When I'm out and about mobile, I generally have at least one VFO scanning about 40 channels on 2m and 70cm. The 2m FM calling frequency (145.500) is one. But generally, I seem to end up making QSOs via the repeaters. This works well and I have lots of fun and interesting contacts.
This weekend I decided to leave one of the VFOs on 145.500 and make lots of CQ calls! It yielded a couple of decent contacts. Yesterday, from one of the lanes around the village, I worked a SOTA station M0TUB/P on the summit of Cleeve Hill near Cheltenham. And today, when I was driving back from Mum's near Cheltenham, I had an excellent QSO with Giles G0NXA across the town and up and over the Cotswold escarpment. I wonder if a few CQs on 145.500 on the daily commute will bear any fruit?
