What a horrible thing to do to a RA1000. :-( Better to put up a tuned antenna, and restore the RA1000 to service. :-)

It was one of the few that used push pull 833As in the RF, and had a symmetric tank with a huge inductor having a small motorized variometer (link coil) in the center for the antenna connection, and a split variable capacitor. The inductor was for AM band, so it has enough L to work down to 160 as well. Keep an eye open for RA1000s getting dumped, not too many left. > 73 > John > K5PRO > ______________________________________________________________ > AMRadio mailing list > List Rules (must read!): http://w5ami.net/amradiofaq.html > List Home: http://mailman.qth.net/mailman/listinfo/amradio > Partner Website: http://www.amfone.net > Help: http://mailman.qth.net/mmfaq.html > Post: mailto:[email protected] > To unsubscribe, send an email to [EMAIL PROTECTED] with > the word unsubscribe in the message body. ______________________________________________________________ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:[email protected] To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.
