Re: Coming Soon

I have heard , both, great and lousy, as predictions for the coming Solar Cycle. Everyone seems to have a different way of estimating how this coming cycle will act. . So In the low sunspot years I spend more time on 160, 80 and 60 M , and if the sunspot count gets better I will be up on 15, 12 and ...

Re: Most distant AM/FM/TV signal you ever tuned in?

I think there are 9 towers left for 1500, It’s been a while since I’ve seen them. Also I remember being able to see WKNR’s towers from a distance at night and not being able to receive Keener 13 at all in the nighttime. And I can’t forget WJR’s one tower from Riverview, I was able to see that one at...

Re: Fighting Back To DX The FM BCB In SE Michigan (Or Elsewhere) Again

FM DXing I had a 4 element Yagi for FMBC and It did fine up only 30 ft. It got blown down in a storm about ten years ago ! My first DX antenna for FM was a half wave, foldled dipole, I made of TV Twinlead and tacked it to my bedroom celing , when I was a teenager, got many signals from As far south...

Re: FM Stations That Used To Be Listenable In SE MI, But Now Difficult Or Impossible

"Translators and "boosters" have really wrecked the FM DXing hobby. Also the sensitivity selectivity of many "Modern" receivers is not what it was in the high end old tube and some early solid state equipment.

Re: DX’ing The NOAA Weather Band.

I have heard many tropo openings where most of the NOAA channels were occupied by signals from around MI, OH and ON. Never thought to log the times and callsigns though :(

Re: The cost of FM Translators and LPFM Transmitters

Probably more than a high end Amateur Radio transceiver for a translator box. It has to have high freq stability and emmission purity and be able to run 24/7. Guessing $10-20 K for a 100 W unit. For a 1 kW LPFM transmitter maybe more than three times that. :shock: My estimates usually are way too lo...

Re: Most distant AM/FM/TV signal you ever tuned in?

How about best AM DX with a crystal set ?
I heard KXEL in Iowa and WCKY in Cinci on a crystal receiver, and well enough to connect to an audio amp and hear loud on a big HI-FI speaker ! :D

Re: Most distant AM/FM/TV signal you ever tuned in?

I also picked up KFI , from Detroit, with a '56 Ford Auto radio in the house with a 5 ft piece of wire as the antenna. ; This was in 1965. On the road , I had a GE superradio on a golf course at night on the Big Island and could hear stations from the west cost of US and Canada and American Samoa an...

Re: New Radio

I have had some small radios but the little loopstick inside just does not bring in many signals on AM ! BEST portable for AM is My GE "Superradio 2" that has a very large ferrite rod occupying a large portion of the large enclossure, and that works ! the superradio also has some good speakers that ...

Re: Are 50KW Clear Channel Stations in Jeopardy?

It used to be easy for clear channel signals to reach coast to coast but then the 750 mile non interference rule came along ! Now, even inside the 750 Mile "protected" area there is spill over from new stations sharing the channel. But even those that can reach a vast area are only using a few syndi...

Re: Aurora Borealis AM DX Pilots

Aurora was wiping out WWV on 15 MHz and up and boosting signal on 2.5 and 5 MHz yeaterday. Ham bands above 30M were gone and signals on 80 and 160M were good. Could have been some back scatter signals on 12 and 10M but nobody else seems to be trying. maybe good on 6M too but I have no gear working t...
