I played a bit, mostly on 75m SSB. I worked SD in very heavy static so that was fun.
From Asheville,NC.

My point was to substitute a tuned loop for the input preselector. I built a 4 band preselector for 100kc to 30 mhz for use with an old sw radio that had poor image rejection performance. I used an fet to act as a small amount of gain but mostly as a high impedance load for the LC network and to dri...

I second the magnetic loop suggestion. I worked a guy on SSB one day on 60 meters
using a loop inside of his HOA restricted condo. He was using 50 watts and was s7 or so.
Much better than nothing and also portable so you can try it inside and on the balcony.

Thanks for posting this. I am going to try it without the varactor and use a single turn loop
instead of the network and see what kind of silly active loop I come up with. I will tune with a
variable capacitor across the loop.
I will let you know how it works!

I had wanted a new 10m rig for use in the car and I ordered an import rig. It was horrible. I only throw one in the car if I go up on the blue ridge parkway, But the import was so bad I returned it. I use an Icom 7200 for that now with a Wilson 5000 magnet mount tuned for lowest SWR on 28.400. I kee...

Maximum bang for the buck buy an SDR. For HF and LF use I own the Airspy HF+ Discovery and the SDRPLAY RSPDX. Both are excellent on HF with the Airspy being better for NDB beacon band work below the broadcast band. I use SDR Console to control both and typically use the RSPDX @ LIF showing a 2mhz wi...

Thank you so much for this! I have it stashed as a PDF now. I have looked for this before and could not
find it.
Again...Thank You!

Yes! This board is a great idea and I hope it really takes off.

I have heard great things about LOG antennas, but I can't use one here because my entire usable backyard is full
of radials for my sloping wire antenna to work against. On the upside the sloping wire works really well!

I like listening to aircraft fly across the pond on HF SSB. New york, Santa Maria, Gander, etc. My favorite of all time was listening to Africa. Khartoum, Cairo, Tripoli. I don't hear them anymore though. Less traffic? Who knows. I also like DXing NDBs below the broadcast band. I have a couple of SD...
