If you see "ERR VCO" on VFO B after attempting a VCO CAL, it could
indicate that the new firmware load process did not complete.
Specifically, some data needed by the K3's synthesizer may be missing.
It is stored in something called the "FPF" (front panel flash memory).
If you see these errors -- or if you hear anything odd when tuning the
VFO, such as disappearing background noise -- you should try re-loading
the FPF data.
To do this:
1. Make sure you're running K3 Utility version 1.1.4.1 or later (do
Help/About K3 Utility).
2. Try re-loading everything a second time by clicking on "send all new
firmware to K3".
3. If you don't see any error messages after the load, try the VCO CAL
again.
If that doesn't work:
1. In K3 Utility's View menu, turn on Advanced mode.
2. Click the Load checkbox for the FPF component (right after MCU).
3. Click on "Send Checked Items to K3". (If this button is grayed out,
try turning Advanced mode off and back on.)
4. Turn Advanced mode back off.
5. Try VCO CAL again.
If this fails, please contact [EMAIL PROTECTED] and include in the
e-mail the following:
- your K3 serial number
- the present firmware revisions loaded into the K3 (as indicated by
either K3 Utility or from the K3's CONFIG:FW REVS menu entry)
- the entire "Activity Log" text from K3 Utility (you can drag the
mouse over the entire contents, starting at the top and going down and
to the right, then do ctrl-A to copy it, then paste it into the e-mail)
tnx
