QRP Minima

How i meat Minima.

One morning i search for Si570 and Arduino i came to this side http://www.phonestack.com/farhan/minima.html

Thanks Ashhar Farhan, for this transceiver.

Then i was really curious on this project, and start search more information.
The main page for this is http://www.hfsignals.org/index.php/Main_Page.

After a while i came to this side PP2KR.

Then i could not resist to bye the PCB from Kleibe PP2KR, thanks a lot.

Hear are some more god presentation. Thomas KK6AHT.

Here ar more links.

Now i am waiting for components to start build the digital board. Get it up and running, measuring on Si570 compared to AD9851. I will put up result her stay tuned.

QRP - Tuners

This was mad a year ago but not marked. When i was on a QRP event i must take off the cover to understand how to use it, the labeling is now done. The inspire is from this tuner http://www.qrpkits.com/blt_plus.html

Later i came across this on ebay and order one kit. It looks ok, have only tested in lab-bench yet.

Hope it can be more used together with my QRP transceiver KN-Q10B, and the rig from this winter project, hopefully, stay tuned.

New Fox Receiver 80 M

This is a new board i receive a few weeks ago, Most off the resistors is now in place. I hope this will be the best receiver i have. The author is Bosse SM5CJW. I will experiment with the antenna for this receiver and see how it will preform. Compare ferrite -road and loop ant. I will put upp result hear, stay tuned.

Fox Hunting

Long time as i write here. Fox hunting is one of may big interest. In May we run a fox hunting in Lindesberg Sweden. With this Transmitter, 5 pcs 1 with a broken antenna connector, this is now solved and hope to not happen again. Her is some data.

The software in transmitter and PC is made off may son Mattias.

We have no start planing for a 80m version this winter.
