Re: Eagle and P3E



Hello All
When we had S band on AO-40 we were able to cobble together a number of good receive systems   Through a variety of web sites such as W0LMD and K5OE and others we learned what to do.  It appears we now will need another "watering hole" of information for 5cm.  Some commercial units (downeast) can be pricey.  I for one would like to start well in advance.  So-where do we start?
