Has anyone attempted to put these rigs on 30 and/or 17 meters ? If so, are there any "quirks" I need to know about BEFORE I start adding crystals ? Also, what is a good source for crystals ? The manual says "series resonant" crystals but dosen't give a holder style/size. Thanks for any info and advise. 73, Rod Pruner, KN3ZOG Conyers, GA USA
