Hi Stefan
Can the 6M be re-programmed the same as the 7M - as described by
Domenico in his post 23 June:
------------------
"in these days, Tony IK1HGI from JN45jj, is transmitting some
(not announced) EbNaut test message on LF and he is active in
op32. He is using a very stable exciter formed by a GPS Neo-7
which time port TP5 has been reprogrammed to output directly the
operating frequency (i.e. 137493,000 Hz).
I invite all interested LF operators to try this solution because
it's cheap, easy to build and it works !
Riccardo IW4DXW, who had this idea, is writing some
post to the group with his indications on buffering the TP5 signal,
obtain a BPSK and ASK modulator, reprogramming the GPS parameters."
--------------------
Looking forward to reading Riccardo's post on how to do this!!

Hi all,
The cheap ublox GPS modules are used by many LF amateurs as a 1
PPS
reference signal source. I see there are NEO-7M modules available
at
amazon, relatively cheap.
Is there any improvement of the Neo-7M over the Neo-6M? I had a
look on
the data sheets but can't find improvements on the stability or
sensitivity, just the power consumption is lower for the 7M, about
60
mW less. That's 0.12 Ah per day when running on a '12 V' accu and
a
good DC/DC converter.

suggested this one. He said that delivery time is 20 days.
