BOG antenna on PL-360 v.s. stock PL-310-FARMERIK
This is just a preliminary comparison. The '310 has a better reputation for receiving AM stations than a '360 when only the supplied stock antennas are used. The '360's ferrite rod is external and plugs in via an 1/8th inch telephone jack, making it easy to connect external antennas and bypass any internal ferrite rod without cutting into the insides of the radio. When I connected the '360 directly to several wire or large loop antennas in the past, it picked up SW broadcast stations when the radio was tuned to LW and the lower parts of the AM BCB.
Today I had help to run 500 feet of wire on top of the ground.[BOG=Beverage On Ground Antenna] A suitable matching transformer is on its way, but not used in this test. I connected only the long wire to the '360's phone plug tip connection. It seemed to work very well on AM. On LW there were stations I have never heard before, but some sounded like images of SW broadcasters. I will have to sort that out another day.
Both these radios have a 4 digit [RSSI] read out. The first 2 digits are Signal strength, and the second 2 are Signal to noise ratio. In both cases, higher is better, but the last 2 digits are better indicators of a listen able station in my opinion.
The first number will be the frequency in KHz
next will be the figures from the readout on the PL-360 connected to the BOG
the last will be the same figures from the PL-310 without an external antenna

This test was done 1 to 2 hours after local sunset. I skipped frequencies on which I could not hear an easy to understand signal on the PL-360. Often nothing could be understood on the PL-310. As you can see, there are 3 groups of 5 stations in different parts of the AM BCB.
