Yeah, when I heard about 8/20/2018 being National Radio Day, 1:, SFW?, 2:, Who thinks this crap up?, and 3:, WTFC? Well, I guess that we do, so here's the site about it, www.nationalradioday.com    Anyway, I believe that most of us are doing our part.

Equipment / No DRM around? Roll your own!
« on: August 14, 2018, 1538 UTC »
I was looking at this European company for their AM C-QUAM TX's, but found a neat DRM milliwatt transmitter,  http://www.aspisys.com/drmax.htm  So, if we don't have DRM here yet, we can literally roll our own Part #15-wise.

Yeah!!!! I remember those car radio FM to AM radio tuner converters from the 70's and even the early 1980's. Well, here's a portable one.   https://radiojayallen.com/cuthbert-fm-to-am-converter-mkii/    Radio Jay did a miss print there where he typed 15kHz, 14kHz - 16kHz, to really mean 1500kHz and 1400kHz - 1600Khz. (But gee, wouldn't super ELF be a neat kit to modulate? Hi-hi...) Anyway, what would you use this kit for? Most of you have SWL rigs and HF transceivers that do not have the FM BC band. This would be a unique way to add that. Well, sounds fun...

This makes it the smallest, and most affordable AM/FM HD radio out there yet. And, even if you don't give a flying crap about AM / FM HD Radio in North America, you've got to admit that, at the very least, it is intriguing.     https://radiojayallen.com/sangean-hdr-14-compact-am-fm-hd-radio/

Yep, I've already signed up for my channel. It's going to be called Real Video. Grab your channel now!   https://real.video/    I'm not suggesting that Youtube's days are numbered, but it's always nice to know that there's another games in town to check out. Launch day for this service is suppose to be this July 4th, 2018. Check it out!!!!!!! I've asked if they have any PSA's, or any other radio promotional, for air. If so, I'll add the link.

FM DX Loggings / FM Sporadic "E" is back!
« on: June 21, 2018, 0301 UTC »
COOL!!! Around 6PM my time, a friend TEXT'ed that he DX'ed a 95.1FM station from Manitoba today on his car stereo! Manitoba to Charleston, WV isn't a bad "E" haul. Now, if we can only get that propagation this weekend for Field Day 2018.

412
Yeah!!!!! Finally!!! A Part #15 AM Stereo C-QUAM kit!      https://radiojayallen.com/cuthbert-am-stereo-c-quam-transmitter/    Question is, will this be a come 'n go sort of thing, or will it be a neat Part #15 buzz that can help give LPAM and C-QUAM stereo a kick where it needs it? Time will tell. The sad part is that it may end up being that there will be more AM stereo transmitters than receivers out there. However, there are kits out there for converting you favorite stereo tuner, or receiver, to have C-QUAM ability, like this site,     http://meduci.com/

Huh... Looks like Hamvention, the world's largest Hamfest, has a Part #15 AM station operating there. When you 1st goto this page,  http://hamvention.org/   you'll see, "Tune to 1620 AM for important Hamvention updates." COOL!!!!!

Equipment / Radio Jay's AM Portable 2018 Shootout!
« on: April 27, 2018, 1719 UTC »
Busy AM radio Friday for me, then comes news that Radio Jay Allen updated his AM Radio Shootout,     https://radiojayallen.com/am-portables-mega-shootout-2016-update/      WARNING!!!!! The following maybe a fun read! Yeah, Radio Jay doesn't use measured spec's in his write-ups, but then again the average Joe / Jane may make more sense of these.

General Radio Discussion / LPAM proposals, studies, and map.
« on: April 27, 2018, 1659 UTC »
Neat link to check out the somewhat growing interest in an expanded licensed LPAM movement. I say expanded, since we have a working (Watered down.), LPAM model in TIS stations. Then, you have Part #15 AM stations. All covered via this page and links,   http://recnet.com/?q=lpam    In my mind, LPAM could cover as well, if not better than LPFM in various areas, especially Geographically filtered areas, (a.k.a. hills and valleys.). What do ya think? I still believe that a 10W LPAM station would work in various areas. I still say, if the FCC wants AM Revitalization, let us have it! (Thank you Boomer for sharing this info!)

One big problem with these new AM stationed FM translators is that they've put them on FREQ's where out of town stations have come in just fine. Oh sure, on paper with the 1mV/M contours they may seem fine and clear, but most of us know that FM stations go well beyond that. This morning, while listening to the WCHS 580AM Charleston, WV FM translator, that country bumpkin blow torch station from Williamson, WV was popping through this morning. A station well over 100 miles south of me, in my very bad FM direction geographically. So, you can't stop tropo propagation, even with a well crowded FM dial. Just more RF crap to skip over when conditions have it. Damn, I miss FM DX'ing some 30 years ago.

Ripped from The FRN.net,       http://www.frn.net/vines/read.php?3,6295,6295   Hope he pulls through!

      Yeah, the move in some CB communities is to go from CB to the license-free 5 channel VHF MURS band,    https://www.itstactical.com/digicom/comms/the-best-kept-secret-in-radio-communication/   I've been into it since 2002. Many CB'ers (That know about it.), are doing dual 27MHz CB and MURS. Most do it for the variety, get away from F2 and E-Skip, and to get away from 27MHz CB jerks. MURS can skip though, via temperature inversions. Not really thousands of miles, but more like hundreds. The same time that you notice distant NOAA Weather 162MHz stations, TV stations, and FM broadcast stations, MURS DX is possible. Case in point, on some early mornings, a friend of mine near the PA border would be able to talk to Buffalo, NY stations on MURS CH1. In Canada, I don't think that they have MURS, yet. (It's been proposed up there.), but at times the London, ON, Canada ambulance dispatch can be heard on our MURS CH3 well over 200 miles away. Legally, at 2W out, using LMR400 coax, and putting that VHF antenna above the tree line, you can possibly get +20 miles out base to base. If you are a hill topper, sky's the limit in range. Even if you are not up in the clouds waving HI to airplanes, flat terrain, a wide-open valley, near the shore of a large lake, or sea, you can expect some decent ranges there. Yeah, there's activity still in the license-free UHF FRS band, like kids, hunters, traffic routing in constructions, etc., but most folks believe that they only go as far as you can throw them. And, depending on where you use them, that can be true. MURS does penetrate foliage better than FRS, albeit not much. So, my question is, who's using MURS around you? (Besides Walmart on CH's 4 and 5.) Maybe we should have an open thread on the MURS band? Passing thoughts here.

Not that it will work for anyone outside of S. Korea, but is there a listing of the FREQ's and modes that's used by the Olympic IOC?
