Hello, do you know how to build a 1:1 current balun for this transmitter for a dipol antenna? I have problems with sheath waves. At the internet I only could find current baluns for 1-60 MHz.

What's the unit of PO (Power Output, presumably) shown on the display of the transmitter? It displays 300 on max setting!

Hi, I see there are two jacks, one green and one pink. Are they the speaker/headphone and microphone inputs respectively? Thanks.

Does this thing support RDS (or does the chip responsible for modulating the signal do, so that you could inject something there)?
