2018 - it abruptly went off the air just as i was finding the best Kiwi receiver.
2019 - carrier back on with no modulation.
2020 - intermittent music and then carrier off, then carrier back on - seems to be switching an amplifier on/off.
2022 - lots of nice bass, high cut at 8Khz, sharp brick-wall type - music/carrier keeps cutting out - power level fluctuating up/down.
2024 - abruptly off - assuming the OP is having some troubles or testing - hope you get them resolved and working to your specifications
2027 - strong S7 carrier on my Kiwi

- immediately following music (i rarely get any HF pirates on my Kiwi due to my location)
2029 - AM modulation on the upper side of the carrier
2033 - AM modulation now both sides at 10Khz bandwidth (5Khz audio)
2051 - iron maiden "run to the hills" live in concert (carrier off/on)
2102 - weak carrier underneath @ 6923.990Khz (very likely unintentional)
heard best on Victor, NY Kiwi -
