This week I operated from several grid squares. EM25, EM26, and EM14 in Oklahoma.
It is very easy to operate mode J portable for several reasons:
- No need to adjust uplink frequency. You can camp out on a single TX frequency and only make adjustments to RX as necessary.
- No need to use a directional uplink antenna. 2m is far more forgiving. I was transmitting into a 19″ whip on the center of my roof, receiving on a 3 element 70cm yagi with a preamp.
There are trade-offs, of course, using such a setup. You cannot peak your uplink signal, for one, meaning you cannot easily stomp deaf lids and interference to SO-50.
