The Olympic flame for 1952 Helsinki Olympics was lit on nearby Pallas mountain with sun rays!

The ski resort has saved thousands of cubic metres of snow for next winter, so they can start early. Also, a big fan! By the way, next sunset is July 18th!

A repeater on the next mountain was accessible, but no reply. DIY end-fed half wave for 20m band works very well!

Received with DIY helix antenna pointing up, bandpass filter, @Nooelec LNA and GPS locked HackRF clone. Signals from GEO sats are weak because from my latitude they are at most 25 degree elevation. Plus heavy "birch-dB attenuation"

Left of this green line is a GEO satellite in an inclined orbit. Very steady sinusoidal pattern. Almost two cycles in two days.

This looks like a inteference, but there is repeating general pattern. At least in 40 hour scale. Maybe an inclined orbit GEO satellite? That double step in the pattern needs more research...

Apparently this is filtering just before the UHF-connector. Interesting detail: red ferrite ring is doing some kind of power measurement? End of RF-autopsy...

Interesting inductor-bridge-thingy (L13, L14) next to this connector! What is that? Looks like it is tapped to ground?

What I understand these are variable capacitors (with plates) and inductors (with caps)

Inside yells analog 80's! Everything's through hole. Only one IC: "LM3900 Quadruple Operational Amplifier". I don't know the manufacturer. Backside of the PCB is quite plain...

It only has this 12-pin plug and UHF connector.

Okay... I'm a newbie to HF communications. One thing what I've learnt past days: When X-ray goes up, bye-bye goes the HF! 😁 But recovery is quite quick...

The bands are slowly opening, but lots of fading! The view is still nice.

Wine, HF and something to read 🙂
