Thanks for that Jim,

Seems its close between the mfsk and throb systems , I found the throb mode=20
worked best last night
may be its down to the noise format , but  psk31 appears to of produced the=20
highest error rates at
all  locations , Rik reporting the throb system printing quite  well

Tnx- Graham .
