How do you find a specific station? Someone just told you that Radio Australia is on 9580 kHz in the mornings and you've always wanted to hear them. You could use the ETM, but you don't know if you can hear them at all. You could always choose the SW band with the up/down arrows, then start tuning with the wheel. It can still take a long time to find stations in those bands, though, so I've adopted a trick I learned about in a video about the radio. I sat down one afternoon and started saving entry points roughly every 100 kHz into these SW bands. Take the 31 meter shortwave band: the charts say that it starts at 9400 kHz and goes to 9900. I tuned to 9400, pressed MEM, then tuned the wheel up to 9500, pressed MEM, and so on, stopping at 10,000 kHz instead of 9900 (because 10,000 kHz is the time standard station WWV). Now if I want to listen to Australia on 9580 kHz, I just hit the VF/VM button to go into memory and tune the thumbwheel up to 9600. Hit VF/VM to go back into manual tuning, and then tune down to 9580. Of course, I could have gone to 9500 and tuned upwards, but that's much farther than going to the 9600 and tuning down. This video is a good overview of all that I've talked about here.
As for weak points, while it's an impressive performer and I can mitigate not having a numeric keypad somewhat, it still uses that tuning wheel a LOT, and I suspect it as a part that might wear out first. It desperately wants either a keypad or a computer control bus, but has neither. It has a USB B connector on it that is used to charge the board batteries (I put NiMH batteries in it - it takes 3), so I plugged it into my PC hoping to hear the Windoze sound that it found new hardware, but no such luck.
