My FT-920 has some modest noise cancellation tools, I gather the fairly normal ones for modern radios. An adjustable passband DSP filter, a noise blanker and a variable noise cancelling control. I'm looking in two different directions for how to improve this, as I might TX better than I RX, at the moment.
There's noise-removal software meant to improve voice clarity, but it's meant to work on audio noise, not radio noise, much less the static noise floor of lower bands.
Not bad, not bad. I got a 7.2m fishing pole in from China today and used it to lift the far end of the EFHW so that much more of it is higher up and vaguely straight-ish. On 40m, I got picked up in Italy, which, given the orientation of the antenna, suggests I was going over the north pole to get there.
Furthest actual contact was 4000km, into North Carolina. That _should_ be in my antenna's null, but for a tail on the end bent south along the property line, so who knows?
Followup: I went out and pulled all of the slack there was in the coax, wrapped it around a tin can about eight times and duct taped it. It's a pretty terrible but traditional way to do a coax choke, and unlike the snap-on chokes this seems to have done the job. Mostly. I can crank out maximum power (just shy of 100W) and not crash anything, and the lights only flicker when dimmed.
Getting a #DXCommander soon. #EFHW are probably best suited to QRP, preferably POTA/SOTA.
@k5dru yeah, this EFHW was the best I could put up in the limited time before the winter storm rolled in. It takes a ton of reactance to tune and leaks RF everywhere. It's only meant to be a test for a field-deployable antenna for POTA/SOTA in the spring.
I'm going to order a DX Commander and be done with this nonsense shortly, though if it warms up above freezing I may try to find an angle where a very simple dipole works. Quite possibly leave both up, with an AMLA as well.
Took me a while to figure out how to get this radio into the right mode to both decode ft8 messages while also accepting the audio for tx. Yaesu has (had?) some strange ideas about the right way to configure this.
Here's what got me over the hurdle: https://wsjtx.groups.io/g/main/message/1036
Also, RFI is no joke. I have a bunch to hunt down and fix, and I think the EFHW is almost certainly spewing it back inside on tx (despite so, so many chokes), and it's causing the usb devices to crash...
