Not entirely on subject since this is for a transceiver, but figured
this would be the group most likely to generate a useful answer.
I happen to like the older Icom IC-271H and 471H, I have a pair of each
where one is currently the control and one is the in-progress unit.
All the normal stuff
these in the lab though.
And yes to get the longest run time, just power the main unit from the
battery as Bob suggested.
Now I am just waiting on some DB-9 connectors. I ran out of them and the
local RatShak went TU.

Might want to dial that back a bit.
Since 12V/7ah batteries are mentioned I am assuming standard small
gelcell units.
Proper float voltage for a deep cycle is lower than a SLI type, and
gellcell even lower.
Generally 13.6 - 13.8 would be the gellcell range, with 13.6 being right
on for long
YES!
Currently working my way through 3 salvaged 5370Bs. :)

I happen to have a less than ideal ham shack/lab and antenna setup.
The shack/lab is second floor in the rear.
The main antenna is an inverted L 30ft straight back from the shack.
There are about 50 pounds of type 31 ferrite in the house suppressing
_everything_ to the point that I cannot
If using silicone oil or grease you do need to keep the water glass
issue in mind.
If exposed to chlorine or phosphorus in can convert to straight silicon
leaving a glass coating.
Silicon oil containing contact cleaners used in a marine environment can
be an issue.

Ahem!
Ethernet over powerline!
NOT PoE!
The various forms of ether over power are (for practical purposes) a
wireless ethernet protocol coupled into the AC wiring.
And yes, it is noisy timing wise, for all the same reason that a

There are 2 different things here.
Setting the time based on a single query.
Disciplining the local clock
Many of the built in NTP clients just Set the time every X
Setting one of these to SET the local clock every X seconds is a less

If you timing needs are loose, let
That is his point.
Initial time comes from MB clock.
System (OS) time is set from that at boot.
During NTP startup for a client it is normal to do a ntpdate to hard
set the OS clock (direct one time set).
From there ntpd would track and adjust.
HOWEVER, there are limits to how much ntpd will
Assuming it does not snow again, should finish the cabling to the new

Picked up a 5335A, works, but not in as good a shape as I hoped.
HPIB interface board and bracket have been removed, along with both
cables running to the HPIB connector board.
The gate time control is intermittent.
Minor, but the screen panel is cracked and the little plastic tabs damaged.
Agreed, I picked up a new in box Symmetricom 58532 this winter.
I was very surprised to get a usable signal from indoors (through attic,

I have a 5370B with a -60111, and a 5335 with a dead 10544.
I also have a 10811D sitting on the desk.
I have been through the 10811A/B manual, and what looks like an
extension for the D/E and various -XXX versions.
It looks to me like the D is a drop in replacement for the A, but did
