After getting away from a club's heavy 1400 watt generator, I tried using a Vector 600 watt inverter for the Ham IV on the roof of the Rovermobile. Continually blew the control box fuse, till I overfused it then okay thereafter. Square wave inverter problem. Now am installing a Yaesu G1000-DX rotator and not taking any chances blowing it up. Was getting a pure sine wave inverter, costly, now have a generator for half the price and 1 kw normal load. Still have some heavy marine batteries to run the rigs too. For 3 years, never had a working indicator on the control box. Looking forward to the accuracy forthcoming.
Antennas: Aside from the 4 elmt beam on 6, I use full size 18' K1FO's. Here in VE3 I have over 95% of my qso's in an arc E - S - W which reduces the wear on the rotator and on the cables, which are Wireman 106, LMR 400 flex and RG213. Never had a connector fail yet. Need the gain for the longer reach. Large loopers above 432 as well. It must be great for those who have grids workable in a full 360 degrees.
Looking forward to reaching more of you in the future.
73,
