I have an Oncore UT+ for a project and found that it works fine after
updating the almanac and getting a 3D fix but it never stores my location
coordinates in its EEPROM. Each time I power up it shows all zeroes in Lat,
Lon, Alt for about an hour or so until it finds satellites. With Lady

For those interested, Dave PA5DOF and your's truly are working to get the
doubler implemented that Luciano has on his website. The first PCB prototype is
in and has been built and works OK. Some minor tweaks/fixes will be added to a
V0.2 PCB. If there is interest I can share the Gerber files.
Hi
All these devices *can* be sensitive to the environment. What degree of
sensitivity they have is a function of how “nutty” one went on this or that
design. It also is a function of things like cost, size, and power consumption.
The target market for things like the 5071 is a “we can afford i

Hi
The PLL will have the same 20 log N issue plus a number of other
problems. The big question is: what are you after?
If you need something below -175 dbc / Hz far removed, what is
the application? There may well be better ways to do this or that.
If you are after -125 dbc / Hz at 1 Hz, tha

Always fun to take a look and some very attractive starting bids. But then
as time goes by it will get crazy as always. Then $400 or so in shipping
and heavens knows what customes will be. Oh well nice to look.
Thanks

Prima
I see you are using two for the phase noise test setup (a common way of
doing it). I am curious about the phase matching between units. From the
results it appears they must be pretty well matched, but did not see any
actual data. Since it is over a very narrow frequency BW it should be no
problem.
