LF: Re: Dual Mode WSPR Beacon running

[Andy Talbot <andy.g4jnt@gmail.com>]

The dual mode WSPR Beacon is now off.  

Checking the overnight hits, I'm rather pleased with SM2DJK at  1908km on  the slow 15 minute mode

As expected, the 2 minute signals yielded lower distance reports

My 137kHz dual mode WSPR beacon is running.  It randomly alternates between WSPR-2 and WSPR-15 mode (shifting frequency appropriately)

Two callsigns are in use,  G4JNT on -2 and G8IMR on -15,   this allows differentiation in the WSPR database.   I see there are already spots from both modes in WSPRNet

EIRP is about 0.3 Watts

As it shifts randomly between modes, there may be an appreciable wait between the faster -2  transmission slots when it is sending -15 and then wating to resync its 2 minute sequence - be patient
