Hi,
i've a se 550-42 ( 400-425 mhz band).
I've installed pa4den software with succes.
My problem it's in the hardware:
1) if i connect on a db15 on rear the micro of my se 540 (same pins assignements) they are no modulation
2) if i transimit in 400 -425 mhz band i've more then 8 watt, if i transmitt in uhf ham band 430-440 mhz , the power goes down to 0,5 watt.
I've tuned the tx and rx vco at middle band 435 mhz and in simplex channel band 433 mhz without result..
Do you have some suggestion for me?
many thanks
