Alongside your expertise, I enjoy your comments. Even though the media in the US is like on steroids, we here in Europe don't have many AM stations. It depends from country, to country.

[@radioaktiv7841]

So I've heard.. FM seems to be more prevalent in Europe. And I agree, the media in the US is on steroids.

@@radioaktiv7841 In my surrounding Romania has all the bands. Hungary one station, we had one until 2005. Etc. Regarding the media In Europe it is forbidden to advertise pharmaceuticals. And generally commercials are much rarer. We also have private media but it is not at that insane level. And luckily here in Serbia, we have both CNN, VOA and Russian bias tv stations, so you can get informed from many points of view.

Maybe I've gone too far with the concept.

[@SarahRWilson]

I've found that overflowing solder, then wicking the excess can do wonders on that corroded muck. The arrangement of the transistor as a detector, equates to a really fast diode with small PIV, but also small Vf. Thanks Bob Pease!

I thought that one was lost! Great job!

[@barryf5479]

Good job getting it going. At first, with the high resistance measurements on the speaker, I thought the voice coil wires were corroded. You are correct in that there is absolutely nothing worth listening to on AM radio. Unfortunately, the same holds true with TV now.

[@Pawelr98]

10:50 I guess it's a good idea to have a small AM transmitter project as an addon for such radios. In europe AM is not popular, so it's either going for a FM radio or building/getting an AM transmitter. You can have quite a lot of fun building one from those cheap junk tubes (~0.5-1USD each or so), especially if you already have some coils available. Relay an internet station or your own playlist and it's good to go.

If the voltage was to be 4 Volts, perhaps the original battery was a small 2 cell lead-acid battery. The color of the corrosion appears blue-green indicating the presence of copper sulfate. The lithium cell is a good option, as its voltage on full charge is about 4.2 Volts, with a rating of 3.7 Volts, still operating the radio. I wonder if an electrolytic capacitor replacement would put more life in its sensitivity....?

Frankly for the 250 dollars I paid for it, I think I should've bought the blue capacitor esr meter. Norcal715 built his blue esr meter and it seems it's far better at half the cost .

i've done a similar IF bodge in a Hacker RP10 radio, the first IF transformer was physically damaged by a previous ham fisted owner/engineer😉, the original was a double section type, two cores, side by side, but nothing to lose i wired in a common far eastern single core type, orange coloured core, meant for first IF use, and amazingly after a bit of tweaking to match the IF frequency of the remaining others (465khz, i think it was), i'd say it worked as good ,or nearly as good as, new! and i didnt replace any caps 😉 they were ok. this was over 20 years ago, it still works but sounds distorted,(havent powered it up for nearly those years) so maybe now in need of cap testing again 😁 if so, i'll redo the bodge as it was done rather roughly at the time, i'll make a little pcb for it to adapt its pin layout instead of 1 inch long wires it has now

Hmm not so sure about that. According to the schematic shango had on his phone at 22:33 there is a capacitor in that IF can too. And whatever ate away at the wires surely would have eaten away at that cap too. So you would have to at least get rid of it in favor of an external cap. And yes, the chinese schematic is incorrect as their IF can has an internal cap too. That is why shango need not add one externally.
