What's that 7809 IC?
Actually it's the TSR 1-2490 - TRACOPOWER DC/DC CONVERTER I have discussed here.
I have used it just because it costed me good money and I had it around but I would not advise anyone to go that way. Purchasing a good 7809 (from the A series) is likely a safer bet. There's a risk the DC/DC converter may interfere with the TX module nearby, we will see.
