That design makes a lot of sense. The selectivity won't be great but in an era with few stations, that was not an issue. Breaking the band into ranges and the tuning with the variable inductance would work well. The long handle on the tuning adjustment was an easy way to allow accurate setting.
I would liked to have watched you tune the radio, both with the variometer and finding a sensitive spot on the crystal. I have always wondered just how tricky it was to tune the old radios.
I’ve been able to get new replacement stator crystals. But the movable crystal is tired. It’s very tedious to find a sensitive spot but once you do I’ll leave it until it loses sensitivity. The station selector tuner is very easy to. Just keep moving until you hear a station. The conditions during the recordings were mid to late winter. Optimal conditions. Maybe I’ll do a recording in the future showing the tuning of the crystal. But I’ll need another person or a camera stand to do so, for the tuning of the crystals for a sensitive spot takes two hands. Thanks for watching 🙏
Hello! I made a crystal radio with a synchronous detector (BF998 with shorted gates). I had a 15 meters of wire (V- antenna). To improve quality factor and for tuning on a station I used a long ferrite rod. There was not any litz wire. But the results was excellent - a sensetivity was very good. The crystal set with two coupled variable inductors had a quite big selectivity in MW band. I think - the mosfet detector can much improves characteristics of this antique radio
Thanks for liking and subscribing. Thanks for sharing the information of your crystal set. I love the old primitive circuitry. It’s fun adjusting and moving the crystal around trying to find a sensitive spot to detect a signal. I’ve also used fixed germanium crystals in this receiver as well. In late winter conditions I’ve received a couple Albany stations 50 miles away using the original detector. Variometers and variocouplers are a blast as well sounds like you’re having fun with them too. Check out my video on variometers and variocouplers from the 1920’s. Thanks for watching 73’s 🙏

Beautiful Radio. On my bucket list to obtain.

Very cool. It’s beauty is in its simplicity.
Thanks for the nice comments and watching subscribing and liking the video. 🙏

What is the length of antenna?
70 feet / 21 meters 😎. Thanks for watching and subscribing 🙏
About 5 meters 😎

really aeriola jr lol i guess they wasn't thinking when they named that radio or they had dirty minds like me

Many years back I did something very like that but I drove the gate from a second tuned circuit. Selectivity was greatly improved.
