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, <br>

      The cheap ublox GPS modules are used by many LF amateurs as a 1

      at
      amazon, relatively cheap. <br>

      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
