I can only change mode once when I boot CT 9.63. Mode change works fine with alternate CI-V control program. Frequency and band changes seem to work OK. Running DOS 6.22 on a 486. Is there a bug or cockpit error? 73, Bob, N4CU@AMSAT.ORG -- WWW: http://www.k1ea.com/ Submissions: ct-user@contesting.com Administrative requests: ct-user-REQUEST@contesting.com Problems: owner-ct-user@contesting.com
