I still have the WWVB/60kHz shielded loop antenna that I made for it and although it is big, at about 30" x 30" x 2" or so, I believe it will ship FedEx or UPS OK. It's free to anyone who'll pay the shipping. It's made out of copper pipe and works quite well, and is tuned for the 5842 at 60kHz. > > Best, > Dick Moore > > > On Oct 1, 2010, at 3:50 PM, time-nuts-requ...@febo.com wrote: > > > > Message: 5 > > Date: Fri, 01 Oct 2010 16:34:57 -0600 > > From: ziggy9 <zig...@pumpkinbrook.com> > > Subject: [time-nuts] Possibly OT - Any interest in a vintage HP/Dymec > > DY-5842 VLF receiver? > > To: <time-nuts@febo.com> > > Message-ID: <990bd60b3c5d084910c10c8855912...@pumpkinbrook.com> > > Content-Type: text/plain; charset=UTF-8 > > > > > > Fellow time-nuts: > > I've got a circa 1964 DY-5842 VLF receiver.
