And I see nothing about everything in your station, including the computer, having their chassis bonded together. And NO grounding or bonding wires should have ferrite beads on them. Buy and study N0AX's ARRL book on Grounding and Bonding, to which I contributed, and/or the slides for my tutorial on the topic. http://k9yc.com/GroundingAndAudio.pdf 73, Jim K9YC

At some point in the not too distant I will be running the 50MHz 100W Beacon PA (the very one described in RadCom this month) using MSK144 , continuously transmitting a test message at 100% duty cycle. Antenna is an HB9CV at ground level pointed directly upwards from my Loc. IO90IV58 It'll run for several hours from perhaps midnight through into dawn, which seems to be the best time for meteor pings. No doubt there will some other periods of test transmissions. Actual centre Frequency 50.377MH, use an SSB carrier / tuning point (the so-called dial frequency) of 50 .3755MHz This is at the top end of the band allocated to MS Where is the best place to announce this? WSJT-Group, obvs, but anywhere else? It's been suggested I place a message on ON4KST, 50MHz chat and / or then spot myself on it The signal will be directly generated in a PIC + AD9852 DDS combination. Andy

The oddest thing about this is that it only happens with WSJT-X. I can do voice on 40m no problem with 1.2 SWR.FT8 (and other WSJTX modes) are FSK (continuous power) modes; SSB is not. FT8 will generate as much as 10x as much RF voltage on the shield of the feedline as SSB. It is the magnitude of that voltage that causes problems with the USB ports of computers/rigs. 73, ...

Mark-
You are probably not sending audio through the PC when doing SSB. Also ground your PC as you do the other gear. Since this problem just developed, check for loose or corroded connecters and make sure a critter has not chewed your antenna lead. Also run a bond wire #6 minimum form your station ground rod to the ground rod at your power meter. It is required by National Electric code. Thanks Dan KC2STA

I am writing today about an issue I am having with running FT8/FT4/other WSJT-X modes on 30m and 40m bands. This is an issue that just developed within the past few weeks for me, as previously I had been able to transmit on 30m and 40m no problem. My rig is the Xeigu G90 using the CE19 interface running into an external USB sound card on my HP Omen laptop running Windows 10, build 19043.1288 (21H1). I also use the XPA125B amplifier and tend to run FT8/FT4/others at around 35-50 watts depending upon band conditions. I use an Chameleon Emcomm III-B end-fed dipole with a MAT-TUNER mAT-125E external tuner. My SWR tends to hang around anywhere from 1.1 to 1.4 in normal conditions. I pair to WSJT-X using FLDigi and use CAT control. I still have no trouble operating on 10, 12, 15, 17, 20, 80 and 160, but over the past month I am unable to run more than 10w on 30 or 40 meters without the transmit immediately stopping on me. As soon as I start to increase power, I notice the SWR climbs to as high as 1.7. The amp is capable of running with SWR of up to 3.5 (know that isn't good for it though), but the transmit stops. I have also noticed power fluctuations of up to 70w when this happens. I have checked all connections and grounding and everything looks good. Antenna configuration is a half square on my roof and again this was working fine before this month. Any ideas what is happening? I am on the latest release of WSJT-X.

Any ideas what is happening? I am on the latest release of WSJT-X.This is not a WSJT-X issue. *ANY* end-fed or off center fed antenna is highly unbalanced which will turn the feedline into an unintentional radial with RF currents on the *outside* of the shield. You will need to *decouple* the feedline from the antenna by installing an effective *COMMON MODE CHOKE* between the feed line and antenna and, perhaps, installing a second *COMMON MODE CHOKE* where the feedline enters your shack. I recommend the information on common mode chokes at: <http://k9yc.com/publish.htm>. In particular, "RFI, Ferrites, and Common Mode Chokes For Hams" and "Transmitting Chokes For 160-10M" 73, ...

Re: new version 25 doesnt switch ic9100 to usb-d mode

Bruce N7XGR
I can not understand what this problem really is because all three USB-D filters can be adjusted to user preference. Page 73 of the IC9100 user manual describes on how to adjust the filter widths. In fact I prefer FIL2 because I have it adjusted to a wider setting. Just follow the instructions on page 73 and all will be fine. Also the regular 3 USB mode RX filters can be adjusted the same way. Remember that since this 9100 does not have a SD card for saving settings it is advised to write down all settings that have been changed by the user. Print out the SET mode pages out of the manual and make your notations accordingly along with any TX and RX filter settings. Bruce N7XGR

Just put in a patch that should re-use the existing filter if RIG_PASSBAND_NOCHANGE is requested. So at least once a filter is selected it should stick. Mike W9MDB

Mike,
WSJT-X always requests a mode change
with no change in the filter settings. I know this is somewhat
problematic with some Icom rigs that do not allow reading the
filter settings on the SPLIT Tx VFO without swapping VFOs. Perhaps
those that want to use the Icom default filter settings and can't
be bothered to customize them as needed should be forced to put up
with VFO swapping when changing modes in SPLIT, so Hamlib can read
the current filter settings and honour the RIG_PASSBAND_NOCHANGE
option by reading the current value to reuse just before setting
the mode.
Note that WSJT-X always requests a mode
switch (possible redundant) when setting the frequency, this will
not change as it copes well with inadvertent operator mode changes
via the front panel.
