I have acquired a TS-930SAT (late s/n 503xxxx) with a PIEXX board installed but none of the W6NL mods done (so far as I can detect). While I am waiting for a service manual I ordered yesterday I have one primary question: What other PLL issues can remain after the PIEXX board is installed? When I turn on the rig and step thru frequency segments with the 1MHz step buttons (which actually shift frequency in 500kHz increments) the receiver is dead on all segments except for 1.0 to 2.5MHz and 14.0 to 19.0MHz. The display does not blank although it will freeze and no other control functions on the front panel seem to work. Occasionally, when first turned on, I will hear a loud "pop" from the speaker and the LCD display flashes what looks like "PLL (something)" but it happens so quickly that I cannot read all of the display contents. Does the '930 have a "PLL Unlock" warning as part of it's diagnostics? I am hopeful that the service manual will shed some light on the subject. I have done a thorough search for PLL topics on the web but they all seem to refer to early s/n '930's. Thanks, in advance!
