[ADXA] mshv issue

Hi,

Looks like people are desperately trying trick mshv to get in the 
KP5/NP3VI log without actually hearing the station (especially on 160m 
where their TX is poor). So, keep calling for a bit and then send R-xx 
(xx any number) and the chances are that you will end up in the log 
(without actually decoding anything). Mshv remembers for a while that it 
responded to you and will accept happily the R for quite some time.

I wish they would implement a short timeout for mshv so that it would 
not accept the R after say 1 minute of getting the call. This would not 
eliminate this loophole but reduces the chances of it working. But even 
then we would probably start seeing sequences of alternating call & 
roger transmissions.

This ends up being a similar issue as people using online remote RX to 
receive (no need to hear the DX).

ps. This is not just happening with kp5 but other peditions as well.
