All,
The SUNSDR PRO II have an open collector to switch / PTT a power amplifier. This means switch time is very fast I guess we talk about Nano seconds.
In the software the TX delay in CW is not present anymore. Even using my Juma 1000 amp that is QSK capable, relays have 5ms switch time, I am concern for hot switch of my amp.
Solution:
1. Use a winkey to solve this issue
2. Will there ever be a time delay setting again in the EESDR software, if yes we have a solution.
3. In N1MM+ you can set timing like I.E. 20ms PTT before you actually start to send. Is this something you could trust, if yes then we have a solution.
What is peoples thought about this, I have tested N1MM to generate CW, I have forced the software to have real-time priority and it works ferly well. Anyhow it sound good, but
it do not take long to burn out some relays in the amp if switch time is an issue.
Any comments please
