ARRL mail forward problem. WB7OUT 19 hours, 2 minutes ago

Hi Terry,

Your forwarding address is set to n6aj@arrl.net. It should be set to one of your email accounts.

Another misconception is that the ARRL supplies email accounts to members--email accounts are provided to HQ staff who need an account to correspond with members.

ARRL mail forward problem. WB7OUT 1 day, 7 hours ago

Hi Tom,

I sent a test message yesterday and it presumably got there--I didn't get a bounce from our email server. The most common error is to address the mail to @arrl.org, rather than @arrl.net.

Need some help with MFJ-925 auto tuner ... speedmaster 1 week ago

According to the manual (page 1-12), pushing the H/L key (14) should reduce the power to 1/10 for external autotuner tuning.

I suggest getting the MFJ-5114A radio interface--according to the MFJ-925 instruction manual, it will allow the user to control the tuner with a simple push of the [TUNE] button on the front panel.

Alternately, if you plan to operate digital modes, it may be practical to use the digital mode setup to send a low power carrier as required by the tuner. It sounds like you are trying to use a weak voice signal to tune up--the modulation on your signal is confusing the simple SWR circuitry--it takes more sophisticated circuits to tune up with an amplitude modulated signal.

single element radiator verticle/velocity factor KC5LUR 1 week, 5 days ago

What are you using as the other half of the antenna--the radial or ground plane the whip is working against? Not surprisingly, the ground system has a significant impact on the tuning of the antenna.
