The problem with the system Google funded is that they do polute spectrum, just not ham radio spectrum (for now). Therefore the studies the ARRL has done which inlcudes going there and driving around show there is no problem. If you think of Google's BPL as the electromagnetic equivalent of toxic waste dumping, the ARRL is more like the AAA (or AA in the U.K.) than Greenpeace. As long as they dump "off road", there is little they can do. It is interesting that in this case, Ed Hare, W1RFI, the ARRL's BPL expert has tried to interest U.S. radio user's groups besides the ARRL and no one was interested in his data. AFIK the only country where anyone has complained about the effect of BPL on commercial traffic was Austrailia. The problem is that the notching out of ham bands is something that can easily be undone. It may even be as simple as the operator of a system entering filter parameters into a control computer. In fact it would have to be, or they could not react to complaints. That means there is nothing to stop a system operator, once they are established >from using the ham bands. > On the ARRL premises Motorola have installed a BPL system that according > to ARRL does not pollute the spectrum . I don't know much about it. I've read claims as such, that there is NO RF polution by the Motorola system, but have seen no hard data. If it does or not, the Google supported system does pollute, they just make sure that no one with an organized voice are the targets of their polution. > So when addressing Google's support for BPL , it seems only sensible to > adopt a more balanced opinion . > Google is an effective search engine ,that's why I use it.

Dick- As I recall, current is conducted via upper and lower springs, to the moving coil. If you can determine that the coil itself is still conducting, you may be able to repair connections to the other components. If the needle cannot be zeroed with the mechanical adjustment, it is possible one of the springs has broken or come loose at one end. It would be handy if you have an Ohmmeter with a beeper, that sounds with very low current conduction. (I've had very few movements with open coils, but have obversed several cases where plating of the pole pieces peeled and jammed the movement.) As far as replacement, look near the bottom of the meter scale. You may find the meter sensitivity listed. It might be something like "FS=1mA" or "FS=50uA". If you determine the sensitivity, any meter with the same size and sensitivity may be useable by swapping meter scales.

Our local university club had one of these that was flakey as well, it had been hit by lightning and both receivers worked, but from the testing I did on it, the ptt no longer worked as ptt, one of the freq change buttons now worked as ptt, but locked on when pressed once, then turned off when pressed again. The other buttons on the mic were similarly mangled up. No one wanted to spend money to actually fix the piece of junk, so it just got shoved in a box and stored away. Good luck on getting yours running, I was not impressed by the recieve audio, and with the transmit problems with the one we had I never did listen to its transmit audio. thanks, John.

Like anything else it requires planning and good layout. Being able to add shielding and all with a good groundplane its hard to miss. Breaking it into modules is a good way to go for a lot of reasons. Expermentation for one and the other being it's easier to test a module and decide if it meets the needs of the system.
