Title: ART-13 & Antenna tunner Post by: W1ZFB on February 10, 2023, 08:15:11 AM I just got my ART-13 operation and have made contacts on 40 meter with good reports. I now want to try 80 meters. I could not tune up anywhere on 80 or 75 meter band. I know from reading various articles you need to add capacitance. I tried my antenna tuner and it seems to load up okay now on 3.865 about 95 watts out. My question is there any harm in using the antenna tuner? Should I just use a single or variable capacitor like I've read in some articles.
Incidentally I have tuned up on 20 and 24 meters with no problems. Thanks Mike Title: Re: ART-13 & Antenna tunner Post by: SM6OID on February 11, 2023, 03:32:35 AM Hi! AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
This is what I do, I have added 1000 pF to the capacitor connection post. Other values will work, but I took what I had close to me, and it appears to work. Have also used a variable cap, can not remember the capacitance I used. Will a tuner work, yes, but it may complicate the tune up process Using a dynamotor, not feeding with full voltage, I see approx 115-120 W carrier at our phone part of the 80 m band. |
