Tower mast question
by Stargate 18 Jul '07

18 Jul '07

Howdy all, I am preparing to set up a satellite station with M2 2MCP22 and 436CP42UG antenna's. The wind loads are... 2MCP22 2.5 sq. ft. 436CP42UG 2.0 sq. ft. I have a Glen Martin RT-424 (with thrust bearing), 4.5' tall roof tower that is rated for 6 sq. ft. of load at 87mph. I will be mounting it on my deck as opposed to the roof. (My climbing days are over:-) My deck is approximately 12' off the ground on 6x6 posts and VERY sturdy. I will be using a Yaesu G-5500 rotor in a split configuration with the AZ rotor inside the tower and the EL rotor at the top of the mast. I also will be using a 8' fiberglass cross boom to mount the antenna's on. Now that all of the prerequisite specifications are listed, here is my question.... What should I use for a mast? It will have to be fairly long (15-20') since the turning radius for the antenna's are around 10' and I am worried about it being so long that it will bend or provide a fulcrum to damage the tower. I would appreciate any suggestions. I live in a 75mph wind zone. Thanks, RoD KD0XX A good friend will come and bail you out of jail, A TRUE friend will be sitting next to you saying..... "DAMN THAT WAS FUN"

Has all hope been given up on this one all together? If it could pull one of them AO-7 tricks still within my life time would be a real kicker.

Strange noise on AO-51 again
by OZ1MY 18 Jul '07

18 Jul '07

Hi all, On two passes this evening I and others heard the "strange" noise on the AO-51 transponder, when AO-51 was far to the North. It was the same on the fifth of July. Most probably it is someone trying DSTAR on the satellite. AO-51 is not made for that and has not been opened to DSTAR transmissions as far as I know. If you want to use DSTAR on satellites use AO-27 where the control stations say it is OK. The problem is that you are blocking the normal use of the transponder. 73 OZ1MY Ib

This weekend
by Chris Bloy 18 Jul '07

18 Jul '07

Hi All, First of all, thanks you to all the members that sent me private and via list messages of support! Unfortunately I will be unable to attend the event on Saturday due various reasons and me not acting quickly enough on booking a place :( Anyway, I will hopefully become a full member of amsat-uk shortly and maybe if any of you are visiting Portsmouth to Bournemouth you could give me a demo! A bit cheeky I know, but I am so willing to learn and perhaps teach our local radio club too.. All the best and may thanks again to you all. Chris, M0DQO

New VHF amplifier
by Patrick McGrane 17 Jul '07

17 Jul '07

Greetings from Patrick N2OEQ I just wanted to state.... BRAVO! on the new 87 percent efficient VHF amplifier design. Now maybe something similar could happen with converting solar panel power into amplifier output. If amsat remains with Batteries on Eagle, perhaps they could add one or two extra sets of batteries for redundancy and extended satellite life. Otherwise I would like to see batteries a thing of the past. I wonder what the efficiency of batteries are anyway. I'm still waiting for an update on the new ECHO power software. Did it work or was it abandond? Thanks for the forum, 73, pat
