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.

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.

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 / 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!

10/11 meters / Any businesses still use CB?
« on: June 23, 2017, 2125 UTC »
I know there are some local construction and freight yard related companies using CB since all the trucks that enter their property have a CB installed. Anyone ever hear any other types of business still using it?

Equipment / AFEDRI SDR-USB-HS VHF/SHF - Anyone?
« on: June 04, 2017, 1901 UTC »
Looking at the AFEDRI SDR-USB-HS VHF/SHF:

http://www.afedri-sdr.com/index.php/new-afedri-sdr-usb-hs-vhf-shf-description

I currently use the HF only version of this receiver and was wondering if anyone here uses the HF/VHF version? Are there any other receivers that can be accessed via Ethernet? I can listen to my Afedri on any computer in the house over the network. Don't have to be tied to one location which is a huge positive for me.
