Counter Problem To: ham-homebrew@ucsd.edu I have an older model tube general receiver with analog tuning. To improve my tuning accuracy I hooked up a frequency counter by taking a tap from the oscillator plate line using a 1 uf 1 kv capacitor. The lead was sent to the frequency meter and the ground of the meter was connected to the ground of the radio. This arrangement works exceptionally well (7 decimal place accuracy, as long as I remember to subtract the oscillator's frequency from the meter reading) except on 3.3 to 5.6 MHz, where I get no reading on the meter. However the oscillator is obviously working since I tune in stations effectively and the analog frequency reading appears to correspond to the stations' announced frequencies. Could anyone hazard a guess as to why the anomaly for 3.3 to 5.6 MHz? Thanks for any suggestions.
