It can be done well, and yes, I have done it well. See my much earlier post on the subject. Jim W7RY CETma

Dear group, Any recommendationpower supply regulator board circuit which is tested and proven? I would like to build a pair of 30-40A power supplies for a friend and could use some help Thanks

Dan I have to disagree with you! I have done combining for both UHF and VHF. Is there loss? Yes, is there loss in any duplexer filter system? Yes! If done correctly, do they preform well yes!! It can

Can it be done? Sort of if the frequencies used are ideal. Is it a good idea? NO Will it perform well? NO. It will be a compromise setup at best, likely with a lot of insertion loss, desense, or both.

So, not to be stupid,? my complete keystrokes on my desk pad would be (come off hook, of course)? 01 31 229 230 044 ? If so, I can't believe I missed that crucial step, considering my background.?

This is an informal survey prompted by the recent bandwidth discussion. There are over 5000 members of this list including many highly technical people. Some of you must have done this testing.?

Wow-they want WAAAY too much for those! I can't see going much above $100 for one... And the one on top in the bottom pic is just a cage with some MastrII cards in it. None of those are for the voter.

That seems reasonable enough. I've yet to find a radio (or band) that I could use to run something continuously like that. Seems it would eventually eat PAs. Like trunked control channel repeaters

Em, not completed yet. I'll take one of a 2RU box that is nt a drawer, but has the din rails. Soon. Tom K8TB

Zero hangtime?? Nope..I found ~200-400ms max is needed...mobile chop causes the link to go rapidly off/on etc.. horrible...a SHORT hangtime on links smooths out everything.. or just run the link

Best way to do it is use a regular crossband type configuration at the receiver site. For example, VHF receiver hooked up to a UHF transmitter. Zero hangtime. At the voter site, use a UHF link

Or you could forget temperature compensation and use a crystal heater - way more stable than temp. comp. http://www.masterscommunications.com/products/ch/ch25.html Chuck WB2EDV

Bomar?? Oh hell no....poor quality...I threw anything from them away...

If you have a lot of patience, and a lot of channel elements, I have had good success with just swapping the Xtal into an element that has good stability across the temperature range (~10f to 100f) I
