European AM

[Steve - WB3HUZ]

The propagation was good on 80 Meters this morning but some QRN. Was able to work F6AQK - John in southeastern France. He was very Q5 as you can hear from the audio clip.

Nice recording Steve!
I (pe1mph) wasn't qrv this morning.

By the way: John = Jean

Hope to hear you on 3705 'soon' in my qth,

Indeed! He always has the strongest signal on 3705. Must be the wine!

Hope to hear you soon.

More audio from Jean (even better signal on this one).

I've heard Jean nearly S9 at times in VT, while only getting bits and pieces from Henk and the fellow in Wales. Being at the bottom of the hill surrounded by mountains and noisy streetlights might have had something to do with it.

Looking forward to trying it from a more favorable (quiet/flatter) location this winter.

I worked a couple of stations at 2 PM yesterday on 3875 and uncle Al was on 3885. VTP is my neighbor here in manchester NH - not really DX. 10 kc spacing is about right to prevent AM QRM (if the transmitter is working correctly) and 15 kc is better...

Todd - Hearing any Euro-AM last night?

Anyway, I was on the OMRN net at 9PM which is a low power CW net that has check ins by guys with military sets. It is a slow CW net. For a change I used my two tube regen in the RX position instead of the R-390A.

For fun, at 10 PM I tuned south into the DX window and heard a station calling and working stateside. I clunked in with the 20 Watts on my ARC-5. He answered on the third try and gave me a 559. It was ES1WN, August (yes that is his name) using the Tallanin contest station in Estonia. T

he regen was doing a good job but more importantly, the band is in good shape for DX! It is quiet and seems to have settled down for the winter.

Thanks again.
I sent recording to Jean.

I'm still not able to read any European signals so far this season because of the power line noise (sucks!).  With the 110' high transmitting dipole which is broadside to the northeast US and Europe, I hear no noise whatever, but the Euros are right at the noise level.  With the beverage, the Euros are much stronger, but the line noise wipes them out.  The power line in question (three phases) is about a half mile from here, but passes right in front the boresight of the beverage.  I have tried to track down the source with portable receivers, but it is of uniform strength over about a 2-mile stretch of road, from 80m all the way through 29.999 mHz, and even in the 110 mHz AM aircraft band, with no peaks or dips in strength along the way.  Interestingly, it is barely audible on 160m, even using the beverage, and scanning through HF there are peaks and dips as a  function of frequency, but not of physical location.  The 75A4 noise limiter takes some of the noise out on strong signals, but is ineffective with signals near the noise floor of the band.

Without first pinpointing the source, I know from previous experience that it would be futile to try to get the power company to fix it, even if they bothered to come out and attempt.

Hi Don.  How do you know the source of the noise is the "power line" ? 

Here's a website that has a collection of recordings of various sources of RF interference.  Some of the sources have been identified and maybe something here will sound familiar.

Can you post a recording of your noise here ?

Yes, it is getting better - less QRN mostly. But the band is good for DX pretty much year around. I've been working Euros several hours before my sunset for several months now. Working them on AM is more fun though.
