¡SSB en fuego!

This past weekend was the CQ WW SSB contest — one of the big ones. I usually have a vague idea about the approach of a contest and decide whether to take part on Friday of the contest weekend, but I had marked this one on the calendar ahead of time and was prepared. Aside from setting up everything and working a bit of SSB earlier in the week, I spent some time looking at propagation and figuring out where to point the antenna at different times of day to hit both areas with high densities of hams (NA, EU, Japan), but also beam heading that would cover the most DXCC entities, the multiplier for this contest.

VHF Update: Repeaters, Earth and Sky

Relais 5R8ZZ

I got an email from Albert, 5R8GV, last week alerting me and other hams in the area that Serge, 5R8GX/FR5GX, had put a repeater into operation: 5R8ZZ.  The repeater is based at his house and puts out 16 watts (after filters) through a quarter-wave ground plane antenna on his roof.

No PL tones are used; instead send a brief 1750 Hz tone to open the repeater.

A tale of low power operation in the dark.

For the past couple weeks, we’ve been experiencing load-shedding that starts about an hour after sunset.  The capital region of Madagascar does not have enough electrical power production capacity at present to run everything at once, so there is a rotating blackout. Now that I’ve added some UPSes, this has minimal impact on my family because we have a back-up generator that comes online in under a minute — usually. Last week, the generator didn’t start rumbling and we sat in the dark [presumably] looking at each other.
