Actually, it might have. If the antennas were like stacked dipoles, one over the other would put each in the others dead zone. Moving out 100' means they see each other much better. -- Dave Gomberg, San Francisco NE5EE gomberg1 at wcf dot com All addresses, phones, etc. at http://www.wcf.com/ham/info.html -
RE: [Repeater-Builder] Simple Emergency Repeater Idea
I ran a 6m and 70cm multicast repeater for years with 100' horizontal separation and 30' vertical separation. Granted the vertical separation makes more difference but the 100' horizontal certainly didn't hurt. I ran 100 watts on 6m 1.7meg split and about 55 watts on 70cm. I did finally get 2 small cans on the rx side of 70cm but the gains were small. As of today, I'm starting it all over again at a new location. This time with full sets of cans on new machines. =] Chris Kb0wlf. -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Dave Gomberg Sent: Saturday, February 14, 2009 6:11 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Simple Emergency Repeater Idea At 01:19 2/13/2009, paulamywood wrote: >I am not sure if this would work. > >You have 2 handhelds with remote PTT jacks on it. > >Set Radio 1 to the Input freq >Set Radio 2 to the Output Freq > >Take the audio from Radio 1 out jack for the external earpiece and put >it to the small jack on the output freq. This might work on 70cm if you vertically separated the antenna by lifting one of the HTs on a piece of monofilament thrown over a tree branch WAY up in the air. Might be worth trying if you can get the upper radio up 100 feet or so above the other.

[Repeater-Builder] Simple Emergency Repeater Idea
I am not sure if this would work. You have 2 handhelds with remote PTT jacks on it. Set Radio 1 to the Input freq Set Radio 2 to the Output Freq Take the audio from Radio 1 out jack for the external earpiece and put it to the small jack on the output freq. In theory it should key the out put radio to rebroadcast the signal. my MP3 player has a record feature that will allow you to go from the head phone size jack to the smaller jack. I am going to have to try it when I have some time, but any thoughts on this?
