Two things: one: all the station components are in PY soil. Some arrangements were made to bring the best equipment possible.
FT-840, Pyramid ps21, multiband antenna and 20mts of RG-213.
For the next year we need to decide the location.
two: a big TODO is to beat the distance record of data transmission on the 2.4 GHz band (wi-fi)
Long distance wireless access.
A fundamental part of an irradiant element is the impedance matching.
In order to achieve the correct matching impedance between the irradiant and the feed line we need to build a balun.
Of course there are a lot of baluns diagrams out there in the internet. This is an easy one to build. You can use a ferrite rod from an old radio to build your own.
Set up a ham radio station somewhere in Santa Catarina.
First stage: HF bands
The transceiver - Atlas 210x Special Edition. Mic Shure 450. External speaker Dual.
Antenna tuner - MFJ-949c
Find a power supply from a local provider.
Baluns - Try to find if there’s one alive.
Antenna - Depending if I can rescue a balun from the CX leftovers or need to buy. A good one could be to buy a cheap dipole or G5RV from a local dealer. Focus on 40, 20 and 15 mts bands. This could be an option. Electril Antennas
Coaxial and connectors - PL-259 and around 20 mts of coaxial cable from local dealer.
A while ago I had the idea to create a solar water heater. We need to have a tin box (the bigger the better). The box must be painted in black in the inside and isolated with expanded polystyrene or similar. On the inside of the isolated box we need to put a copper coil like the ones used on the back of refrigerators. The more the pipe turns, the more capacity it creates in liters. The water comes in from one side of the pipe through a hole in the box and out from the other side. In order to keep the coil with the water hot, we need to cover it with a glass and position it towards the sun. The glass allows the sun rays to get into the box, heating the water in the pipe and avoiding them to exit.
Since my radio site went down and CX6CAU is QRT for the moment, I felt the need to keep alive in some way my passion for the radio waves and the pleasure of hearing the noise of the static.
I would like to start for the “knobs”. The inside of the shack gear
This is my main HF transceiver is a Yaesu FT-840.. Oh what a beauty!
A simple radio, easy to understand, with an excellent reception and works very well in all bands. I like very much to watch the needle meter and nowadays is not so common to find a needle meter in a compact transceiver.
Amazing AM broadcast reception with the native speaker. The output power is 100 watts.
The VHF rig consist in a transceiver Yaesu FT-2500M. Rugged and solid. Unbreakable. Three levels of power output: 5, 25 and 50 watts. The perfect combination for the vertical 5/8 SR2 from.
