I just worked W2AGN. I gather that the exchange is RST & some sort of membership number as well as state (or section?). RST/state/number ? I sent RST/state/power (I'm guessing 9 watts on 20m, but I think I have a QRO watt meter. I will cheerfully crank it up to 100w to complete the contact.H)Or is that last number a serial number? Conditions not great in eastern Iowa this morning. 73 Jan KF0Z/N0AAA #389
