Project the Shack room ; Starting a plan (1)

Happy a new year. It's will late to say that but it's OK.

This month I just a big plan to making a shack room in my house.

I read a presentation from AB1OC in http://stationproject.wordpress.com.

This is a good reference for building a Shack room.

When I draft the room for 3 x 2.2 m. area and paste a tower near room on top floor.

I just design my room on the top because I live in residential and my landscape has a flood in some year.

This position is better. I guess a problem of ground wiring but I find a best solution.

Around my home is clear view and near a river. Expect north view was tall house.

Next we just plan all rig in my station.

3 axis CNC for milling PCB - Part 1

Draft the Rubber Woods for making CNC Machine. This will be using 14 parts for assemble. Rubber woods found in local store. This design can working area in 200x250 mm. Enough for milling PCB.

Now! We will order the woods. Estimate cost for woods is ฿800.

SDR received JT65 on 20m

Sunday I test my homebrew SDR. I get information from YU2LM's Website. Select design single LO Frequency at 140625 kHz generate from Crystal Oscillator. JT65 operating in 140760kHz. This is on range of my SDR. While operate with long wire antenna. I received first QSO between BV7RJ and JA1PLT and signal at -24db. So I think very weak but it good for experiment. It first time.
