Fox Transmitter

10 May, 2012 (07:29) | Arduino, FOX Transmitter | By: admin

Some new images from my FOX-Hunt transmitter project. The hardware is almost finished. Just a small accident when the magic smoke that all electronics is running from left the transmitter circuit. But i think it’s a rather easy fix. The software still has a few bugs to be fixed, i have a real hard time [...]

Rävjaktssändare

1 May, 2012 (20:25) | Arduino, FOX Transmitter | By: admin

Satte ihop en liten kort film under pågående bygge av logiken till en rävjaktssändare. Nu är det inte rävar som skall jagas om någon tror det, utan det är sändaren som skall jagas med hjälp av pejlutrustning. Har en bit kvar innan den är färdig, känner mig väldigt rostig när det gäller att programera, så [...]

MKARS80 update

A small update on the MKARS80 tranciever. The box is finished and now it just the final alignment left.

Solder Holder

29 November, 2009 (15:00) | Electronics | By: SE3K

I had some problem with where to put the solder when i was building. So i built a small holder. It works very well, the ony problem i have is that my daughter find it very fun to pull out the solder.

MKARS80 Smoketest

19 October, 2009 (10:44) | Electronics, MKARS80 | By: SE3K

Here is a small clip of me running the smoke test of the MKARS80.  After this test i connected the display and processor and it worked fine to. Next up i think is the hardest part, to drill holes in the box, and hopefully make it look good to. There is also some final adjustments [...]

MKARS80 update

All toroids and all capacitors is in place. Now it´s time for semiconductors and crystals.

MKARS80 update

14 October, 2009 (23:49) | Electronics, MKARS80 | By: SE3K

Not much new this time, but at least 4 toroids are mounted at the board. I don´t like the #38 SWG copper wire, it’s like winding hair

MKARS 80 update

9 October, 2009 (14:17) | Electronics, MKARS80 | By: SE3K

The latest update for the MKARS80 tranciever. I have now soldered almost all capacitors, and the next stage in the building is to wind the coils, about ten of them. Just one resistor wast misplaced. I had placed the 56Ohm resistor that should be in the R1 position in position R56. It was no problem [...]

MKARS80

6 October, 2009 (22:58) | Electronics, MKARS80 | By: SE3K

A while ago i ordered a 80m SSB transceiver kit called MKARS80 from www.radio-kits.co.uk and now i have started the building of it. The kit is really nice packed with a easy to read manual. I’m posting pictures and info here about the continuous work. Today i have unpacked and soldered some resistors.
