2016 Radio Checkup Clinic
The NSARC meeting held on May 4, 2016 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.

The summary test results are given in Table 1 below for those who missed the meeting. These
should not be regarded as definitive due to the informal nature of the tests.
This year, only VHF/UHF radios were presented for testing.
