Need toroids

[email protected] All Messages By This Member #9907 A bit off topic but... ? I'm running Direwolf with an Easy Digi and a Kenwood TH-F6. RF feedback has been a problem that I have confirmed by running on a dummy load while near another station.? I think I saw a Toroid kit mentioned somewhere but don't have a clue as to what forum. Any suggestions? ? Thanks Dave WB9TEN ?

For a 2 Meter issue, I would use one of the following materials: 31, 43, 44, or 46. Make sure your data cable is fully shielded.? Jim Bacher, WB8VSU wb8vsu@...?

glen english LIST All Messages By This Member #9920 开云体育 you'll find up to 6 to 10 beads (in series)? on a wire effective, most likely.? Don't stop at two and think that's all that can be done. or , up to say low VHF wind the wires through each core? twice for four times the inductance. At higher frequencies, stray capacitance between the wires kills this advantage. glen On 28/09/2024 3:04 am, Don Rolph wrote: toggle quoted message Show quoted text I ordered these ferrite suppressors: and used them liberally on all wires: ?sometimes?2 on each end, On Fri, Sep 27, 2024 at 12:45?PM dtmenges@... via <dtmenges=[email protected]> wrote: A bit off topic but... ?

[email protected] All Messages By This Member #9922 Thanks for the input. Because Kenwood recessed the mic and speaker inputs, I used an extension to make the connection at the radio. I have no idea how good the shielding is in the extension. I think I purchased from Amazon and it was cheap. Since then, I have acquired the extended plugs that should work directly into the radio. I think I'll see if I can eliminate the extension first while the beads and toroids are on order. ? Again, thanks for the help ? Dave ?
[email protected] All Messages By This Member #10019 I am now going direct from Easy Digi to the TH-F6 (extension cable not used). I have also installed multiple toroid style chokes on everything but still get RF buzz. When running on the battery, it sounds pretty clean. My power supply is a recapped Heath HW-202-1 and I have tried a 20 amp switcher with similar results. ? The good news it that it appears to be reliable but annoying and will always be a pebble in my shoe. ? Thanks for the help. If anyone else has an idea, I am all ears. ? 73 Dave WB9TEN
