Rolled up the sleeves today and disected the MA160 looking for possible causes to decreased SWR-slightly loose ground nuts holding the radials to the ground bars caused the minimum SWR to lower as th
Not going with hairpin match- The UnUn has been awesome- Measured at the feed-point, my resonant point is at 1.818Mhz and the SWR 1:5:1 now using it to match the antenna and coax line-- Using 50 feet
Worked VK3ZL this morning twice, 100 watts, Pro III, and MA160V, for a new distance record from this QTH of 8,915 miles according to www.qrz.com calculations- I know...I know....not the toughest path
I have a good friend who has a 1/4 wave 80 foot vertical (63 feet) who decided to put a 100 foot coil to bottom feed the antenna for 160M. Using a tuner, (no UnUN) he is resonant at 1.830 but the sig
Dan, We have this exact set up at our QTH (W0ANT and N0AH). The K9AY loop is a single wire (east/west) and works very, very well. Last year, we had close to 500 Q's in both the ARRL and CQ 160 contes
With the MA160V, TS590S, 100 watts and and the K9AY single loop, worked S51V, G3XGC and G3OLB from our backyard lot..... Tonight was fb- G3OLB was moving the meter between 3-5 for a few minutes with
I think I speak for many when the real issue is adjacent digital QRM at or near the edge of 1.835MHz. There is much less CW from 1.840MHz-1.850Mhz. If antenna tuning issues are the main problem, why
meanwhile, digital mode operators continue to make swiss cheese out of our traditional CW DX spectrum on 40-160M........but if I bring this up, I get hate mail.......going to help a friend with an an
It would be great if a firm volunteer band plan would be created and supported to spare us all the grief of overlapping modes- One that would be up to date on today's technology and various internati
Dave, This is a great topic as there are a lot of us on small lots active on topband needing what ever edge we can find....... Do you have this loop you've designed published where we can see it? I k
Hello all, Not much to report on the low bands except 30M is hopping- I was hoping to get some new DXCC credits during April but no new catches for me here in Colorado. I did start a new yahoo group
Gull Winged raised radials cut to resonance seem to be excellent above ground radials- But I am in a small yard, and have my MA160V hooked up to radials going all over the yard, buried, of various le
Not hearing a lot this season, yet, on topband or much at all on 80M either- at least from DM79 using our backyard Cushcraft MA series verticals and K9AY loop, LP, with the TS590S- Really night and d
Not to get off topic but the ops calling cq test in the dx window last night ... That stinks for the rest of us. As for skimmer, I am taking the mentality of "are we suppose to disallow DSP filters t

RF/IP will save amateur radio. It is a HUGE industry and is growing by leaps and bounds. School's are ridiculously slow in getting RF into standard STEM curriculum but it will happen. Kids already us

Rick, what are the ball park figured on the coil diameter???? I'm guessing 5 or so inches across is a good place to start Paul. N0AH Sent with AquaMail for Android http://www.aqua-mail.com __________
There were ops all over the FT8 segments, refused to even try and work them and some were some pretty rare mults for CQWWCW...gentleman agreements are of the past.....sucks PAUL. N0aH Get Outlook for
When I had a 2 acre 80 meter 4 sqr raxial field up in Wyoming, this was strongly discouraged due to cancellation of currents, and went with the traditional 120 1/4 wave radials using a copper busline
