Broadcast Announcements / Re: Radio Pushka now on Shortwave 24/7
« on: April 25, 2020, 1723 UTC »
Sporadic-E skip on 26 MHz beginning NOW and all Summer on and off should help to make your signal heard much closer than the longer-distance (and not very frequent now!) F2 skip when Es happens - maybe within 200 miles or less if the Es MUF is into the FM-BCB, etc..  THANKS for this! I will be trying!! MB

Regarding the "Rocky" beacon's fence antenna: I should mention that about two weeks ago I moved the 1/4 wave "hot-side radiator" to the top-most barbed-wire cut to about 35 ft./12m in length (about 1/4 wave figuring in the NVIS type of radiator "low to the ground" and ground-effect capacitance to shorten it by at least 10% of the 468/Fq. in MHz/2  for the 1/4 wave (ft.) formula. 

This change seems to help a tad, as it is heard fine with "Rainy" on the KPH Point Reyes/Marin County, CA KiwiSDR (only 2 km east of where I extensively DXed LW/MW at North Beach in the early to mid-80s and a few times after). 

Rocky's ERP on ~6626.2 is still nowhere near the levels of the long-time 6700.4 "HexY2K" nor the co-channel "Rainy" ("ticker") beacon on 6626.2 kHz.

Those three beacons (Rainy/Rocky HexY2K) represent the stronger daytime desert-beacons I am still letting operate allegedly - I have not visited the other two beacons in over 13-15 years (I'm not doing much desert-travel these days save for more local trips and camping).

On ~4096.0 only the long-dasher "Coxie" remains as a daytimer (battery long DOA...) and ever-rare is MarinDit 24/7 (fundamental) about 4096.87 (< or = to about 5 mW ERP) is very hard to hear here - the only location I've ever heard it's fundamental is in Darwin, CA and a also few miles outside near Long's Well Wash while camping out 5 years ago - both times at morning dawn...

Just an update for this last weekend of April.  73 - SpM/MB

HF Beacons / Re: "HexY2k" Joshua Tree NP 6700.5 khz
« on: April 23, 2020, 0946 UTC »
Amazingly strong here in the southern Owens Valley in early April on a couple of desert-walks when I rolled out a "mini-Beverage" on the ground (mBOG) aimed toward the beacon's direction (southerly) and it was strong on peaks generally mid-day thanks to some decent shorter-skip on 6.7 MHz when a coronal-hole occurs, helping the MUF peak up a tad.  I've also recorded it via the KPH KiwiSDR (near where I extensively DXed MW and LW in the early to mid-80s) at Pt. Reyes North Beach. 

Via a few listens to KPH rx., I think 6700.4 Hexy2K is about 10dB stronger on peaks than the "Rocky" beacon fast-dashing on 6626.2 kHz (with its stronger paired beacon "Rainy") as it *does* have a good (in-clear) inverted-vee down there in the granite boulder land...

This is a link to a recent photo I took of the "Rocky" beacon - formerly located on a large rock pile 4 miles west of Darwin, CA; but due to a failed keying-cycle (RC circuit) cap. I removed it and after a repair I relocated it near Owens ('dry') Lake on a barbed wire fence antenna as shown.  The "hot" side is the second to the top wire, and the "ground" is the bottom-most wire (clip-leads visible). (About 150 dashes/minute).

The photo is here:



This is heard with the far-stronger "Rainy" beacon in the Mojave Nat. Preserve - Rainy has strong "ticking" sounds that vary in rate due to solar-incidence levels.

Both ~6626.2 kHz Rainy and Rocky are day-only and have been "paired" for about 13 years now...

One upon a time ago when the AM-BCB was not so log-jammed with an insane amount of NA stations (FCC overpopulation!) and before the Expanded-Band nonsense began (1620 to 1701 kHz), the FN beacons were amazing, along with skywave from FMing cordless phones - rec. in the south-Puna District Hawaii (Sept. 1989) recorded via an ICF-7600D and a 10m wire at Kamoamoa Campground in HVNP (now under lava) on a long 130 km bike ride from Hawaiian Acres.

PS: this does not mean "the end" of the 4096 units:  The former 'Viking' beacon (once 24/7 ~ drifting 4095.9) was later that day implanted in a far-safer location not near a frequently visited mine (in over-touristed Inyo Co. too close to LA and Vegas/etc.) nor near a road nor in a previous video.  It IS micro-powered and strictly a daytimer (ERP perhaps 5 mW max.).  Audible on friends SW radios via groundwave in a nearby teeny town over a desert ridge to observe solar-radiation levels (not my teeny ramshackle town tho - hey I am in zero debt with 750 FICO and don't pay the real-estate "lady" as 100% owned!).

Awaiting later in year (unless in mil-lockdown), to split CA and buy acreage for DX purposes in a FAR-QUIETER location than Inyo (OMG!)...

Only the long-dasher (with a chirp) "Coxie" remains on ~4096, daytime only--since 2001. ENjoy! 73...

HF Beacons / Re: "A" Beacon 2097 Returns
« on: March 27, 2020, 1537 UTC »
The Creator of the A beacon, due to a lot of excessive publicity, desires to likely QRT the unit and potentially the "Wind" unit, also... (FYI)

whoops alotta typos above posting but UALL figure it out, LOL-HI!

In the 11 minute Internet Archives recording posted just above, the highest pitched "dasher" is just a 4011 NAND gate keying into a dipole about 10 feet up facing southward/northward  and just 10 ft. above decomposed granite soil (amazing for RF properties and reflecting capabilities we KNOW too, now!).  It was located 10 miles SW of Lone Pine at the "Great Space Cneter" (Franklin Merril Wolfe)  . Just like Hexie in JTNP - like DG actually sewems to AMPLIFY HF beacon signals!! // etc.

Amazing 6700.5 still lives now 20 yrs... (Hexy2K which EdH and I pimpanted in 29 Dec. 1999 and hiked 3 miles back to White tank CG to "enjoy" the CG filled - up with Euro-Drunks and hige beer cups galore wishing the world to end Y2K stlye!  We laughed ""It has not happened in China" yet and it IS 2000 THERE, now, NO??? SO what is the fuss?

Anyway, we camped there to plant the 6700 unit and to enjoy a New Millenium Coming (OMG what if we knew now...!!!!).

anyway, 73 Jim etc. enjopy HF DX and the analogue mode... and via "the digital beast" here via HFU, too... ;-0

Need to state I will not comment on Jims recent e-sending to me re. my rather snarky attitude I extended toward him in my won misunderstanding. We both love this desert beacon stuff.  Just a bit of misunderstandings based upon (me thinks) mutual mis-understandings for which I will take 99% blame for.  I feel I have contributed a lot to the radio DX world out there, since I got into MW DX in 1972 with my father's panasonic radio I found in a closet in Marin County.  Thus this fascination began.

The desert beacon thing started with my implanting a 4096 beacon "the Little Beeper" in a remote fern canyon valley in marin County in Winter 1988, after transmitting with it from parent's house earlier.

I could hear its fading and second harmonic by day fading from 4 miles to he west.  The location was "fern canyon" 2 miles west of Loma Alta Hill in marin - my fave hitt to hike on and listen to natural radio in 1991 and beyond.

the creator of the "wind beacon" (then on 4095.5 kHz called "The Wind Beacon" NOT "windy" as thought today) - mainly the RF end of things (his friend does the IT stuff for the micro-pro and eprom it has to send the data and whom built the canteloupe spoon anenometer).  He implanted a 4096 beacon I first heard in Aug. 1996 from Glacier, WA at KG6EK/&'s QTH - Jim Ericson - a fellow at the centre (like WB6EER - Mike MIdeke) of the 1750 meter "LowFER group. I visiteed Jim coming back fro a 2 day car trip from tacoma, WA (where I was doing IT work at a hospital via a SF, CA based company) and got fed up with tacoma and went on a fast trip into BC and back via abbortsford to wash. and into Glacier Valle.  The 4096 ditter was great sign at dawn and I found out later it was a guy in Ca implanted it in AZ desert. Cool1 I did this in 1988-1989 in marin.  cool!

Hence began the 4096 beacons, and I moved to Lone Pine in 1997 and then had access to the bit Mojave desert to do my "radio art" hance the 4096 beacons that in their heydey certainly WERE amazing sounding.  The WIND BEACON was a part - down at the low end on 4095.5.

Might was well give a link:

https://archive.org/details/TheBestOfHawaiiMediumwaveamBroadcast-bandDx-86To91/4096_Desert_Beacons_Vs_in_eCA-seCA_nwAZ_sAZ-and_Rec_Near_Tecopa_Calif_02oct2001_evening_R1000-SPMcGreevy-n6nks-long-ver2-edit-eq.mp3

THAT was fun, and I asked the FCC vicariously to "tolerate this most unusual radio art/propagation study "(EdH the inventor of TCP/IP internet protocal was a cool guy I met a lot with in this...).

So FF to today.

Despite my earlier warning, I extend a full Olive Treet o jim whom HAS been a torch in this and a strange defendor of the "windy" beacon I know wholly about and it has been moved since 2001 anyway, so the pic was innocent  fully or else I would not have  protested and posted it on my own site, anyway, .. or WOR, anyway...

So... I have REACTIVATED "Rocky" fast dasher (about 120?) DPM) just near Keeler out side by a mile via a barbed wire fence "monopole" cut to 1/4 wave and the ground is a long length 1 foot under the 1/4 wave barbed wire "monopole" wire pointing N.W. - so teh best signal should be to the NW/SE from keeler.  I admit this cuz it is OK with our free nation (still!!!) FCC. OKay folks?  Time to ask for licensing of this cool project and get it out in the open and not "where is that signal at" wponder.  All of the cloak and adgger siliness is MOOT in-light of SDRs / TDoA DFing which the FCC and mil. have FAR past the Excalibur modes... OK???  Soon as Anything is put on, the system KNOWS where it is - satellite DFing stuff included as EdH told me about in detail in 1002-2003 that was in-opne anyway but DXerws and public back then knew little about.

So rorry Jim - OK? Keep up gud werk here at HFU.

66.26 Keeler (out of town by a mile) via barbed ire fence - pulled outta a place 4 miles west of DARWIN, CA since 2007, is back home and fixed again and on a NVIS antenna near Keeler abopiut 100 mW.. OKAY? no sekret.  FCC okay? BUST the AM band pattern and power cheaters galore instead rather than silly milli-watt beacons like in CO etc. just do not xmit, dear beaconeers, on mil freqs etc. NOR the ham bands, sullies! do it on blanks freqs done after careful monitoring and keep them low powered, folks!!!!..

It would help to know your QTH in the world a bit, as this freq. once had a couple of Aussie "RPH" stations (500 watts each) on 1629 kHz, often in the clear, and they were often audible almost North America-continent-wide!  Possibly that still? MB

« on: November 04, 2018, 1911 UTC »
Oh yeah I forgot to mention above... the Pierce JFET VFO ckt. in my Part-15, 1712 kHz AM xmtr. is isolated and stabilized by an LM7809 regulator - virtually NO osc. pull or voltage-variation-caused VFO drift that  could be often caused by to the rest of the xmtr. (esp. the final-amp. and audio amp.) pulling down the supply voltage, so quite stable except for slow temp. drifts... 73-MB

« on: November 04, 2018, 1858 UTC »
Chris,  At night I hear 1710 carriers - two beating, in the Moj. Desert.  Unfortunately, 1710 is RUINED by a grossly overmudulated (Freudian slip there?) and illegally-over-powered 1700 Baja Norte/TJ station blastering for San Diego with the ESPN "stuff" blaring away wideband at +125% modulation - thusly totally splattering at night, dusk and dawn, 1710 kHz!  (1610 has now a weird mash of wide-carriers obliterating the tizzies...) thus, 1710 kHz --very useless at night for even 100 feet good clean pt. 15 coverage, hence the slew-up to 1712 (more below) for the locals... one of a zillion nightly signals on the BCB...

But as such, I am running very occ. a 1712 kHz AM rig home brew--(WW2-surplus spotting osc. unit converted-VFO) Pierce JFET VFO ckt. - (2N3819) to a 2N3866 buffer to some 2SK-20-something p.a., but in AM mode with 200 ohms DC res. via chokes, (using your way cool "SQUID"  antenna xfmr. (OK at this level of power) for good ant. matching) and a  modulation xfmr. actually for 6.3 v tube-filiments, the thing is 100 mW great audio Q (FM-like quality with a xtal. receiver nearby!) to a 23 ft. vertical but surrounded by RF eating salt Cedar trees, so it truly has the maybe the FCC-sanctioned 1 to 2 (max!) block "clean coverage" by daytimes (but awfully-splattered at night by "megaphone modulation mode" power-cheater XE-blaster 1700 San Diego/TJ) .  ;-0   

- and I have DXed my ~1712 sig. out to 4 miles JBA audio daytimes, out on a nearby dry salty lake with high conductivity(!) -- legal and mellow, low power AM b'casting is fun for us AM DXers to the max.  -- but far better than the wee-pipsqueak-RF that the Radio Shack Umpteen-in-One kits as kiddies we had that went 20 feet (loopstick to loopstick DXing...). 

 (I obtained one via eBay, recently, as I had in '73...).  If somebody could tone-down the XE-blaster on 1700 out west, the 1710 LP freq. would be great...
