Peter,
My UT+ works ok with common antennas, I tested it with a Trimble
28367-00 and with a INPAQ AAF-03B 5V. Both are quite old garden
variety GPS antennas intended for car navigators so your problem can be
in the receiver.
I bought mine from fluke.l and he still have some available on his
Fellow time-nuts,
I have now diagnosed the unit B A15 PSU board to such a level that I now
know that the 9100-2478 transformer in the +20V to -20V switcher.
If someone is sitting on a spare transformer or A15 board (with working
transformer) that I could buy from you, please let me know. The

I may have that part in stock somewhere. Years ago I parted out the
un-needed guts of the 5065A I'm now using to transplant a Z3801A. I
likely would have saved the major parts from the boards, stripped en
masse on my solder machine. If you or anyone happens to have a good
picture of it, please
Hi Peter, yes it sounds like the UT+ is defective if it never gets any sats.
You can probably find one on eBay. Someone probably fired RF into the receiver
front-end and zapped it. I think the antenna you are using should be OK.
I will look for my drawings on this unit and send copies to

Hello,
I am looking for a PCI-GPIB card to use in a machine running windows XP.
After looking on Ebay there are many different options at many different
prices.
I am not sure which would be compatible with my set up.
Currently I have a ACER Laptop, with a NI PCMCIA GPIB card and I was able

There was an PCI-GPIB from NI offered on TestEquipTrader on Yahoo a couple

Hi, K4CLE
A while ago, I invested $600 in two pairs of the GPSDO and LPRO units.
Intended to replace a pair of 48 volt Z3801 receivers with 24 volt units.
Put them in the project pile for lack of drawings and software, where
they have languished. Their value has dropped, but I'd still like to

The quick and cheap migration to a desktop PC if you have the PCMCIA GPIB
card is to get a PCI to PCMCIA adapter. They are cheap and plentiful for as
little at $6.50. e.g.

USB can be a pain if you have several, how do you ensure they pop up
with the same identity? Serial port adapters have that issue. Not aware
that there is a general solution to it. For USB at least there is a scan
order to assist, and USB doesn't hurt as the ISA did.
Cheers,

But if they are USB HID (Human I/F Devices) There is no drive association.
I have no HID expertise.
On Linux, the udev stuff helps with that.
FTDI serial-USB adapters have a serial number. That lets you can associate a
name like /dev/gpib with /dev/ttyUSBx where the x is whatever the
You can troll sci.engineering.design for users of the prologix usb and ethernet
interfaces. However I think the best suggestion was to get the pci to pcmcia
adadpter.
My recollection is cardbus is 32bits and pcmcia is 16bits. My it shouldn't be
an issue unless you try to run DOS. The only
The PCI and USB HPib interfaces I've seen are terribly expensive.
Wpuld it be possible to fake an interface with a parallel port and bit
banging?
Possibly an Arduino?

Sure... but surplus NI cards turn up pretty cheap, and the Prologix

NI used to have a trade-in policy. You would get half off the new price.
The trade-in page was always kind of hidden.
I took a quick look, but don't see it on the website. It wouldn't hurt
to ask NI, since they know Prologix sells for half their cost.
There are scans of the L-Pro service manual out there. Google should help here.
