Hello Clint,
Welcome to the group.
For the accurate (stabilized) LO for the 8 GHZ receiver,
consider the new product offering from www.downeastmicrowave.com
They are offering a synthesized LO that uses a 10 MHz external reference.
Also consider thewww.n5ac.com product offering for a

You can probably put one together using eval boards from the mfrs for $500
(1 board for the VCO/PLL, 1 for the loop filter, 1 for the DDS)

Must I hunt and peck through the entire site to find this ?
A little more direction would be helpful.
Tnx, Dick, W1KSZ

Hello all,
I received my TBOLT from TAPR and proceeded to stoke it up.
However I have not been able to get response from TBOLTMON.
I use a laptop with a USB port driving a USB-serial converter marked
N287.
The laptop, unfortunately, runs VISTA. However I can drive an HP Z3815A
with a null modem
Hi Neville,
I just put power to my Tbolt yesterday, so this is fresh in my mind. I'm
running Vista w/SP1 and also running through a USB-RS232 converter. I
wasn't getting a response out of the monitor program until I noticed
that it was set for odd parity. It should be no parity (9600-N-8-1). I
google egm96 and wgs84 to find about the geodetics used in GPS.
there is also an old paper I believe its titled geodesy for the
layman that will get you are started
Your topo map was probably NAVD 1929, a different vertical datum.
