My old laptop was an active matrix, and it still wasn't
readable in sunlight, or even in a room on a sunny day near a window. Rick N6RK "Ian White, G3SEK" wrote in message ...

If the LCD that you remember was an old passive matrix type, you may be pleasantly surprised by a modern active matrix (TFT) display. LCDs are still not as bright as a CRT, though, so I was more than half-serious in suggesting an awning for shade. -- 73 from Ian G3SEK 'In Practice' columnist for RadCom (RSGB) http://www.ifwtech.co.uk/g3sek |

Dear Rick:
I missed your response of some days ago. Now I understand the actual issue. When I feel like it, I have a manually adjustable vacuum variable capacitor that I use to shunt feed a tall tower for 160 meters. The "tap" is such that the real part of the impedance is about 50 ohms and the capacitor cancels the inductive part of the impedance. I use an AEA CIA right at the capacitor to find the right adjustment and then connect the Heliax. In your case, a partner at the base might make small adjustments while you radio back what you wish for him/her to do next. Do let us all know the solution you find. Good luck. 73 Mac N8TT -- J.

An indicator 1000 ft away is useless. Rick N6RK |
