Additional g-5500 mounting question
by Michael Wolthuis 13 Jul '07

13 Jul '07

If anyone has pictures of a "correct" split AZ/EL setup for a g-5500 I would love to see some up close ones. Questions that have been raised: 1) I bought used, but believe I have the seperation kit. It has one piece that screws into the Az rotor to allow the mast pole to go into it and be secured. However, I do not have a similar piece for the El rotor to have screwed into it to sit above the Thrust bearing on the pole. Is there supposed to be two of these? I do have what appear to be a set of clamps, but I can not figure out how to attach it to the pole at the top. 2) What all should be included in the seperation kit, maybe I am missing a part, but can not find a good pic anywhere or a parts list. Thanks, I appreciate the "noob" help! Mike kb8zgl

Mod to disable AGC in FT-847
by Alan P. Biddle 13 Jul '07

13 Jul '07

Hi, A couple of times over the years, there have been requests for a way to disable the AGC in the FT-847 for things like noise measurements. I came across a modification here http://www.frenning.dk/OZ1PIF_HOMEPAGE/FT-847%20AGC-Off%20Mod.htm which is reported to do that. Alan WA4SCA ----------------------------------- It's always nice to have friends. Sometimes, though, it's more honorable to have enemies.

I have a couple of articles already (I haven't started editing yet) but, as always, need more to fill out the issue. All you authors please send me your submissions by July 27th so I can get this issue out closer to on time. Thanks very much to all the fine writers we have in AMSAT that have contributed to the Journal. You really make the Journal what it is. 73, Ed Long WA4SWJ Editor, The AMSAT Journal
