This is true however, it should be interesting to see power company behavior going forward as the FCC has recently ruled costs for finding source interference must be borne by THEM! Pete W2PM The bes
One thing that really got their attention here was when I wrote to the local PTA and CC'd the newspape regarding the "radiation off the power lines" which run past a grammar school. Its been measured
Nice work and good comparisons. However I think it's important to note that noise nulling effectiveness is subject to local conditions which encorporate TONS of variables, and variables of variables.
I've used edgers and they create a nice slice in the ground but it's still a chore to run the radials in same without staples. So I just staple the wires to the ground now in a grassy area. The lawnm
Here in NJ normal lawn grasses will completely swallow the radials next spring using the ground staples. But normal lawn maintenance will rip many up. Raking and even lawn aeration will cause damage.
There is person who is also a ham who sells radial staples -- they work very well and are dirt cheap -- something like $7 USD for a 1/2 pound bag of 315 pcs. He is (or was) on Ebay but his email is:
Ive done something similar here by adding an MFJ 959C Preamp/Antenna Tuner. It's a nice preamp with ability to bypass, a simple L tuner with tunable inductance and C, a gain control for the preamp, b
I don't disagree with Herb here on the value of that type of loop, but if the problem is strong local line noise, or any other type of local noise (the list is long but can include jacuzzi thermostat
Another bad actor with household noise which will hurt 160 and even higher bands are water bed warmers. Found several already for friends over the years. Noise is pulsed white noise or other pulsed c
A neat program I use to do that here (and I have TONS of opportunities to have to profile the noise) is Zelscope - which runs in Windows and uses the soundcard interface you might already have on you
The so called (poorly) "magnetic loop" only works when it IS small - .1 wavelength maximum but that is not the optimal size.. According to several texts that should be .037 wavel. which is the 5 ft d
A station signing this call on 40M and working folks (work first/ask second) just said QSY to 160M. HB9AMO was in HH during the earth quake. Anyone know if this is for real? I found this website:
work on 80, 40 30, & 20meters. Hello Jim, I'm a pretty new user of antenna modeling software, but let me take a crack at answering your question and lets see how it corresponds to other responses you
A big loss to the DX and general ham community. Rest in peace. Pete W2PM _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
I would only wonder how well the rear null would actually perform in that scenario. Certainly putting the null to the local noise is a good thing, and the opposite would be absurd, but typically beve
I have found a beverage in the woods especially in a suburban area are very problematic physically as someone always seems to wander across it and take it down. I've since used bogs very successfully
I note that N7DF QTH is very close to high mountains to his northeast and east. I wonder the results of very long angle antennas to dx (EU) in that direction? 73 Pete W2PM Sent from my iPad _________
A few years ago the banter on this list often was in reference to the material in the ON4UN book and it surprises me so many here now don't seem to have it or use it. It is truly the bible of 160 met
New and used hardline connectors, and hardline is often available on ebay and often less than hamfest fare. And you don't have to dig thru vendor boxes with the spilled coffee and cigarette butts. Se
There are many good ideas including placing compact receive antennas like a pennant or flag on the fringe of your property away from as much man made sources as possible. However once near instant tr
