Various radio-related designs, including yet another PIC frequency counter and VFO. The SWR/power meter is pretty cute.

RM 96 Transreceiver edit / delete

Nice simple 7MHz design from India -- which has the advantage that it's mostly easy-to-get parts. The VFO in particular looks useful.

The SI570-based VFO is particularly interesting.

Radio projects from Brazil. There's a good page on building a Colpitts VFO, among lots of other stuff.

Ham radio projects, including instructions on how to wind coils, a wide range of low-power FM transmitters, and several receivers based on recycled VCR tuner modules. Suitably entertaining in a Swedish sort of way (note the "Wife Replacer" project).

G3XBM QRP (G3XBM) edit / delete

QRP homebrewing from one of the designers of the Pye Pocketfone. Neat stuff, although not immediately that useful to me.

CARC Newsletter: The PA0RDT Active Antenna edit / delete

Neat "sampling" antenna for lower frequencies that uses a length of circuit board as a whip with a simple amplifier connected directly to it.
