukmaria, ...
