Has anyone out there added the 12 and 17 meter coils to their Butternut HF6V
vertical? I added the coils this weekend and got the SWR on 12 and 17 to
below 2 but the 10 meter SWR when out of sight! It was 6 plus and I could
not tune it in. I removed the coils and the SWR on 10 dropped back down to
1.2. Anybody had similuar experiences and if so, how did you resolve the
problem?

Thanks

Hi Larry,

Where did you put the 17 Meter coil? Was it butted up to the top 30 meter coil clamp? Then you adjusted the top of the coil to the lowest SWR?

I don't remember where I put the 12 meter coil but neither of them affected the 10 meter coil band setting of the stinger.

Good luck and hope you get it to work.

Tnx,
Bill, K5LN

I was fighting the 10 Meter tuning to no avail.
Finally zeroed in on the 12 Meter Coil.
Was going to remove it but instead totally compressed the 12 Meter Coil.
Problem solved.

As I found out in the HF9V manual:

NOTE: you can measure then adjust 15 and 10 meters at the same time since they donâ€™t interact like other band adjustments. This may help save some time and effort when tuning.
The 12M coil MUST be compressed as much as possible upon initial tuning. If not, it is highly probable that 12M will actually be tuned into 10M throwing the ability to tune 10M at all.

73 guys, I can now get back on 10 Meters
