Here is something to ponder. Doubling your transmit power nets you 3 dB gain on transmit. Improving your antenna by 3 dB, whether by improving the gain or reducing loss, nets you 3 dB on transmit AND

NOT TRUE! The received signal is a coherent source, while ambient noise is incoherent (random in phase), so you will definitely se an increase in signal to noise ratio. This is unlike adding a preamp

Do electolytics have a particular failure mode when they go bad over time? I assume that the dialectic is drying out and they just gradually loose capacity - lower uF's. Does the voltage rating decre

Then why do some amplifiers' manuals tell you to monitor the grid current and give you a meter function for that purpose? ? 200uA / c. 1100? ? Monitoring grid current is of zero value because tune-up
