2014 Radio Checkup Clinic
The NSARC meeting held on January 2, 2014 provided the opportunity to do
basic testing of members’ radios using a HP8921A Communications Service Monitor.
There was an enthusiastic response from the members in bringing in equipment for
test. Our members Alex VE7DXW and Adam VA7OJ ran the radio testing session.
