Operation Quiet Fear N6XJP 3 weeks, 2 days ago
Dear OM,

"Operation Quiet Fear" was an April Fool's Joke that was published in another Amateur Radio magazine. There is no need to worry.

Welcome to the A1 Operator Club forum NC1L 4 weeks ago
It does not matter which term is used. Some operators may not like the term, "Control"; "Facilitator" sounds less controlling to those who don't like being told what to do.

This topic has nothing to do with the A-1 Club.

I'm sorry you have experienced this difficulty.

I have forwarded your trouble to our IT department. In the future, it would be best for you and other members to call Headquarters if this problem occurs. The Lab is the only department that regularly monitors the forums and we get to them when we can, but calling is faster. 860-594-0200.

Thank you.

What is your question?
HW101 Xmit set-up KD0ZGW on 25/3/15
I own an HW-101. I have it here in my office.

1. in receive mode (SSB), adjust the Driver/Preselector for maximum hiss in the speaker.
2 Place Meter switch to "REL PWR"
3. Set the "Load" (lever) control at minimum (three o'clock)
4. Place 'mode" knob to "Tune"
5. Rotate plate knob for maximum relative power.
6. Advance Load control and adjust plate knob to increase power output.
7. While still in the Tune position, readjust the driver control for peak relative power output. Touch up load and plate controls again.
8. Move Mode knob to the appropriate SSB mode.
9. On the meter switch, switch to "ALC"
10. Adjust the microphone gain so the meter moves off the pin rest a little bit on voice peaks.

Note: Do steps 4-7 quickly. Do not tune continuously for more than 10 to 15 seconds. If the maximum power is not reached, switch off the Tune Position for 30 seconds, then resume tuning. Once you're familiar with it, tuning up goes quickly.

Note: Make sure you use a dummy load when tuning up. This not only eliminates interference to others, but it gives your transmitter a 50 Ohm load. Once tuned, you can then switch to an antenna tuner and tune that. If you try to tune up into an un-tuned antenna, you will be tuning the rig, the antenna, the rig....you'll be chasing tuning forever. Use a dummy load first.

It is best to run your 40 to 50 year old rig below the maximum power it can put out. I run mine at 80 Watts on 80, 40 and 20 meters. On 10 meters, the output is typically around 50 to 60 Watts.
