My Week in Radio
- I saw Ron’s photos from Sussex County Ham Fest
- I only go looking for connectors and gadgets, not real gear.
- Enjoyed Luke’s talk at breakfast
- cat whisker and spark gap
- reminds me of the books I read as an elementary student
- crystal radios
- want to build one again and see about tuning it for medium and shortwave
- POTA: Caledonia
- used the 12.5M EFRW instead of EFHW
- afternoon, 40m was dead
- 20m and 15m was very busy with SSB contesters
- 15, 17, 20: all EU, and very little local,
via FT8 and SSB, but they couldn’t hear me.
- atmospheric diode?
- only made 4 contacts in the hour I tried
- Tape Measure YAGI is amazing for hearing the workbench
- I didn’t want to need to pick a direction, but seems OK for these longer sessions
- Purchased an inexpensive variac
- so now I need an old radio with some questionable capacitors. :)
- I’ll be at the breakfast, then finding a park to activate afterward.
- Writing a bit for the blog in down times

Question
- Perseids meteor storm coming this month,
What’s involved in working meteor scatter?
- Widen topic to: Any special propagation modes?
- Jim: e-skip?
- Row, WA3VEE:
- Tropospheric ducting
- temperature inversion
- listen to FM broadcast in the morning
- difficult to hear local
- hearing much longer distances
- it’s a mess of overlap
- means there’s an opening in 2m
- dxinfocentre.com for tropo forecasts
- Meteor showers
- listen to 6m.

- Chuck, NA3CW
- Signal around the world
- 1-2 second delay to hear your own “hello”
- Japan at 10w
- 1-way propagation
- atmosphere is turbulent
- photons strike into ionized air molecules and electrons
- the wave jiggles the electrons in the air, and they retransmit
- this “reflection”
- signals going the other direction may hit different conditions along the way.
- Signal around the world
- KC3WWC: antenna orientation?
- W1RC, Mike:
- Digital modes for studying propagation, since it can be monitored
- WA3VEE, Ron
- EM energy is released when an electron drops into a lower orbital
