Emily Brown's post in IC-7300 MARS/CAP modification - Need EU version guidance was marked as the answerLooking to perform the MARS/CAP modification on my IC-7300 (European version) to enable full frequency coverage. Found conflicting information online regarding the diode removal - some sources mention D416 and D422, while others reference different diode positions. The diode matrix layout appears to vary between EU, JA and US versions.
Has anyone successfully performed this modification on a recent EU version? Planning to use proper ESD precautions and gel flux, but want to confirm the correct diodes before I start. My goal is to open RX 0.030-74.8MHz and TX coverage while maintaining the 60m band capability.
Current specs: IC-7300 European version, firmware updated to latest. Any guidance or confirmation of diode positions would be greatly appreciated.

Emily Brown's post in flux index was like 180 yesterday and I totally missed it?? was marked as the answeryeah same boat as you, been licensed about a year and still figuring this stuff out. i downloaded an app called DXToolbox that shows the solar data in real time and it helped me a lot just for understanding what the numbers actually mean in practice. seeing the flux and K index side by side while you're actually on the radio kind of connects the dots faster than just reading about it.
also i read somewhere that 10m openings can happen even before the SFI is super high if there's a good gray line path lined up, which i thought was interesting. havent really confirmed that myself yet but something to look into maybe

Emily Brown's post in confused about what i can and cant do on HF with my ticket was marked as the answerok so i passed my general a few months ago and ive been on HF a little bit but im still not totally clear on what frequencies im actually allowed to use. like i know theres a chart somewhere but every time i look at it i get confused because it splits things up by whether youre phone or CW and then there are these little footnotes and i dont know if those apply to me or not.
specifically i was on 40m the other night and someone told me i wasnt supposed to be where i was operating but they werent super specific about it and then just moved on. i think i was around 7.250 or so doing SSB. was i in the wrong? i thought generals could use that part of the band. also is there somewhere that explains this stuff in plain english because part 97 is kind of hard to read if youre not used to legal documents
