Re: LF: RE: Syncback software QQQ

Yes. 

 

All it does is measure the total signal within the 25 - 30 second.  You could transmit for the entire one minute and it would still give the same reading.  

 

But avoid the preceding minute though, that's when the noise measurement is made.

 

 http://www.g4jnt.com/PCBCN.zip  will do the job if you can keep the PC clock accurately set, eg from an internet sync site

Hello Andy,

if I got it right the RX software will make a correct measurent as long as the signal is there during the 5 second period, even if the transmission start a few seconds early and stops a few seconds late ?
That would make timing far less critical and it would be possible to use my QRS software (eg. sending an "E" at 10 seconds dotlength).

Quoting Andy Talbot <andy.g4jnt@googlemail.com>:

No it uses the average power over the 5 second period.   You could always
start it 1s early and stop 1s later

 Andy,

Q .. If the  tx is keyed by vox/breakin    will the slight  clipping of
the  leading edge of the  beacon  cause time problems ??
reason being  .. if use force 'tx' will miss the  beacon rx windows ??

Tnx- G ..
