73 meters would be a much better choice this time of the night.  With the proliferation of cheap DDS kits on ebay, ditch the rocks.  Much better frequency stability and infinite frequency choices.

BTW if this is to turn into a technical discussion, it should probably be moved to the workbench forum.

Equipment / Re: 4:1 or 1:1 ? Neither?
« on: January 11, 2022, 0002 UTC »
4:1 is usually only used on a folded dipole, or any antenna with a higher feedpoint impedance.  A 1:1 balun should be used on your garden variety dipole.

As others have stated, it depends on where you are and who you are trying to reach.  You can use the VOA propagation tool to get an idea of where you can be heard with different power levels, antennas, and time of day, frequency, etc.   https://www.voacap.com/hf/ This is what I use to test various 'what if' questions.  Just remember, power stated is in PEP, not carrier.

Could be an intermod product.  Do you hear it during the day as well?

Got 'em here under a local noise blob that shows up every night at 1800  :-\
Heard some 'Dead Mans Party' at 0143, OM, then into Peter Gabriel's 'In Your Eyes'

Thanks for the entertainment!

Things have been going downhill lately with regard to the kiwis.  Lately I've seen the wspr daemon running up all the available slots on a few of my favorite sdr's.

Funny you should mention this, as I drove by that site last week.  I was in the area for work of course ::)  According to their website, they just bought a new Ampegon transmitter and are in the process of installing it.

The world went SMD in the 80's.  It's really not that bad once you have decent tools.  All my new projects are smd.

I have a keyboard that does that.  Only happens on 73 meters for some reason...  ::)

The 60 Hz buzz could be from an inverter powering the trucker's fridge & other appliances?

That's what I assume.

I notice this and other noises while passing semi's on the highway.  The clicking noise, and also strong 60Hz buzzes.

"Still lots to listen to" is the beat on the street.  James Careless wrote it and features Gilles Letourneau from the OfficialSWL Channel on Youtube.
