Graham,
I guess that in theory the 500Hz version should be better (FM with a better modulation index ?)
But only if noise is uniform.
What about a simultanious session ROS-EME / JT4C ? Both have about the same bandwith.

Thanks Rik
Well that was not supposed to happen .. hihi .. Jose had expected the 500/1 to give the best copy .....

Will reduce to approx 2.5 Watt's per stream at 2300 local
Tnx for reports G ..

As of 21-15 local time power set ..40 watts per data stream (may be too much ?)
NB : Pls run x2 session's of ros for comparative test
Will run till round midnight
Thanks for the reports via the email system and the ref

ROS EME
ROS 500 Hz / 1 Bit speed
Dial set 502.000 KHz USB
Dual reception by running two sessions of ROS . , set eme and HF 500 rx 1 bit speed
select the minimum AFC range
The HF 500/1 bit should out perform the eme mode
Reports welcome via ref or the auto email mode
Note - Due to low af drive level - NO RX -
Tnx - G .
