Hi Chuck, Serious contesters have directional antennas and most of the new contest quality rigs have FFT spectrum displays and the ability to record several Mhz of spectrum directly to disk for later analysis. The old stereotype of unsophsticated home brewed gear is now a subculture of

Re: [time-nuts] PN sequence generation using GPS

Speaking as a ham, if this is tried you will have hams complaining and DF'ing the offending signal. Chuck, you are correct in that no one but the hams care but the reason behind this is that policing the ham bands has been delegated to the hams and specifically certified 'Official

Re: [time-nuts] 5370B s/n prefixes

Why not just use the output from the 5370B - it already has the support circuitry and a buffered output. Back in my pre-time nut days my 5345 was both counter and lab reference standard the 10.mhz output went to a D/A so all my instruments were referenced to the 10811 in the 5345 Scott Sent

[time-nuts] CS reservoir depletion

Now that we are discussing how to restore Rb lamps. Has anyone given any thought to refilling or refluxing the Cs in depleted Cs tubes? Obviously opening would require high vaccum equipment - which is a totally separate category of nut (Or is it?) Scott Scott Sent from my Verizon Wireless

Re: [time-nuts] Archiving Timing Data

Have you thought of using RRD (Round Robin Database). RRD is a CSV format which stores value vs time and is generally used for archiving network performance data which is generally kept for years. This format has the advantage of compactness and arbitrary x y scaling. MRTG (Multi-Router

Re: [time-nuts] Question on GPS and reference standards

Because the Rockwell-Collins HF80 has sensitivity and selectivity which are avaialble only in Ham gear costing 7000+ definitely not in the 'inexpensive' category, it's transmit signal is also far cleaner than most synthesized HF Rigs. So it makes sense to upgrade the reference oscillator to

Re: [time-nuts] Time Code generator

When audio/video time code is specified if its on a audio track its called LTC or Longitudinal Time Code and is generally IRIG-B, This is very uncommon these days as it went out of common use about the time 1 reel to reel was discontinued. Most common today on NTSC is VITC or vertical

Thanks for update on current LTC usage!. In the studios I worked in in college with the old type-c decks we did use IRIG-B but even then everyone was moving to VITC. As editing was moving away from the razor blade and tape era to deck to deck on U-Matic decks! Scott Sent from my Verizon

Professional cameras have a integrated VITC generator which in addition to the time add the frame index to the time code which allows for creation of frame level Edit Decision Lists. Consumer cameras cheat and synthesize time. If you run a consumer tape through a professional system you will
