Receiving some Bangladeshi(?) station. Around 1420 - 1435 kHz. (LO is at 1899 but I forgot my IF frequency, I've changed it again)
I'm located in Europe.
Ran Shazam on one of the songs and it gave me a Bangladeshi singer.
Edit: measured the IF to (469.6 +- 0.3) kHz, by injecting a signal into the mixer and adjusting for lowest beat frequency

A knob came loose and the modulation switch is having contact issues. So let's have a quick look inside this signal generator 👀
I love how simple it is.

Let's have a look at my nas! It's an HP N54L.
There is just one slight problem though. I lost the keys

I've been using it untouched for eons. As a data grave that I only ever power up when I want to access my archives and backups. With all four spinning rust drives running it consumes 40W. With the spindle motors off, this drops to less than 27W.
I broke my little function generator, a Maxcom MX-2020. Used it for sweeping the AM radio and while working on that late at night I accidentally connected it directly to some spicy point in the radio. You want a capacitor in between to block DC voltages, but it fell off the croco cables and I didn't notice. The Maxcom saw about 160V DC at its input. It really didn't like that.
