SNR on 20 and higher bands is lower but it could be location more than anything (or induction on air-core choke)... But 40 is hopping and I get low SWR on all bands below 40 so far, so I think this might be a win for portable.

Didn't expect this janky-arse speaker wire NorCal doublet with air core balun/choke to work at all, especially with feedpoint at 18 ft above ground level. But I just made a solid 5-7 SSB QSO with a #POTA station about 230 miles (371 km) away on 40m.
