Looks like fun Jay. I know nothing about 500 KC sooooo... which sideband is used and what bandwidth would be optimal for listening there?

I'm hearing Bob quite well on the west loaded delta loop. Much better than the 75 meter dipole. Rob I'm running about 1.5 KHz bandwidth. Someone is just below him sending CW. Looks cool on the display. His signal is coming up as it gets later.

I've never listened down there before. There's quite a bit of stuff going on! At any rate, I picked out a few CW stations on or about 510 KC that are quite strong. The fades seem to be long and slow. The short attached mp3 is the ID for one that was floating in at about S-5: WD2XSH/5 which I believe is Dale KW1I.

I'm using an 85 foot triangular loop out at the treeline that's oriented for E-W reception. It seems to hear a few S-units stronger than the 190 foot center-fed.

I was on .511250 LSB. I don't hear him now. Maybe he is taking a break.
Really need something directive to the west to hear him well. When I go bidirectional the noise comes way up. I could barely hear him on the 75m dipole with all the noise.

Hi Jay,
I just tuned down and hear you and Bob chatting.  Time I tuned in was 11:02 PM EDT.  Its the first time I listened down on 500 Kc portion of the band and when I tied the feeders together on my 160M antenna both of you were coming in real well.  I was using my Ten Tec Jupiter as a receiver.

Amazing stuff down at that end of the spectrum. The fades are very long and slow.
Probably less selective fading at those low freqs.

You guys are having some fun down there. Thanks for posting the spark "re-transmission" Jay. That's something you don't hear every day and I have to admit that I kind of like the "tone" of it!

Yes Rob, the tone was very easy on the ears. Also nice to look at on the display. I didn't listen later crapped out after a long day of yard work.
The loaded delta loop really shines down on 600m. I think I am going to make them bigger. I was surprised with the improved signal to noise ratio.

Yeah, I confess to running out of steam early as well for the same reason as you. My loops aren't exactly potent performers down there, but I can hear well enough to keep me interested in tuning through the lower regions now and then. We need to do less yard work and more operating Frank.

Bob is planning to be operational again tonight at the top of the hour starting 0100Z ... unless there are thunderstorms in his area.

Thanks for the report Joe. Glad you were able to monitor the QSO. I'm planning to work Bob again tonight at 0100Z.

May be several other stations about so try tuning the range between about 470 and 515 kHz.

Rob

Just turn your noise blanker.  That should cover it

Directive antenna helps a lot more than a noise blanker

I listened during two hours during the first night, and couldn't hear anything here in Md.  Of course, I'm in an apartment with a pipsqueak antenna.
