Andy,
=A0
Quick Q .. is the=A0 reception software= capable of auto reporting to the=A0 5 meg group=A0?
=A0
I have an idea it has this=A0 facility=20= .or at least produces a -5 meg-=A0report file . if so can it be turned off ?=

Subject: LF: Multi-function beacon

I've now=A0started transmitting a timed=A0 beacon signal on 503.7kH= z that is=A0identical in format to that of GB3SSS operated over the winter m= onths of the last two years=A0=A0from Poldhu on 1.9 and 3.5MHz, =A0and has= =A0a similar signal structure to the 5MHz beacons, GB3RAL, WES and ORK.=A0 T= hese all have=A0an initial CW ident and=A0stepped power levels for aural rec= eption,=A0and a precisely defined period of full-power plain carrier for S/N= measurements.=A0=A0
See=A0 =A0http://www.rsgb-spectrumforum.org.uk/5mhz%20beacons= .htm=A0 for the complete 5MHz =A0signal structure.=A0=A0For this MF tran= smission, as on GB3SSS, the pulsed sounder sequence of the 5MHz beacons is r= eplaced with a PSK31 message which lasts from=A030s to approx 48 seconds aft= er the start
=A0
Auto Monitoring software writen by G3PLX is available for monitoring th= ese beacons, it measures signal to noise during the carrier period and saves= to file as well as plotting the last 40 hours worth of measurements.
The software can be downloaded from=A0 http://www.rsgb.org/spectr= umforum/hf/beaconauto.php=A0.=A0=A0 PSK31 data can be copied with Digipa= n, Fldigi, PSK31SBW or a host of other packages.
=A0
TIMING
The 503.7kHz transmission takes place every 15 minutes at 4 minutes pas= t the quarter hour.=A0
ie=A0each transmission starts at xx:04, xx:19, xx:34 and xx:49= =A0=A0=A0=A0This time slot has been selected so that the transmissi= on do not interfere with my continuous ongoing reception of the 5Mhz beacons= - the active antenna used for these is overloaded by the 500kHz signal and=20= I have already lost data when the WSPR beacon transmission coincided with on= e of the monitoring windows.
=A0
NOTE=A0=A0 If using the=A0G3PLX software, this only=A0monitors for the=20= three 5MHz beacons at =A000, 01 and 02 minutes.
SO IT WILL BE NECESSARY=A0TO FRIG=A0THE SOFTWARE =A0to= monitor this=A0transmission at the 04 minute point.=A0=A0=A0The necessary a= lteration can be done by firstly setting=A0your PC clock accurately to the c= orrect time, then setting the Track Time box to -240 (minus 240 seconds)..= =A0 This will make the software look for this transmission during the time= =A0window it thinks it would be receiving GB3RAL, and log the=A0MF transmiss= ion during the first minute, on the red trace, as if it were GB3RAL=A0
=A0
The beacon uses the identical hardware to the=A0WSPR transmissions of= =A0the last few weeks, with the the only change being a=A0reprogramming of t= he controller PIC.=A0=A0 In fact the very same hardware was previously loane= d to the Poldhu club for their beacons, with the only difference being a cha= nge to the final Low Pass filter on the output of the broadband PA.
