Learn about the wideband radio links setup to allow high reliability cross-channel teletype, facsimile and voice circuits. Telephony RF carrier and repeater and wideband FM Data equipment is covered, along with conventional radio gear.
I was Army SC brat in 50's and hung out at MARS station K2USA, which dad built and founded. Also the SC museum, so familiar w/these sets. But then went USAF and solid year of radio relay and 10KW tropo school. Learned the old trc24 ( korea version) plus FRC 39a 10kw and MRC 80 ( an ipdated TRC 24 w/ 1kw and preamp. Fun,very hi tech, 600 channels betwedn mountaintops in Turkey: 300+ miles, 99.9999% reliability. Then went to ECM/ radar then over to Army as WO-1. 21 years later retd as CW4. This training opened many doors as civilian. Nice show, am fan. 73 Karl WA2KBZ
Thanks for great videos. I love this and have memories of my after the war experience with old radio gear and my time as a cw operator in the army. I love to come back some day on the radio after more than 40 years of silence. Trying to fix my old gear but it is not easy. What I have is not bad but needs recap and alignment. Hope to get you some day. 73
Hello Mike, thank you for this wonderful video. I knew nothing about the use of FDM and wide band FM equipment on D-Day. I used to be employed as a fax engineer by Muirhead, who were the only British manufacturers of fax equipment, so I'm really looking forward to episode 2. I always love your videos Mike. 73s from GW8JHT 👍
Living in England, D day has been a large part of the news recently As it is probably the last time that surviving D day military personnel will cross the channel to remember the battle and the fallen. Thanks for this very interesting series which explores and area not much documented generally. Thanks, Mike. 👍
Great job presenting this forgotten radio history!...Very clearly explained!!...Maybe you could include some background on the Fred Link Corporation in your next video!!!...Where can one obtain the War Department Technical Manuals that you’re referencing?
Mike, this is very interesting history of the technical aspects of the radio and telephone communications used in WWII! What was done to utilise the bandwidth on twisted pair is now days used to carry internet data (and the regular phone voice), via what's known as DSL.
I used, in Vietnam carrier equipment: 31M20 MOS VHF operator, 60Kc wide band VHF/UHF Transmitter receiver AN-TRC-24, and the carrier equipment AN-TRC-7, 12-channel phone and teletype (also see Communication shelter AN-MCC-69) Gen set two 10KW SF-10
Thanks for this video, Mike. This was a fascinating watch. I've seen pieces of this system for sale at places like Fair Radio but this ties it all together. I'll definitely be around for the future installments.
My grandfather was a radio man in D Day... My dads call sign was N3HW... I grew up to Morse code and CQ CQ CQ November 3 hotel whiskey radio contest weekend blasting through every TV and radio in the house and in the neighborhood.... Everyone knew when it was a radio contest weekend.... Great video 73s Do you think the air ships were used for a capacitor drawing atmospheric electricity?
Mike, thank you for highlighting this topic. It is something that I don't think anyone understands or has any idea of. We are all happy to applaud the work that was done to crack Enigma, but the leading edge science and technology that was applied to warfare is not in the public's eye. You could take the view that the comms systems that were used on D-Day were just as important as Bletchley in some ways as if they hadn't have performed, the outcome may have been completely opposite. OK, I do have an axe to grind having always been interested in communications.....:) Another epic series in the making! 73 de Richard M0SNR
When I first started working at the WEDU transmitter (channel 3) {in 1963} we has a FM tank radio set there and at both studios on 26.11 and 26.45 MHz (on an "intercity broadcast link" band) with a vertical dipole one hundred feet up the tower. All had H.M. AC power supplies. Worked great. Ron W4BIN
The first use of this surplus FM gear in the late 50's was in the TV broadcast business, both for audio assist on the lower band you mentioned and later for studio transmission links at 60 kHz Deviation in its extended modulation setting, which allowed early video rates.
This is very familiar! I got an MOS of 32E20 (Fixed plant carrier repairman) at Fort Monmouth in 1975. Most of the racks of equipment will trained on still used tubes, but they did use Collins mechanical filters.
Did a radio operator have to write backwards in early radio transmission? I recall my dad talking about early transmissions came in backwards and his father could write backwards?
Hi, good video, thanks! SSB is never mentioned, as if it had never existed? Moreover the signal appears as "encrypted" on a regular AM receiver. That would be a plus during war time operations?
