We bought one of these from Mike a couple of years ago, and it has worked
flawlessly ever since ! Terrific antenna splitter ...Never complains, goes on
strike, wants a raise ! or spends too much time at the water cooler !
Thank You

Mike, are able to ship to Canada and do you know roughly what the shipping
would
be ?
I would be happy to purchase 2 of them so long as the shipping is
reasonable.
I can pay via paypal or send a bank draft in USD.
Many thanks

Hi all,
I just picked up an irresistibly cheap 5370A (so cheap I didn't ask if it
worked).
So far it checks out ok, but I have some questions for those of you more
familiar with this model.
1) The back panel heatsink (4x TO3) is sitting on 76°C (168°F).
- is this normal?
2) Several resistors
Yup various components have been run hot.
Like others in this group add a fan to the heat sink. Found a way to route a
wire out from the raw 5 volt supply to run a 12 volt fan. Think I took one
bolt out of the heat sink to route the wire. Think I added a resistor as I
did not need a lot of air to
My 5370a's both run hot as heck. I used some cheap small c-clamps and some
old heatsinks to increase the area of the hp heatsinks. You can also run
an old fan if you have one. I've found that the whole era of Hp equipment
runs too darn hot. 3325a, 8656a, etc. etc.

Hi all,
I just
Hi
Gee, a low cost 5370
The nice thing is that even though it runs hot - it's done it for a *long*
time. I certainly would not argue against a fan. They are a *very* good
idea. However it's not going to turn to dust without one.
I would definitely keep it clean and keep the back side open
Hi All
I've recently had the opportunity to scan the manuals for the Trimble
SveeSix GPS receiver and for the Acutime 6 Channel GPS Smart Antenna, which I
suspect might be the earliest Acutime unit, and would like to say a public

Hi Mark -
I have shipped a lot of these to Canada. The shipping cost is the same for
one or two units, and it is $11.95. If you pay by PayPal please add 4.5% on
to the total for their fees. PayPal to n...@eozinc.com . Thanks 73 - Mike

I think 61°C might be more typical, so 76°C seems pretty darn hot to me. I
would make sure that your fan is running, and is mounted the right
direction. (It should be blowing *into* the instrument.)
Also make sure that the top instrument cover is installed. (The top cover
must be in place so
Consider the following scenario. We have a signal source of about 10 kHz,
with unknown phase noise. Let's for simplicity's sake assume for now that
the phase noise is large enough that it will be detectable by the following
approach.
We measure every zero crossing with lets say 1 ns accuracy.
Forgot to mention that in this example we are only counting the zero crossings
on the positive edge.
(before some clever soul points out that it should be 20,000 zero crossings. :P
