I'm similarly half way to DXCC and in Europe. WSJT has been exclusively in the 1838 segment and accounts for at least half of my DXCC total. We cannot use 1800-1810 here. Jim Miller j...@jtmiller.com wrote: I'm about half way to DXCC on 160 and looking for any way to move the needle. Most

Hi Brian Thanks for the quick reply! Has it been mostly JT65 or have you seen JT9 in use? Thanks again Jim ab3cv On Tue, Nov 11, 2014 at 5:33 AM, Brian Duffell topb...@planet3.freeuk.co.uk wrote: I'm similarly half way to DXCC and in Europe. WSJT has been exclusively in the 1838 segment

I have put up a 160 meter horizontal loop fed with 30 feet of 450 ohm feed line to my tuner. I have a Radioworks 4 to 1 balun. I am considering splicing into the feed line at 10 feet so I can run 20 feet of coax into the shack. Thoughts? I run a qrp plus on 160. Hi Kirk, Are you using

By looking at the panadapter on my flex 6500, I can see KEES; they're not even THAT strong, (around -40 dbm) but the crud is definitely there, only down about 30 db from the main signal. It takes multiple phone calls, emails, mean facebook posts, and text messages to KEES and the FCC to get

Of my 55 dxccs on topband, 48 are cw, 34 JT65 and only 11 are JT9. There seems little JT9 activity on 160 here. JT9 tends to overlap the JT65 segment as phone is often using the higher end. Quite a few europeans are calling CQ most evenings with few takers. W tends to start coming in around z

Kirk, I put up a large horizontal loop and can use it just about everywhere but since I have a Yagi for 20-6M, the loop gets used primarily on 160-30M. The loop I put up is about 1100 feet of wire in a square up 65 feet (supported by four 70 foot utility poles I planted in my field) fed with

Topband: Nintendo 3DS After Market Power Supply 160 meters RFI

This past weekend I encountered interference on 160 meters that I tracked down to a neighbors Nintendo 3DS after market power supply. Full details can be found on a simple website I created to document this case. My website URL is http://sites.google.com/site/3dspowersupplyrfi/ 73, Don Kirk
