For the past few days, I've been attempting to use a Yaesu FT-1000MP with WSJT-X using FT8 and WSPR on 30 and 40 meters without success at transmitting or making a contact. I can receive others just fine, but nobody can hear me (including wsprnet.org and pskreporter.info). If I set mode to AM or FM and toggle MOX, output power shows up as 0-100W (depending upon the position of the "RF PWR" dial... though I hit 100W with the "RF PWR" dial only a quarter-turn clockwise (9 o'clock position)). If I set mode to LSB or USB and toggle MOX, output power is shown as zero, regardless of the "RF PWR" dial's position. When transmitting FT8 and WSPR from within WSJT-X, output power is shown as zero, regardless of the "RF PWR" dial's position. If I enable "Mon" (green LED illuminates), I can hear the allegedly-transmitted audio... but it sounds kind of "scratchy" (for lack of a better word to describe it). If I connect the audio output from the US Interface (now Timewave) Navigator to an amplified speaker instead, it sounds perfectly fine. I've tried it with the Navigator's audio output set to both -0dB and -15dB. It definitely sounds better in 'Mon' at -0dB, but the radio's output power is still shown as zero either way. The Navigator's audio output is connected to the radio's PATCH jack on the rear. The Navigator's audio input is connected to the radio's "AF OUT" jack on the rear. PTT is via CAT. I've tried "non", "rig", and "fake it" for split... same outcome with all three. According to time.is, my computer's clock is spot-on. I have two antenna configurations: For 30 meters, it's a 60" 3/4" diameter type M copper pipe + MFJ-1620 hamstick, with top whip replaced by ~6' Buddipole telescopic whip, extended to approximately 4'4". According to my NanoVNA 2.2, SWR near 10.130MHz is 1.14:1. For 40 meters, it's the same lower copper pipe + W3FF Buddipole coil (no taps selected) + same 6' Buddipole telescopic whip, fully-extended. According to my NanoVNA 2.2, SWR near 7.074MHz is 1.08:1. I have two pairs of radials... one has a pair of 7.5m wires, one has a pair of 10m wires. Both pairs run more or less north and south, and are constrained by a parental dictate (I'm visiting them for two weeks) that they have to remain entirely within the side yard's landscaping bed (I had to dig and bury a conduit for the coax so the landscapers wouldn't mow over it). When transmitting with the meter in "SWR" mode, I've only seen a single bar (the leftmost one, above "1.0"), which AFAIK, indicates that the internal antenna tuner has gotten it to be flawlessly 1.0 The automatic antenna tuner is active. I cleared its memory, and explicitly hit 'tune' at 7.000, 7.200, 7.074, 10.100, and 10.140MHz, so SWR should be flawless. Any ideas about what might be wrong, or what to check next?
