A couple years ago I purchased a CV591A which also works well, but not any better than the HC10.Roger K7DDG  -----Original Message-----From: Roy Morgan <k1lky68 at gmail.com>To: Ed G <ed.n3cw at gmail.com>Cc: r-390 at mailman.qth.net <r-390 at mailman.qth.net>Sent: Tue, May 12, 2020 9:16 pmSubject: Re: [R-390] Filter Bandwidth QuestionEd,<Spoof mode ON>That HC-10 is just going to cause you frustration and confusion with all those knobs and so on.  Just send to me and I’ll save you lot of trouble.  I'll pay shipping.<Spoof mode OFF>With some luck, I still have the HC-10 I used to have, buried in the storage unit I am a long distance from now.As I remember the thing ran quite hot.  I plan to put a fan on top of mine (small muffin fan with rubber feet on each corner) for a no-modification cooling system.  You might check filament voltage and decide that a line bucking transformer is in order, for that and the R-390ADo enjoy learning and using it.  Roy> On May 12, 2020, at 9:39 AM, Ed G <ed.n3cw at gmail.com> wrote:> > Thanks all for the comments on my filter question.  Spent more time this morning with the 390A…I am thinking now the issue is basically pilot error.  I had been listening with a fairly new-to-me Hammarlund HC-10 being fed from the 390A IF output.  ……Roy MorganK1LKY since 1958k1lky68 at gmail.com______________________________________________________________R-390 mailing listHome: http://mailman.qth.net/mailman/listinfo/r-390Help: http://mailman.qth.net/mmfaq.htmPost: mailto:R-390 at mailman.qth.netThis list hosted by: http://www.qsl.netPlease help support this email list: http://www.qsl.net/donate.html______________________________________________________________R-390 mailing listHome: http://mailman.qth.net/mailman/listinfo/r-390Help: http://mailman.qth.net/mmfaq.htmPost: mailto:R-390 at mailman.qth.netThis list hosted by: http://www.qsl.netPlease help support this email list: http://www.qsl.net/donate.html
