I recognize that style shirt, used to have one just like it. When I build stuff now days, I do it in my recliner, reclined to almost laying down, it's a pain thing following 5 major surgeries trying to repair my spine after an auto accident while chasing a drunk driver. At any rate those shirts melt when solder drips on them, the one I had developed so many holes my wonderful wife of 51 years decided it was time to take it out of service. It now serves as several nice cleaning cloths. I am a rather large man and the shirt was a 3X so there was a LOT of material left that didn't have melt holes in it. Thanks for the diversion, I am still caring for my wonderful wife as the cancer eats away at her organs, her hair has now gone almost completely from the Chemo, the doctors have put her on morphine for pain as well as some other pain meds for breakthrough pain. The meds have helped her a lot, she has been able to keep food down once more and is gaining some strength. Docs say she has perhaps a year, two at the most, however she will be in a nursing home soon because her body will no longer be in any condition that allows my daughter and I to continue to care for her. I dread that time. You see other then a year that I was in Vietnam and the 2 years that I went to college, we have been together, and very close, even when I was in college, I would drive home for weekends, even in the worst weather to be with her. Getting old sucks.

You just "discovered" the effect that was used with the original Select-A-Tenna. Externally coupling a loop to add sensitivity and selectivity to a radio. Did you notice how the weak signal became much stronger? I have one and have used it both as an signal booster and as a notch to an adjacent stronger interfering station.

My parents in 1960 bought the predecesssor to this radio, same general case and knobs but with battery-tubes. It needed a 90 and a 7.5 volt battery. Your replacement silicon transistor probably has too much gain and bandwidth so it wants to oscillate at various spurious frequencies. I would try adding a 1K resistor in the base lead and see if that quiets down its tendencies. Or if you have some, try a ferrite bead or two.

[@annaplojharova1400]

The correct way to rebias for other transistor type is to match the emitter voltage, so the bias current. The reason is, the transconductance of transistor is Ie/(kT/q), regardless if it is Si, Ge, GaAs or any other. And this transconductance is, what the rest of the radio circuit is designed for (impedance seen by the oscillator feedback is exactly reverse of that transconductance,...). So with 0.6V noted in the schematic for the emitter, minus about 300mV of the typical oscillator amplitude, plus the Vbe of the transistor gives what needs to be at the base. So with 0.2V Vbe germanium it is the 0.5V, with 0.6V Si you may start with about 0.9V. But the emitter voltage needs to be checked and the bias readjusted (with the oscillator running of course).

Very interesting video, good work as always ! 21:20 the alignment should not be so touchy, perhaps you have to change the value of both of base-BIAS-Resistors and perhaps the transistor oscillates on another frequency (parasite oscillating 27:35) because these VHF/UHF-Transistors are much too hot for such stages! Some of them has to have a little ferrite-core on the Kollektor to prevent them from this parasite-oscillating. Perhaps another Type of Transistor is better, for instance a BF224, these are used in combined 455kc/10.7Mc-IF-stages... In my self-built superhet radios the biasing of the mixing or oscillator-stage is by far not that touchy.

Silicon RF transistors often go crazy on autoconverter circuits for MW radio, they have too much bandwidth and the whole thing oscillates with lots of harmonics. Sometimes, the cure for this is to add a few ohms resistor in series with the emitter, or a ferrite bead slipped on emitter or base leg of the transistor.
