AND the radio. AND the computer. Those having RFI issues should run, not walk, to buy N0AX's ARRL book on grounding and bonding, and STUDY it. Also STUDY the slide deck for talks I've done at ham radi

If I needed a rig in that price class, it would be a Kenwood. They are second best to Elecraft, which is much more expensive. 73, Jim K9YC

Yes, have the same #4 wire connecting the house ground with the station ground. Both antenna masts also bonded. Learned that from this website!!

And is your ground rod bonded to the house ground too? Mike W9MDB

It depends on how susceptible the USB cable is to RFI. Mike W9MDB

I should have come back to the group sooner. I didn't get an e-mail that my original post was answered. Anyway...bingo! Yes, when I reduce power, (down to 45 watts) even on the upper bands, the radio

Mark, I’m new to WSJTx but for ham radio in general, I have 6 copper ground rods, 6 feet long bonded with #4 gauge wire and many would consider that inadequate grounding. One rod not enough. Gary N8GT

Question. I’m using an old Kenwood TS 850s, and thinking of getting a second radio. I am considering an ICOM 7300, but noticed how cheap IC 718’s are at the present. Any comments good or bad using the

One more thing...just to be clear, I am experiencing this issue on my portable CHAMELEON MPAS 2.0 which only has a radial coming from the antenna and my universally grounded (copper rod) antenna in my

Does the problem go away if you reduce the output power to near zero and/or transmit into a dummy load? If so, it's almost certainly RFI. 73, Willie N1JBJ

I just got back to the group. My shack is grounded to a copper rod buried in my garden. All radios, amps, tuners etc are wired to the same copper rod. 73 Mark KK2L

Good Afternoon All, I am having this same problem but only from 18mhz on up. On 14mhz down, the rig (IC7100) interfaces normally and well with WSJT-x and FLRIG. Icom radios do have a one USB cable, as

Sounds like the classic issue of RFI. Most likely caused by Common Mode Current. In most cases, grounding or earthing won't correct the issue. On the other hand, bonding all chassis together is the co

Hi, I have the IC-705, It will almost certainly be RFI. I was lucky, I had a well screen cable from other experiences with RFI I used a screened double ferrite cable from a Digital Camera. On Amazon:

It is a common problem with nearly all ham gear, because connectors are mounted in such a manner that they fail to bond cable shields to the shielding enclosure (chassis) at the point of entry. This m

I will echo this assessment. In my case, it was a short USB cable to a Raspberry Pi. A one-foot cable and generic snap-on ferrites have not fixed it. I ended up changing the direction of my loop which

I purchased an IC-705 to use for digital mode QRP operation. Quickly found out that my IC-705 is very sensitive to RFI coming in on the USB port, and did the same thing yours does. I was able to decre
