[Repeater-Builder] OT: Air Band Receiver

Off topic but I know there are some aviation techs on this list. I'm looking for a manual, or at a minimum the alignment instructions, for a General Electric air band VHF AM receiver Model # 4ERC-70-A3. I have one I want to change frequencies on and need the crystal calculation formula and the

[Repeater-Builder] OT: Cell Phone Yagi

I know this is off topic, but I also know there is a wealth of knowledge here. I need to install an outside antenna to ensure continuous cell phone access from my home QTH. The commercial 7-element Yagi is over $100. I know I can make one cheaper than that out of 1/8 dia. aluminum tubing or

[Repeater-Builder] RE: Yagi's For Repeaters?

Thanks to all for the replies on using Yagi's as repeater antennas. All reports seemed favorable so I think I'm going to give one a try. I have a 5-element one all ready to go. Doug VA7DD Yahoo! Groups Links * To visit your group on the web, go to:
