[TenTec] 1220 "birdies" revisited

[wb5jnc@juno.com]

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
