The remote controller for the automatic antenna tuner ATU-100 is still under development. The last tests show that the most difficult part – to transfer the display data via bluetooth – is most probably possible as you can see on the video below. But as you can also see there is still lots to doPokračovat ve čtení „So close but still to far“

The third test was to completely test the ATU-100 functionality and that the all buttons control works remotely via Bluetooth. I tried to turn ON/OFF the tuner and then tested the functionality of the TUNE/RESET, AUTO and BYPASS buttons with the corresponding response on the OLED display. The video below shows that the whole functionalityPokračovat ve čtení „The ATU-100 remote controller Part.3“

The second test follows up on the previous testing but adds the function of the TUNE/RESET, AUTO and BYPASS buttons of the automatic antenna tuner ATU-100.Because the tuner uses the negative logic to control the the TUNE/RESET, AUTO and BYPASS function all three LEDs light of the slave module when the tuner is turned ONPokračovat ve čtení „The ATU-100 remote controller Part.2“

The first successful test of the bluetooth remote controller for N7DDC ATU-100. The first test shows just only the test of turning ON/OFF the N7DDC automatic antenna tuner via bluetooth HC-05 modules and using an Arduino UNO as the master controller with POWER, TUNE/RESET, AUTO and BYPASS buttons and an Arduino NANO as the slavePokračovat ve čtení „The ATU-100 remote controller Part.1“

Location: Croatia, Island of Hvar, Ivan Dolac, IOTA: EU-016, Loc: JN83HD.I was allowed to raise my antenna next to our apartment so I moved to the center of Ivan Dolac. Therefore I am able to work directly from our apartment and that’s much more easier. Anyway 20W seems to be bit less then I would need toPokračovat ve čtení „9A/OK1TK/P, IOTA: EU-016“

Location: Croatia, Island of Hvar, Ivan Dolac, IOTA: EU-016, Loc: JN83HD61.My first test of my mobile equipment in Croatia was not quite successful. I underestimated the Croatian soil full of small stones so I was not able to use my plastic threaded pins tu support the Spiderbeam mast. I had to improvise and use myPokračovat ve čtení „9A/OK1TK/P, IOTA: EU-016“

Within the July 2nd till July 8th I worked portable in the small village of Karlov. Karlov is located ca 120 km NE from Prague in the mountains called Jizerske hory where the highest point is 1124 m.a.s.l. Unfortunately my working conditions were not very good due to the high local QRM especially on 20mPokračovat ve čtení „OK1TK/P, LOC: JO70OS“

Today it was my first HF portable operation ca 3,5km from the center of the town Holice. I tested my new Aerial-51 model 404-UL ultralightweight, asymmetrical dipole HF antenna with the 12m high Spiderbeam pole. I used my Xiegu G90 with 20W output power. My sons (OK1RJO) helped me to setup the antenna with hombrewPokračovat ve čtení „OK1TK/P, LOC: JO80AC“
