Hi guys, this is my first post on this forum, so bare with me if I ask something stupid.
I just bought my first plane, have joined a club etc, but.... my Tx has no buddy lead jack. I didn't think this would be a problem as I thought that I could just stick my crystal in my instructors Tx, along with on efor his master Tx. Is this possible, or have I screwed up? will I be stood there passing my Tx back and forward continually?

Thanks in advance for any clarification.
