Hi Gary and Mark, My efforts to add varactor tuning to the FSL antenna haven't been abandoned, just put on hold. I gathered all the parts and scoured the Web for various circuits and approaches for using varactor tuning, to to reacquaint myself with the pros and cons of varactors, but that's it so far.
As usual I currently have a number of partly finished radio related projects going on, and I haven't returned to this one. Right now I'm working on wrapping up a LCD digital readout for a Sony ICF-EX5MK2, and also doing a LED mod to replace the backlighting lamps inside of a mint condition, vintage Zenith Trans-Oceanic I acquired. It's just a case of too much work and commuting! Retirement one day sounds nice :^) 73, Guy Atkins Puyallup, WA > > ---------- Forwarded message ---------- > From: [email protected] > To: Mailing list for the International Radio Club of America < > [email protected]> > Cc: > Date: Tue, 24 Nov 2015 04:40:06 +0000 (UTC) > Subject: Re: [IRCA] Puyallup, WA Ultralight TP's for 11-22 > > > Hometown buddy Guy Atkins has recently done some experimentation > attempting to adapt the standard FSL antenna to a varactor-tuned design for > inside-the-car DXing at the Oregon cliff sites, but apparently was > disappointed at the results.
