During World War II, all Amateur Radio activities were suspended and the Club no longer functioned as such. However, there were seventeen members who maintained operating privileges under the War Emergency Service and were issued special callsigns. The calls used at that time were WKAV with Units numbered 1 through 17. Net activity was conducted on 2 ½ Meters using one-tube receivers and transmitters. Each of the seventeen was issued Black Out and Special Passes as part of the Civil Defense System.

After the war, the Club returned to service and continued active in Net operations on 2 ½ and 5 Meters, later changing to 2, 6, 10 and 75 Meters. Civil Defense, Red Cross and various Public Service activities of the day included The March of Dimes, Arlington Home Fund Telethon, Army Pick-Up Days, Cerebral Palsey and Muscular Distrophy Telethons and many more.
