Great video John. I bought a RS-918 brand new about a year ago. It really is a great little radio. Mine does have the built in battery. I use it to do POTA (Parks on the air.). I go to several different parks on my Electric E Bike and have a blast. My antenna is a Pac-12 ground mounted vertical. I also use this radio to do portable FT-8 and FT-4. while out and about. DE VE3WKG AKA VA3NE. 73.
I love this little radio, as I write this I am adding a new video with a new build (#45) for the 96khz band scope firmware... If you have not used this firmware you will be amazed at the improvements, the receiver is almost as good as my Yaesu FT-710. Please watch the video, it should be ready in 30 minutes.
I did belive i had to use Cw-L on 40m band 🙄 no wonder i cant seem to get the decoder to work, i have tryed all the filter like a 1000 times now, the decoder worked ones or twice...but when it work it seems to work well... 73 from LA-M160560
