Need inexpensive spectrum analyzer
Can anyone suggest a decent inexpensive spectrum analyzer, that I can look for used on ebay, that would be suitable for evaluating SSB transmitter output for spurs, harmonics, etc.? I have a cheap RM Italy former CB amplifier that has been heavily modified to work on 80 through 10, and has a set of low-pass output filters in a box with a band switch, all of which I am using with my FT-817. Its provenance is suspect, at best, and I'd like to be able to check it from time to time to make sure its output stays clean. Also I have an old TS-120S that seems to have some serious transmit problems, part of which is probably spurs and harmonics and self-oscillation in the finals and God knows what else. I don't mind paying a fair price for a good spectrum analyzer but I don't want to pay big bucks for a high-end unit with features I'll never use. Thanks... |
