Greetings,

After seeing Don WA4IML's post ("This is interesting. My 1220 has the
following birdies:") I went back through and listed everything that broke
the squelch with a dummy load connected. Here's my list with approximate
strengths (squelch set to approximately 11:00; just quiets on blank
frequency):

Frequency       Approximate strength
143.240         weak (i.e., barely breaks squelch)
143.350         strong (squelch at 3:00 to quiet)
143.600         weak, choppy
144.000         strong -- probably 4.00 crystal harmonic
144.050         strong
145.350         strong
145.395 or .400?        strong
146.050         weak
147.350         moderate
148.000         strong -- probably 4.00 crystal harmonic
148.050         strong

Other notes: frequency coverage 142.995 - 149.000; ROM rev. unknown

Any thoughts, guys?

73, Al
