Re: [time-nuts] FRS-C TTL / sine outboard filter question

Hi Leigh, I can't comment on the crystal filter option., but I've found that the packaged filters and filter/balun modules from old 10Mb/s Ethernet cards work well. See this excellent little page by Dave G4HUP http://g4hup.com/DA/Filters%20Transformers%20and%20DC%20Converters.pdf   Robert G8RPI.

What load do you have it running into? It maybe that you need to load it into 50 ohms. Steve On 23 June 2010 16:54, Leigh L. Klotz, Jr WA5ZNU wrote: > At the local flea market, I picked up what appears to be an Efratom FRS-C. >  It is marked "TTL" internally.  It has the passive connector board,

Leigh, I have the same FRS-C TTL unit. I do not have a manual. Would you be so kind as to send the conversation info to me? Thanks, Dave W6TE - Original Message - From: Leigh L. Klotz, Jr WA5ZNU To: time nuts Sent: Tuesday, J

[time-nuts] FRS-C TTL / sine outboard filter question

At the local flea market, I picked up what appears to be an Efratom FRS-C. It is marked "TTL" internally. It has the passive connector board, but not the active board with the 15 MHz synthesizer on it. Mine is marked "TTL" internally. The service manual has a chart showing the differences b

Re: [time-nuts] crystal oscillators & TPLL

Steve, It is admirable that you stick up for Warren. Part of Warren's problem is his disrespect for some of the other commenters of his work. The name calling and put downs just does not endear him to anyone. Saying to someone that they made a dumb mistake, and if they can't see the obvious t

Poul-Henning posted Yes, you probably did. (Think it was obvious) TRUE, it is obvious to me, but then I've had the advantage of being able to test the TPLL to find the answers to things that I did not understand at first. So is there some part that is not obvious to you? Maybe someone from

Re: [time-nuts] crystal oscillators & TPLL

Thanks Don For all the nuts that want the analysis with math and fancy papers on how (or why) the TPLL works. They will find the whole thing on one line on page 4-21 of that paper. (page 110) That's about it and all that is needed, if one also understands how to do integration by oversampling
