Thank you for the QSOs.  They are appreciated!

K7RI is a single tower one transceiver station usually active in most major contests.  Recently the contesting has been in the multi-single category with a handful of operators that share operating time in individual shifts.  In the past almost all the contests were entered in the single operator category.

80/75 Meters          2 Quarter wave slopers
                               Counterpoised on the tower at 40’ (~12m)
