When the voltages of f1 and f2 are out of phase, they cancel and the envelope is at a null. The IMD shown in table 1 is an optimized target figure and will vary somewhat with different tubes. I often refer to phase noise as the "aurora" affect. February 11, The Twin Passband Tuning used in conjunction with the two 1. Additional parameter information is available in reference 3.
In this case four audio channels are needed for 2 IF channels.
And, I don't feel like rehashing it here. AGC automatic gain control is a very important function in receivers. The needless interference levels are extremely high for many transceiver models, particularly when operated at reduced power. D Octave 70 87 20 F. Carrier supression is sometimes a problem, but can usually be retweaked. Well, the numbers are 6db better, but the actual figures are the same!! The sensitivity is about the same, as you would expect because TSD is really a great rig in its category, providing an excellent signal and a good reception in usual working conditions.
