I bought a used HRO in 1957, at the age of 12. I had a newspaper route, and one of my customers sold it to me. The HRO came with 4 band plug-ins (if I remember correctly). USSR launched Sputnik on October 4, 1957, and I immediately took my HRO to art class, so we could hear Sputnik beep-beep-beep on 20 MHz as it passed overhead, every 90 minutes or so. Of course, I was given a lot of positive feedback, and the shock of USA playing 'catch-up' to the USSR, plus the money that poured into education, pushed me into electrical engineering.
Great radio, and sounded good, back in the 60's had that 19 Set as on your bench followed by 1155, it was totaly rewired in purple wire, but worked fine, then HRO. That was a while back 😀 enjoyable video thank you for the visit to the past.
A brilliant classic vintage receiver Justin. A friend of mine had one when I first started getting into listening to Amateur radio and I was very impressed. A must for the shack and this one looks in excellent condition. 73...David M0DAD.
I had one of these 30yrs ago inherited from an inlaw It had bandspread coils for 80 40 20 meter bands and had been recapped however the neon regulator mod for the L.O had not been done resulting in having to re tune ssb sigs when the wife turned on the electric shower
There is printed on a A4 paper something like used on a BC 221 frequency meter giving the frequency read out for the HRO. Some time ago I found the chart on the net published by a G4??? but it seems to have been taken down.
Great stuff. I have one just the same as that and with the "dog house" PSU. I've used it with a homebrew transmitter for some CW QSOs but my HRO spends most of its time on AM Broadcast listening duty. Is there a stamped serial number plate just next to the aerial terminals on that HRO? If so you could find out its manufacture date....late 1930s perhaps. 73.
What's the horizontal valve that's been added under the chassis? First receiver I had back in my youth - over 50 years ago. You know an HRO owner from the callouses that they develop on their hsnds changing the coil packs ! It's just pre-war and very many were used in listening posts feeding intercepts to Bletchley Patk.
