I took delivery of a Symmetricom 5817A with the 05Q DC power option. The 8 port seems to be going a little less than the 4 ports... not sure on the reasoning there... however I picked it up on the usual auction site for ~125.00 shipped. I thought that was reasonable assuming it works. Anyway, I'm not too proud to admit that I'm not familiar with the power connector that apparently comes with the 05Q option. I have a link below to a couple of pictures. Maybe I missed something obvious when poking around on the internet for documentation, but I can't find anything that describes this connector. I assume it is stock? The +DC input pin/wire can be seen just inside the white tube... again, maybe this is obvious to real time-nuts! I'm working on that time-nut thing!

SMC connectors have jacks and plugs, not Jacks and Jills because the contact and housing genders lead to confusion. See the top of the right column of page 3 here: http://www.marubun.co.jp/product/network/base/qgc18e000003bzbd-att/GPS_Active_Splitters.pdf I believe they mean a jack, which should look like this: http://www.amphenolrf.com/media/wysiwyg/SMC_4.jpg Yours appears to have been broken off.

Max, I'm not familiar with that version of it but I do have the -hp- version which was called the 58517A. I'm pretty sure you can find details of that on line. Not that you really need it, just looking at the pictures you can see the schematic since it's all on top. To try to answer your actual question that looks much like a broken off SMB or similar connector. It looks to be easy to convert it back to standard form which uses the power from the number 1 Rx connection to power the antenna if you wanted to do that. I could do a picture of mine if that helps. Dan - ac6ao

Well I was nearly right, it's a broken off SMC connector. I looked inside mine and took a picture. Converting to the standard form would be easy enough. Dan

That is supposed to be an SMB connector, that is what I have on mine. You can drop in a 0-ohm so that you can feed it and the antenna from Port 1. It might be a quicker solution for you.

Honestly, that looks broken to me. And, it looks more like a broken SMA

I would say your best bet is to open the thing up and replace the

Happy tweaking.

Honestly, that looks broken to me. And, it looks more like a broken SMA jack (at least from the photos). I would say your best bet is to open the thing up and replace the connector with something a bit more workable. Happy tweaking. On 09-May-15 05:58, Oz-in-DFW wrote: > On 5/8/2015 9:11 PM, M.

It needs an RF choke added, the 180 Ohm R removed and four bypass caps added to the empty positions where the 180 Ohm is. Dan

Thanks for all the replies everyone, very helpful as usual. the links that Oz posted seem to match up with the connector on my 5817a. http://www.amphenolrf.com/media/wysiwyg/SMC_4.jpg Its the male side of a SMC connector. I'll remove the broken one from the unit... take a few more pictures. All the comments on bypassing the power input option were very helpful too. i.e. the 05Q option. I figured that should be pretty easy where they sold this unit without the external power option. Again, thanks for the detailed responses gents!

I added a couple more pictures of the connector after removing it from the housing.... I tired to get a better close up on the connector, but it's kind of blurry. After more research, it's an SMC F, female actually... I guess. I assumed male because of the pin inside the plastic / dielectric. http://www.nc7j.com/downloads/NG7M/Time-Nuts/5817A-05Q/ Anyway, I found some good pictures of a possible replacement on flea/Bay/eBay: http://www.ebay.com/itm/Lot-of-2-ITT-050-045-0000-220-Conn-SMC-F-12-4GHz-50Ohm-Solder-Pot-ST-Pnl-Mnt-NEW-/271840415566?pt=LH_DefaultDomain_0&hash=item3f4af38f4e Look at the 4th picture. I'm kind of anal about fixing this kind of stuff, even if I end up going the 0 ohm jumper route and disable the power input to use power from the one of my GPS receivers. Thanks once again... I would have spent a lot more time on my own getting to the bottom of it. 73 de Max NG7M On Sat, May 9, 2015 at 12:25 PM, M.
