General Radio Discussion / Youtube: Radio Workshop
« on: August 29, 2019, 2233 UTC »
Stumbled upon this guy. Some great vintage radio repair videos as well as fun stories of pirate radio in the 1960s in the UK.

Rabbit hole warning... you'll spend a lot of time watching these.   ;D

I enjoyed browsing this website. He even measured the current produced by the various materials used.

Bacon, BBQ, Beef, And More / Found a Numbers Station in my Fridge Today
« on: August 18, 2019, 2255 UTC »

Went looking for an afternoon snack today and found this sitting in the cheese drawer of my fridge. (I didn't buy it believe it or not.) I haven't tried it yet as other packages of cheese were already opened. Will report back.

The RF Workbench / Recommendations: Resistor and Capacitor Assortment Kits?
« on: August 17, 2019, 1432 UTC »
Looking to stock a new electronics bench in my workshop. Need decent hobbyist quality through hole parts. OK if in marked bags, don't need them in a parts box. Digikey seemed expensive, "Joe Know Electronics" on Amazon looked pretty good... any recommendations?

Need 1/4w resistor assortment, ceramic caps, and electrolytics with a decent number of common values. Some of the very inexpensive kits omit several key values and I don't want to have to test every part's value before I use it to see if it is within spec. :)

Equipment / AcuRite 02020 Portable Lightning Detector
« on: July 27, 2019, 1828 UTC »
I've been looking for an inexpensive lightning detector for a little while now. I decided to try this one out mainly because the price was low enough to take the risk:

https://www.amazon.com/gp/product/B00EO1H3X8/

I set it up a couple of days ago and placed it on the windowsill next to my NOAA WX alert radio and literally forgot about it. Today I was working in a room on the other side of the house and heard this strange beeping. I searched the house and found that the new lightning detector was going off. Since there was no expectation of storms forecasted and it was a beautiful sunny day I felt that I just wasted $30 on a piece of junk. I looked at https://www.lightningmaps.org/ to confirm my immediate condemnation of the device, and lo and behold, there were t-storms all over the place. Most were 15-30+ miles away but this little pocket detector was picking up most (95%) of the lightning strikes I saw on lightningmaps.org. IMPRESSIVE!

I wouldn't call this a life saving device but it will be good enough to warn me to disconnect my coax.

For Sale / Wanted / Barter / FS: Book - Russia in the Microphone Age: A History of Soviet Radio, 1919-1970 (O

Russia in the Microphone Age: A History of Soviet Radio, 1919-1970 (Oxford Studies in Medieval European History)


The story of radio begins alongside that of the Soviet state: Russia's first long-range transmission of the human voice occurred in 1919, during the civil war. Sound broadcasting was a medium of exceptional promise for this revolutionary regime. It could bring the Bolsheviks' message to the furthest corners of their enormous country. It had unprecedented impact: the voice of Moscow could now be wired into the very workplaces and living spaces of a population that was still only weakly literate.

Book is in excellent shape. Will ship media mail to US addresses. $20 shipped or suggest a trade!

Equipment / uBITX 3-30 MHz 10W SSB/CW Transceiver Kit - $109 until Xmas
« on: December 11, 2017, 1256 UTC »
Thought this might be of interest here. Not a true kit as the board is already assembled. You just need to supply a chassis and wire up the connectors. $109 (includes shipping) until Christmas, then it becomes $129.

The original BITX40 40m transceiver is a fun little transceiver and is easily hackable. I just ordered the uBITX to try it out.

From the website:

The µBITX is a general coverage HF SSB/CW transceiver kit with features you NEED for operating ease, convenience and versatility. It works from 3 MHz to 30 MHz, with up to 10 watts on SSB and CW with a very sensitive receiver. It features digital tuning, dual VFOs, RIT, CW Keyer and more.  The µBITX is a general coverage HF SSB/CW transceiver kit with features you demand for operating ease, convenience and versatility.

22 Meter Band HiFER Beacons / HHH - 13566.2 Testing
« on: December 09, 2017, 2005 UTC »
I'll leave this running for the weekend. Running into a non-resonant antenna at the moment just to test it out. Located near Connecticut / Massachusetts border. Please let me know if you copy it.

22 Meter Band HiFER Beacons / Coming Soon... Beacons VVV, HHH, and WOO
« on: December 02, 2017, 1752 UTC »
Just ordered three beacon boards from Chris that will hopefully be on the air soon. All will be solar powered, frequencies to be determined once they are built.

A dual beacon - VVV and HHH - will be at the same location near the CT/MA border. One with a vertical dipole, the other with a horizontal dipole. Doing this as a propagation experiment. It might be interesting to see how antenna polarity impacts reception over time.

WOO will be located in Worcester, MA. A friend is interested in building kits and we might as well get him hooked on HF radio while we are at it. :)

I've added these three beacons as pending in the HFU Wiki so we can coordinate callsigns and frequencies if anyone else is putting one on the air.

General Radio Discussion / Outback Comms and Online SDR
« on: October 28, 2017, 1114 UTC »
Any recommendation for an online SDR that is best located to receive Australian outback comms like the VKS737 network? Just wondering which one Down Under would be recommended as I have a non-techie, non-radio type person here locally who would like to listen. Hoping to sink the hook and get this person into radio as he is a 4x4 enthusiast.

Thanks!
