Hello QRPers, now a better translation (TNX Mike).

Miss Mosquito - small but remarkable.
The newest project of the German QRP club (DL-QRP-AG).

For some weeks we have had an idea. The minimal radio experiments like the
Pixie, FOXX, RockMite, etc. encouraged us to also experiment in this area.
We were crazy enough to set the mark higher and put a transceiver in an
Altoids case without the limits other rigs have had. Until now.

- Superhet instead of a DC
- VFO instead of a crystal
- adjustable RX
- PA with 1-3 watts

Three different designs arose during our discussions, but our chief
designer/constructor, Peter  DK1HE, won out in the end. The name of our new
baby is Miss Mosquito, because, while she is small and fragile, she is also
wild! A mosquito definitely capable of breaking through a pile-up.

Here are some pictures with the prototype.

The complete Mosquito. If you look closely, you can see the crystal filter
for the RX.

And now from an other viewpoint.

The whole rig.

Of course, there is a schematic. Without a schematic, one can't build a
prototype. You can download the schematic from

http://www.werdau.net/qrpproject/manuals/schematicMoskitaVer3.pdf

At this time we have built two other 40m Mosquitoes. At the next open club
meeting, we will present the Mosquito to anyone interested. The Mosquito
should revolutionize the price arena for monoband kits. These kits are the
ideal rigs for a group with an Elmer, and such rig building in a group
should help reactivate home brewing in your area. If you are are a licensed
amateur, you can build now something special for your station. If you don't
have an amateur radio license, you can build the kit as a superb 40m RX
(just leave the PA transistors out).

We cannot guarantee any concrete ready date at this time, but the kit
should be ready for HAM-Radio 2003. The price should be around 55 Euros. An
optional kit with an Altoids case, jacks, variable resistors, and other
parts will also be available for an additional 12.50 Euros.

Advance orders are being taken at this time, and questions about the
Mosquito should be via email to [email protected]
