Would it be possible for the Portsdown 4 button 'Pluto power' to remember the setting depending on the transmission setting?
S2QPSK or DVB-T
Like it does for different frequencies...

Pluto power output DVB-T
Re: Pluto power output DVB-T
Power setting remembering power levels between output modes.
The reason I ask is because when you transmit with a Portsdown 4 both DVB-T and DVBS or DVBS2 there is a big difference in power output from the Pluto. With DVB-T set at -6 output power then switching to DVBS the output is much more! It needs to be reduced to something like -15. This could cause someone to overload their linear amplifier if going from DVB-T to DVBS without thinking.

Re: Pluto power output DVB-T
Hi Martin
I recognise that this would be a useful feature and that it appears simple, but it is quite complex to implement in a fool-proof manner. It would need minor changes to at least 6 files and major changes to another 3 (including the touchscreen logic and the transmission script), followed by extensive testing.
Given my other current committments (including BATC Treasurer), I do not anticipate being able to implement it in the near future.

Re: Pluto power output DVB-T
Thanks Dave,
I understand but it was worth asking. During this experimenting with DVB-T down here in Cornwall due to GB3NQ getting DVB-T in the future, the problem with switching between the two modes has been found. You probably have already heard. If you switch from dvbs to DVB-T and back you will eventually get the Pluto to transmit rubbish for a while before having to be reset. Alan G3XPY spotted it and we all confirmed the problem.
