Hi Tony, Ken put that in a version of version 8 for me but I never did get it going. It is supposed to work by using the -loop option. I am still interested in it but havn't had time to get back to trying it out again. Could you please let me know what you find out about it? Thanks, 73 and good luck, Fred KE7X (ieefc@msu.oscs.montana.edu)
