Some time back I needed to purchase some caps to cover RF connectors.
Despite only wanting a couple of hundred of each, I was unable to get
small quantities, so had to buy either 2500 or 5000 of each, so I have
a few to spare. If anyone wants to cover their plugs and sockets to
stop dirt and
I forgot to add. There are some pictures on eBay of these, but I'm
selling them cheaper off of eBay, but you can see the pictures with
the various connectors. (No PL259 or S0239 shown, but they do fit. I
had to hunt hard to find such connectors here)
I hope this is not to far off topic. Does any one know if the 4193A and 4815A
probe are physically interchangeable and electronically compatible? If not does
anyone know the differences and how to identify which is which? If you feel
this is to far off topic please contact me directly. Thanks
The 4815A used P channel FETs which were available 50 years ago
and are now unobtainium.
The 4193A used N channel FETs which were available 10 to 30 years
ago and may even be currently available.
They are DEFINITELY NOT INTERCHANGEABLE.
This is according to ex-HP'er George Standford, who used
Hi Rick, Tom,
one little bit of knowledge I learned: I like the HP 54701A FET probes for
frequency-domain stuff.
Available for $300 on Ebay sometimes. I built a small power supply for one
of mine, and use it as a probe for my Spectrum analyzer and scopes. Almost
indestructable.

Thanks Rick; There is so much conflicting information I do not know what to
believe anymore. George sounds like the person to talk to. It sounds like an
aftermarket probe would be a great way for someone to make a few extra dollars.
I like the Tomco option, it looks like a nice instrument.
I agree the 54701A is really a great product. Great point on attenuation, I
always forget the 10x attn value changes when not being used on a O-Scope as a
voltage probe.
Thanks;
Thomas Knox

Hi,
What NTP REFCLOCK can be used for a Jackson Fury?
I know that the Jackson Fury docs suggest using:

You can use FreeBSD. I will dig out the refclock I am using with my

One normally uses the ATOM driver with PPS. If you need to number
your seconds I've heard of a SCPI (hpgps) driver but I suggest using
another one of your clocks or any

Sorry, hpgps is the driver/port name but the NTP driver id is GPS_HP.
Again, I have no direct experience with it.

With my Z3801A (which I understand the Fury to be compatible with at SCPI
level), I use GPS_HP refclock in ntpd, along with nanokernel PPS. I had to
tweak baud rate in the source code.

I think I used type 20 and 22 with bsd on my soekris. I have had it off for
some time because it started to error on boot. Have it apart now trying to
figure out what is going on. I suspect a problem with the clock block.
Set the fury to output ggtts.

Did you mean GPGGA?
If the Fury is producing RMC sentences then NMEA+PPS (20+22) should work.
Some folks recommend the NMEA PPS option (flag1) but in my experience it's
less stable than the

I've been searching for the small copper hardline I can use for the feed on the
gps volute (egg beater) antenna. Can anyone steer me where to get a foot or so
of the small 50 ohm line so I can make a few antennas? I've been searching
mouser to no avail.

0.250 is another size UT makes.
Might try ebay.

If you know the RG designation for the specific size you are looking for,
search for that.
Mouser and Digikey don't carry. And the people that do will have minimum
