Choyong LC100 tuning the MW AM band using Tecsun AN200 passive tunable loop antenna

by OfficialSWLchannel

📚 Main topics

Testing the LC100 on mediumwaveThe presenter tunes the Choyong LC100 across the mediumwave band, using a Tecsun AN200 passive loop antenna to receive stations including CFRB 1010 Toronto and WBZ Boston. 0:00
How the loop antenna helpsRotating the AN200 helps select between stations, and its distance from the radio reduces noise from the display. The S-meter also makes it easier to tune the loop for maximum signal. 2:04
Reception problemsSome signals jump between strong and weak, and the radio appears to struggle when two stations share a frequency. The presenter speculates that the behavior may involve the antenna interaction or the radio’s DSP and AGC processing. 1:02

✨ Key takeaways

External antenna improves performanceWith the AN200, the LC100 can receive mediumwave stations well, but the presenter says the radio needs the external loop to perform properly. 10:29
Internal antenna limitationsThe presenter says the LC100 sounds good on mediumwave but is nearly unusable for this purpose with its internal antenna. 6:49
A strong-station demo is not the whole pictureThe presenter cautions that videos showing only strong signals may give buyers an overly positive impression and fail to represent the radio’s tuning behavior across the band. 7:20

🧠 Lessons learned

Show the radio’s real-world behaviorThe presenter argues that reviews should disclose performance issues rather than rely on carefully chosen examples, so listeners can make informed decisions. 7:54
An external loop can be a workaroundIf you already have a Tecsun AN200 loop, it can help the LC100 deliver decent mediumwave reception despite its quirks. 10:29

🏁 Conclusion/next steps

More radio tests plannedThe presenter plans to take the Choyong LC100 and a Tecsun loop outdoors for a radio outing and says more shortwave videos are also planned. 11:00

Get these crispy chicken nuggets. >> So, uh, welcome to the shortwave radio channel. We're on mediumwave. And you might noticed I'm listening to CFRB1010 Toronto with a really good signal. And there's a reason for that.

0:30 I have paired the LC 100 with the Tecsun AN200 sorry um loop antenna with of course this cable uh that is here and it's uh hooked to the radio up here. So that's what gives me a very good signal as I'm tuning around on the medium wave band with the Choyong LC 100. Um all is not perfect. There are a lot

1:02 of frequencies where the signal is not as strong where the signal seems to like jump around. What I mean by jump around it's it's there. It's not. It's there. It's not. It's like if there's the AC has some kind of issue trying to bring it up and when it's getting too high it drops to zero. Um, it's kind of weird. Is it an interaction with the antenna itself? Is it some kind of weird interaction within the radio with two strong signals on medium wave? I don't
