MFJ-949E Tuner with Comet SBB-5 Drennen 2 weeks, 6 days ago
Dear Drennen,

Check the specification of the MFJ-949E. You will see the tuner is designed to operate between 1.8 and 30 MHz. It will not work on 2 meters.

A good rule of thumb is to use a resonant antenna, when possible, so no antenna tuner is needed. There is no need to add a tuner if your mag mount antenna works well without one.

I used to use the same type of antenna when I lived in an apartment back in the 80's. I had a Larsen mag mount on top of a well seasoned baking pan. The outfit was placed on a flat roof, about 10 feet away from my shack window. It worked great.

Have fun,

Antenna Polarization for FM contesting Gringo6 3 weeks, 2 days ago
If FM is all you have, FM polarization is fine.

I appreciate FM operators during VHF QSO parties. FM contacts added to my overall score, each time I have participated. During lulls in the event, I always check out the 2 meter FM simplex frequencies (excluding 146.520 MHz). Those 20 or so extra QSOs can add to a serious contester's score.

It would be nice to see some new participants during contests. Maybe we should have an FM only catagory?

Our ARRL Laboratory limit for signal input is +10 dBm (10 mW). It is considered the highest "safe" signal input for test purposes.
