Re: [time-nuts] Z3801 question on EFC at 81000 but stable

Jarl Responded back and you have to open the outer oven. I know thats nasty, but there is an adjustment. Not looking forward to that effort. Regards Paul WB8TSL On Sat, Nov 15, 2014 at 5:34 PM, Arthur Dent wrote: > "I also seem to recall pix of the Z3801 oscillator and there were not any > adjus

Re: [time-nuts] strange carrier

I was thinking of a new alternative we may have not considered. Absolutely near field. The solar panels popping up on the roofs then hitting an inverter sync'ed to 60 Hz X 1000 would be a mighty fine transmitter. I know in our area numbers of homes now have them on the roofs. Regards Paul WB8TSL O

"I also seem to recall pix of the Z3801 oscillator and there were not any adjustments. I sure hope I missed something." Thanks Paul WB8TSL + There is an adjustment on the inner 10811 oscillator but it isn't easy to get to. Here is a description. http://www.2917.com/EBAY-images/10811-601

Re: [time-nuts] strange carrier

Hi Ed: The DISEqC protocol is a low level signal at 22 kHz which would not make the signal being discussed. If it was me I wouldn't look to the neighbor until I was sure it was not coming from my house, hence the shut down the house first approach. It's very difficult to generate any signal s

[time-nuts] Strange Carrier

Brook's suggestion to shut off your house power is an excellent one; however, your neighbors could be involved, too. A portable transistor radio tuned to the low end of the band where there is no station would make a good electrical noise detector -- assuming the mystery signal has harmonics, t

Re: [time-nuts] strange carrier

A signal like that coming from a dish makes some sense to me. I vaguely recall from about ten years ago investigating how the satellite receivers work, that a fairly strong control signal of around 20 kHz was used in some to select the various LNBs and their polarizations in more complicated sy

[time-nuts] Z3801 question on EFC at 81000 but stable

OK since I have the z3811 EFC around mid band at 5, now the question comes up on the Z3801 is at 81,000 for the EFC. Its quite stable. But I seem to recall on Time-nuts a while ago that when the EFC gets to 100,000 or 0 it stops working? On a traditional oscillator I know that you could adjust

Re: [time-nuts] Division Circuit

Brooke - You must have meant the 923. The 723 is a voltage regulator. I also used to have fun with the 900 series RTL stuff in the mid 60's. 73 - Mike Mike B. Feher, EOZ Inc. 89 Arnold Blvd. Howell, NJ, 07731 732-886-5960 office 908-902-3831 cell -Original Message- From: time-nuts [mai

Re: [time-nuts] STEL-1173/CM Source

Yes, I'm sure. I did check the cabling. :) If I was somehow measuring the Tbolt or 4065A against itself, there wouldn't be any frequency offset. The Oscilloquartz 3210 (which appears to be an OEM'd 4065A) is spec'ed at 3E-13 @ 100K seconds. The 4065C is even better at 8.5E-14 with a noise f
