This list of projects will grow as I
get around to doing the documentation for them. Some will be just circuits but I
will attempt to put some words to them as time prevails.
APRS...
25Watt PA for APRS (PDF Download). This uses a 2SC1946 and is intended for boosting a Maxon Data Radio to 25 Watts. For more Maxon info - please see http://www.qsl.net/zl1vk . Harry ZL1BK, Keith ZL1BQE and myself ZL1SWW ran demonstrations of what could be done with them at Branch 65 and 66.
Tinytrak and GPS integrated in one box -- This is a Tiny Track and GPS in one unit with common serial port and mutliplexing.

Build a 925MHz 9 El Yagi
Antenna.
1296MHZ
My VK5EME 1296 transverter
pictures, beware, some of these are quite big and may take some
time to load, shows part of my messy hamshack. I will write up a bit of this
when I get time. Check from time to time on the sequencer as well as I will update the info
on that as well with the PWM pump circuit mod.
1296 Transverter
saga
... This one is a "bitsa" - made from many bits and pieces.
2.4GHZ
Progress on the 2.4 GHz
Transverter as it is
being built..
5760MHZ
Bits...
The DXR-700 Unit Conversion Details for 5.7
Gig, an in progress page - keep a
watch on it..
The following
pages may change from time to time, keep a watch on it
also..
Update 1 - Interim playing around
with 1 PLL driving both converters.
Update 2 - Generation 3 - Most likely the final one and
the best solution so far..
10GHZ Bits...
DXR-700-710 Transverter and mods needed to make it
go..
