Hi Stefan, You need an automatic variometer. A phase meter that steers a motor which turns a variometer coil inside your main coil. On LF i had a very high Q system and has to use such an application
Hello Paul, See the circuit of the M0BMU tuning meter. In attachment. This device is useful for itselfe. Over the years i built 3 of them :-) You will always see if your antenna has a capacitive or a
Hi Stefan, I have seen that M0BMU circuit before, as part of a larger document from which I built my scopematch. I would like to see your circuit for steering the motor. This will give me something t
Hello N1BUG, http://www.chriswilson.tv/vario-driver.zip The isolated ground is a mod someone suggested, not a Stefan idea!! I have built it but not tried it as i have yet to make the limit switches f
