If so, this would be a simple fix when necessary. Just a thought ! Best of luck with the new rig.<br />Maurice G4DVM.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-953397841255562532.post-66211287245749923172009-10-07T03:37:24.784+01:002009-10-07T03:37:24.784+01:00I'm thinking you could make a circuit to look ...I'm thinking you could make a circuit to look at the voltage on the paddle contacts and drive a transistor for a TX switching signal.<br /><br />For the clipping problem, I'm wondering if a 10 dB attenuator in the front end would help. You could use a relay driven by the TX switching signal circuit to switch it out during transmit, or perhaps there's a way to do it with diodes.<br /><br />72<br />Goody<br />K3NGgoodyhttps://www.blogger.com/profile/09068811388940491546noreply@blogger.comtag:blogger.com,1999:blog-953397841255562532.post-35996183977733464522009-10-06T22:56:09.967+01:002009-10-06T22:56:09.967+01:00I like the idea of a neat little rig for walking/c...I like the idea of a neat little rig for walking/camping trips and holidays. Your new HB-1A QRP rig looks well worth the cash and now you have had some good results I bet it would be very good out and about. <br /><br />Enjoy your tinkering in test mode!MØYKS Simonhttps://www.blogger.com/profile/16843311894630055964noreply@blogger.com
