The plan did not work out. I also went with this VHF operating asset with the same setup as the last one. Why?
But let's do it gradually. When transmitting from a dimension, power is important. This is ensured by two batteries. One powers the Kenwood TR-751E radio, the other charges the netbook via the inverter. However, the manufacturer states, that it should last fully charged on the internal battery 6 and more hours, but under load it is not even half, so recharging is necessary.
A major change was to be the use of a power plant. Tuson ELC1000 seemed to be suitable - it is based on a 4-stroke engine and contains an AVR. At home, I just poured oil and gasoline and tried to start. She caught for the first time.
On arrival at the elevation above the village of Horná Súča, I first built a mast with an antenna. The generator came last in line. She also started for the first time. I connected the power supply and charger of the netbook. Until the beginning of the VHF operating asset remained about 20 minutes. After a while, however, it remained silent. Blackout. The generator turned off. I looked to see if I saw any problem, he waited a moment. She also started right away. However, the blackout was repeated for another ten minutes. I already knew that, that is bad. So I rewired the battery power. What is the cause, that the generator switches off? I do not know yet, but I also have too little consumption. Namely, the netbook and TCVR on reception have relatively low power consumption and may be, that the engine is "choked" when it goes out. Probably also for AVR would be appropriate preload the generator as described by Stano OM8ST
Apparently, the warm weather also caused better conditions for the spread to the south than a month ago. The multi-station signal was stronger than then, at 9A1N I probably also noticed airplane scatter. But it could not be verified, because the netbook does not have such performance, to handle more demanding programs like AirScout in parallel with the logo and KST chat.
KST chat is quite a significant help. VHF is the same, that if the antennas are rotated correctly, thus, the chance of a connection increases significantly compared to the situation when each station points the antennas elsewhere. For example, I managed to connect to YO5LD from KN5 in this way, OK1DOY from JN69 or OK1TDO from JO70. I use wtKST, which suits me more than a classic chat in a browser window.
Thanks to this and better distribution conditions on VHF operating assets in June shifted the number of multipliers to 18 and there is also more to the connection log than before. Quite a few connections were made on call. The map also shows a smaller number of stations near OK2 stations. Damage, that it was not possible to find someone from the Slovak KN squares again, although Slavo OM0AS and others were on the band. Maybe next time.
we'll see, with which he manages to lose a month. Reserves are still considerable, so there is still work to be done. See on the following map, that there are no stations from the Czech capital and its surroundings in the logo. The direction in the line Hradec Králové and Liberec is also very poor.
Log z contestu je už nahraný do Clublog-u a taktiež na https://www.hamradio.hr/vhfrobot/index.php . I, that this should be the standard for any radio amateur to publish a diary publicly, what do you say?
