[linrad] [Fwd: beta-MAP65 using]

GM all,

Ermanno, IK7EZN, replied directly to me about his first tests of MAP65. 
He wanted to include some screen shots, and this list does not permit 
attachments.

Ermanno's message will be of interest to others, so I am forwarding it 
to the list without the attachments.  I have posted his screen shots on 
the WSJT web site, and you can access them from the following links:

I will reply to Ermanno's message in a subsequent email.

Hi Joe .
This morning I have tried for the first time "on-line" MAP65.



1) As soon as shaped the program didn't decode . The PC with Linux and 
Linrad didn't have the time sincoronizzated, but as soon as fact then 
MAP65 has begun to decode.  Does MAP65 use the time of Linrad that 
receives in the packets from the network or that of the pc on which run 
MAP65?

2) The frequency of MAP65 is superior as regards the real frequency.This 
morning for example transmissions to 144.116 came suitable to 144.117 
like 144.109 to 144.110 [etc]..

3) The  DT seems to be around between 1.5 and 2 inferior seconds to what 
it should be.

4) The RX-noise indication does thing point out? I have seen between 4 
and 5 dB

 I attach you any files from which you could see any errors of decodes; 
for example in the BAND MAP comes brought again like a CALL the OOO 
relationship or part of a text free envoy at the end of the qso.

The first impression is extremely positive particularly way the 
management of the automatic polarization also on signals that I was not 
able to see on the screen of Linrad.

I have written directly to you because on the mailing  I don't succeed 
to send attached files.

possible improvments:
 1) Set tx-frequency as QSO Freq. even using the same routine of the 
Linrad (users_tr.c)
2) syncronize the time from a PC to the other so that they have lined up 
perfectly or ignore the time sent from Linrad completely.
