General discussion forum for antenna analyzers. More Links to AIM4170 Info. Very interesting links by Ian, G3NRW. Good tutorial on the basic principles of network analyzers. Antenna Modeling (by AC6LA). An excellent resource on antenna modeling software. Be sure to checkout the program called Transmission Line Details. Good information on the variation of transmission line parameters versus frequency. Comparison chart for three models of the AIM. The AIM compared with several other antenna analyzers.

Refurbishing a pair of JBL L150A loudspeakers. A business in London specialising in repairs to driver units. They obtained replacement cone surround kits and restored much of the original sound quality. But also I'd noticed that the mid-range and tweeter 'level controls' were rather scratchy, so I thought I'd replace the potentiometers. But to do that, I'd really need the circuit diagram. Then I thought - well, if I've opened the box, why not convert the divider network to 'tri-wired'? Which allowed me a...
