Oh, hell no!!!!! And, only a matter of time before that idea pollutes on this side of the pond. Having a government and manufacturer decide what and where you can, not only transmit, but receive, and not just FREQ restraints, but restrictions on modes, sensitivity and selectivity adjustment, filtering, etc. And not just two-way radios, but stand alone receivers, smart phones, wi-fi radios, (Of which I use heavily.), security systems, various Part 15 devices, etc. Yeah, this is bad, bad, BAD, when you really contemplate of just the wide range the scope of this subject may cover. This is worth fighting and, putting our foot down on, and the sooner, the better. You think that the Communications Act that blocked scanners from 800MHz cell phone reception was bad? Wait until the ignorant, lobby hungry, legislative goon squads in Washington gets a hold of this. (And don't think that they won't.) Thanks for bringing this to light Chris!

Well, with a little over 100W PEP, +20dB preamp, and a tracking 2M boomer yagi, you can do the ultimate satellite, EME, and bounce yourself on the Moon. We certainly hope that won't end its life cycle too soon.

MW Loggings / The Reds loosing on 580WCHS radio.
« on: July 29, 2020, 2250 UTC »
I couldn't listen to Larry Elder where I was working Tuesday evening, (Since the usual 1410AM station local was off-air from that X3 T-storms the night before.), so I listened to 5kW 580WCHS when they switched to their directional array of beaming to the Atlantic Ocean. There, I listened to The Reds Baseball, and them loosing to the Cubs. Let me just say that listening to LIVE baseball, with no audience, just plain SUCKS! At least golfing has a clapping audience. Anyway, does everyone towards Roanoke and East RX 580WCHS well when they dump to the ocean at night?   https://radio-locator.com/info/WCHS-AM?loc=38.48830%2C-81.80511&locn=25159%20%28Poca%2C%20WV%29

Amateur Radio / Re: Amateur satellite operation

I did crossband FM UHF / VHF Sat contesting back in Summer 2006 ARRL Field Day with the Ontario County ARES Group. We used my then Alinco DR-620T to two separate beams, (One for UHF uplink, the other for VHF downlink.), and gained like 10 points that way. I've also done the UHF Mir Space Station Repeater from home. I've heard several STS calls on 145.550MHz FM and 145.800MHz, but couldn't beat the big-guns. I hear ISS on 145.800MHz on the scanner. I've yet to do SSB with crosslink via satellite, albeit I have the perfect rig to do so with a TS-2000X. I hope to try.

Huh... Well, having a back & forth e-mailing with Boomer answered my question of why RF Sun Bounce wasn't followed up after 1959. Satellite tech came into play. That said, political volatility today puts our birds into jeopardy. The SDI Research from the 1980's Reagan Administration certainly didn't end with the 80's, but other countries have followed suite, and satellite attacking could be happening right now, but never reported. Except, through alternative media. The Chinese, Russians, and don't count out Iran and North Korea, doing just that to our birds up there. So, if we do find that our birds are getting shot up, and thus we loose, GPS, broadcast links, and everyday COMM's, then Sun Bounce maybe an interesting alternative to consider again.

Equipment / The new Silphase R1 SDR receiver!
« on: July 28, 2020, 2043 UTC »
Huh... Just posting what I did just hours earlier about my $0.02 worth on the Icom IC-7300, then comes interesting news about this receiver,    https://swling.com/blog/2020/07/the-new-silphase-r1-sdr-receiver/     Looks like some interesting rigs coming out of Eastern Europe.

QST even called it a 'Game-changer' when the IC-7300 1st came out. And, everyone that I know that has one, around my area, really seems to love it. But, all around, check out the eham reviews,    https://www.eham.net/reviews/view-product?id=12742     I can tell you that the ones that I've heard on-air sounded fantastic, even on just the stock mic. As a stand-alone receiver, well... There are some picky ops out there that opted for the more expensive cousin, the IC-7610. I am eying that new portable QRP unit, the IC-705,   https://www.icomamerica.com/en/products/amateur/handheld/705/default.aspx    That looks like a sweet package of a rig. Has is finally met FCC approval, yet? I'm waiting for the reviews, and the glitches, that come from this, since I've been burned by buying the latest early, then find out the problems that come from it. Still, and SDR portable that covers from LW, MW, HF, VHF, and UHF, is a very tempting package to want to have. The transceiver that I'm really looking at, but won't be able to afford anytime soon, is the Kenwood TS-890S,  https://www.eham.net/reviews/view-product?id=14060    ,    https://www.kenwood.com/usa/com/amateur/ts-890s/      Yeah... I've always loved my Kenwoods, and am not parting with any of them anytime soon. (Me, bias??? Hmmmmmmm, yeah... More like spoiled by them.)


Ya know, of all the Part #15 kits that have been out there through the ages, none have been, or even still, talked about as much as this one. Folks are still kickin' themselves for getting rid of it, or when their parents did. People still want this today!
Heck... I'd still take one.

Well, the lower the FREQ's for 5G, the better, since I understood that the initial proposals were to have 5G anywhere from 24GHz to over 62GHz, with emitters from every few hundred feet, just bathing us in microwave RF in the millimeter region. So, I say the lower in FREQ's for that, the better. That said, I still believe that 5G will not penetrate where I am. Especially, with Summer foliage.

Equipment / Re: Quick and dirty 434 MHz 8 Element Yagi

Huh... Like the one that I made in the mid-80's to watch a PBS-TV translator that came in kick-ass in the winter on just a UHF Loop, but was severely attenuated in the Summer foliage. So, I needed something with a lot more gain on UHF TV CH56. And, that worked well. (Hmmmmmmmmmmm... I wonder whatever happened to that beam?) Anyway, how is your match on 432MHz is to hear 432.100MHz SSB and CW Amateur Radio stations and even 432MHz Propagational Beacons? Or, even 435MHz Amateur Satellites?     

The RF Workbench / Build a simple AF Sine Wave Generator.

Simple, sweet, and useful. Boomer wanted to see it, especially after he helped me get the values of the RC Filter right. (Saved me a trip of digging through my college text books.)     Go ahead and download and build with leftover parts.  https://archive.org/details/555-timer-adj-af-generator-schematic

The other thing is that they are tests, where someone just TX's and uses various on-line SDR's to actually see if they are getting out to various regions. I guess that beats calling a friend, or relative, DX'er that's out of state, or out of country, to see if they are getting out.

Well, you must have done so, since Radio Survivor just did a 'Follow-Up',     http://www.radiosurvivor.com/2020/07/20/confirmations-of-1700-am/

I would have thought that the radio hobbies would explode more as well, but that's not what I've noticed. I've actually noticed less Amateur Radio, CB, MURS, GMRS, and FRS, activities around me. Could be just the usually summer dulldoms, in which the radio hobbies will be active again this fall. Or, could be cancel culture, to where people are now just too afraid to say anything fearing a backlash. We'll see...

Part 15 AM and FM Station Operation / Re: Part 15 AM and FM
« on: July 22, 2020, 1903 UTC »
One passing contemplation here, (Not thought, as that would hurt too much.), would be to see if your AM TX is possible of even going 100% modulation. There's some cheap kits out there that struggle to do 50%, at best. Anyway to put that to an o'scope, or an off-air AM monitor VU meter, to see what a 1kHz test tone does when you vary the audio input level? Then again, just like most modern day CB's, there maybe a limiter in your TX to on purposely keep that level low, in order to boast Part #15 FCC compliance. (OK, that was a couple of contemplations.)
