Re: M57713 144-148mHz module
Hi.
The driver transistor gives 250mw at 50ohms and I've directly connected it to the output connection that went to the PA module. Had some reasonable reports on FM & SSB using the radio that way. Adding a 2SC1972 as a PA and biassing it suitably you get around 3 Watts on SSB plenty enough to drive a 30watt Linear amp, even with 3 Watts with a decent antenna I get up to 20 miles on FM.
