Re: RS Whip
John, I constructed the RS back of set antenna as seen in the files section. I made a small wire-ring jumper for bypassing the coil and with the bottom two sections out and the top section 2/3 rds

MP-1 / AP-10A / antenna mounting hardware for FT817
Barry W4WB wrote: Now you have me intrigued, Barry! How did you mount your B&W AP-10A on the FT-817? Is there a new B&W FT-817 mount, or did you drill out the stock one? Is the AP-10A different from

RS Whip
Whilst at local Radio Shack, I picked up a telescoping whip antenna which extends to 72" for <$5. Thinking of adding either a BNC or PL- 259 connector to the end. With a counterpoise, it should work

Re: At least one MP-1 which is not so hot.
Very true. I think Yaesu would have done us all a favour (well, maybe not the manufacturers of expensive portable whips, but the rest of us) if instead of putting that tempting BNC socket on the

Re: An MP-1 that is very hot
Mine is that at the frequency where the Q is highest (hence strongest signals) the impedance is not 50 ohms. As I de-tune the antenna, the impedance changes and appears to give a better match.

Re: At least one MP-1 which is not so hot.
Peter, I think you make sensible points but ones which miss the point. The MP1 and the ATX are SUPPOSED to work nder suboptimal condx when taken out and about with a PORTABLE rig...the 817. Your

How do you take an MP-1 apart
Howdy All, I bought an MP-1 at Dayton and I would like to store the various pieces in it like I saw Vern do at the 817 gathering but I am not sure how to take it apart. I didn't want to
