Joule thief

28 MHz VXO - PTO

Is very good , KE7HR Paul R. Jorgenson -five crystal ,VXO . VXO my work on 28,2 MHZ

24 MHz VXO - PTO

Ring turbine

CD wind turbines

CD wind turbine with "joule thief"

CD wind turbine with "joule thief",when the wind blows, at night, lights up well

28- 28,080 MHz RX

Floppy vertical axis CD wind turbine

Voltage multiplied by 4

Generator 3w 6v

Bicycle generator "Union" 3w 6v . Voltage multiplied by 4 times

"Heavy" gigahertzs

Tried catch the internet - no luck. Will do solar collector. If it fails too - I'll make a table from it hihi

Simple 2,8w linear generator

700 turns 0,2mm , coil 2,5cm x 1,5 x 1cm ,neodymium shiver, multiplier,the result about 2,8w output. Using wind turbine , can throw int the yard or garde all night for free .

Linear generator 16v

Two 3000 winding coils, wire 0,2mm , 5cm x 5cm x 1cm neodymium magnet. 4v multiplied by four, the result is +16v about 0,7 A.

CD wind turbine with Epson stepper

Epson stepper motor from a broken printer ,capacitors and diodes from an old computer. CD wind turbine turns on very low wind, very quietly, the LED light up brightly in the dark. Green energy cost 0 USD.

24 MHz QRP TX

10m RX

Simple 50,1 MHz converter with LA1185

UB5UG not completed TRX

14,068 MHz receiver

50,060-50,1MHz RX IF 22,118 MHz

28,00 - 28,100 MHz RX IF 22,118 MHz

TDA 7052 28MHz receiver

27 May, with 5meter wire, heard LA3G? SP...

50,06- 50,120 MHz TX

The 50MHz RX "MINIMALIST"

Fits like a tone control transmitter, frequency meter...

50,06 - 50,120 MHz RX

This is my first attempt to draw schematics with gEDA (Linux). Overall I am very satisfied with the results.

28 MHz 1w QRP transmitter

Nice emitter manipulation of the T1. T1-T3 any 150mc transistor. T4 is 1w, or two 2n2222 in parallel. T50-6 rings, perpendicular. If more power needed one can connect NB6M QRP "gallon".

28,096MHz mini beacon

This one can be heard well within 5 meters.

432MHz - 144MHz mini beacon

On 144 MHz it is heard well within 4 meters distance. 432MHz beacon is heard good about 30cm. For easy converters/receivers testing.

Linux Mint

There was a silence in my blog due to migrating my old PC's OS from WindowsXP to Linux Mint.
The main reason for doing that was that my PC became unbearably sluggish - older PCs and modern anti-viruses don't match. It looked like it dedicated itself to antivirus and OS updating/maintaining tasks - not mine. Despite having constant updating OS and anti-virus (one of the industry leaders) I managed to catch some malware... (I do visit only hamradio related sites).

One can easy guess my reaction after that...

So far everything is going smooth - I like how responsive become my old PC and I have all the tools needed for my everyday work (echolink, spectrumlab, kdenlive). I don't miss Windows and seriously considering to abandon Windows in my Toshiba netbook.

432 MHz TX

Used the fundamental harmonic 24MHz quartz.Multiplied by the apperance of 432MHz . TX easily reapyted, uncritical.Coil L2 may not be connected, directly to the antenna coil L1 the signal strenght is. Best to use SMD coponents. Error,T1 emitter 36 pf not 1000pf

432 MHz Slim Jim antenna

Slim Jim antenna is well suited as field indicator . 100micro A device used 1N5711 diodes. Field indicator finished. Maxlog with a standard antenna ,the indicator arrow for fully tilted 5m Diode conecion uncritical.

Maxlog dualbander
