Stuck AGC Meter
- January 18, 2008 - MCU: 1.58, DSP: 1.48
Just saw, that when you switch off AGC, the S-meter and receiver gain will stay at the level where it was at the moment when you switch off agc - for example noise at S4, switch off AGC - S-meter will still show S4 and gain is also reduced, switching off antenna before AGC off and antenna on again will show S0 and full receiver gain... -- dj7mgq at muenchen-mail.de

Don't set different Band/Mode on VFO B
I have VFO A on 6M USB and VFO B on 10M USB. When I turn the VFO B knob, the VFO frequency changes, but the mode changes to LSB. If I turn VFO A now, the VFO A frequency hangs and the mode goes back to USB. If I do a band down, I don't get 10M on VFO A, instead I still see 6M, plus get a PLL error message flash by.
Factory suggested workaround: don't put VFO B on a different band from VFO A until the subreceiver comes out. It will also switch in the bandpass filters for VFO B's band any time you touch VFO B.
When the sub RX is installed and this firmware issue is corrected, there's also a CONFIG menu item that needs to be set for setting the two VFOs to different bands. That menu item is VFO IND.
Caution - do not press the [SPLIT] button to go into split mode when you have the condition above.
If you do, you will disrupt the usual band sequence when you step through the bands.
Until Elecraft gets it fixed, be careful to not have different bands in VFO A and B.
IF THIS HAPPENS AND CAUSES THE BAND SEQUENCE TO BE OUT OF ORDER USING THE BAND UP/DN SWITCH, USE DIR FREQ TO ENTER A FREQUENCY WITH IN BAND THAT SHOULD BE DISPLAYED. THEN TAP A/B AND DO THE SAME FOR VFO B. YOU SHOULD DO THIS TO FIX ANY BAND WHERE VFO A AND B ARE ON DIFFERENT BANDS.

Reported December 9, 2007 MCU 1.45, DSP 1.43
Corrected in version MCU: V 1.48 DSP: V 1.45 11-07-07
If you set Mic Source to Line In and turn your K3 off and back on, the display will say that Mic Source is still set to Line In. It is not. You must set Mic Source away from line In and then back again. Bug acknowledged by Elecraft and is on the list to fix.
THIS IS FIXED IN FIRMWARE. MIC SOURCE IS NOW RECALLED BY WHAT WAS LAST USED BY MODE. - AB7R
Reported November 19 2007 MCU 1.34, 11-17-07
Corrected in version 1.35 MCU 1.35, 11-07-07
Nov 19 2007 CW MESSAGE RECORD: The message buffers were getting truncated before being completely filled (127 rather than 250 characters), and inserted word spaces were excessive in length. Message entry is far easier with the new version. Nov 19 2007 NOISE REDUCTION (NR switch): We've had a couple of reports of NR generating a very strong audio artifact when certain types of signals were tuned in. Since it could occur when you're wearing headphones, we ask that you avoid using NR until we get the new firmware out. THIS IS NOW CORRECTED IN FIRMWARE - AB7R
Nov 19 2007 VCO CALIBRATION: A few customers have seen an ERR VCO message with a parameter value between E00004 and E00013 displayed when doing VCO CAL (part of the kit alignment process). This only affects receive-only operation below 160 meters (i.e., with the KBPF3 general-coverage band-pass filter option installed). The next firmware release has an improved VCO CAL function that should correct this. If not, we'll send you a replacement synthesizer module. FIRMWARE WAS CHANGED TO INCREASE THE VCO RANGE DURING CALIBRATION. THIS SHOULD GREATLY REDUCE THESE CAL ERROR MESSAGES. - AB7R
Nov 19 2007 TX TEST: Off-air testing was working only in CW mode. It now works in all modes. It's especially useful in SSB modes, since it allows you to adjust your mic gain and compression without transmitting.
Nov 19 2007 2.7 kHz CRYSTAL FILTERS: If you have firmware prior to revision 1.34, you'll need new firmware in order to properly set up our 2.7 kHz 5-pole filters. NOTE: ALL 5-POLE FILTERS REQUIRE A NEGATIVE OFFSET PROGRAMED INTO THE CONFIG;FLx FRQ MENU ITEM FOR THE SLOT WHERE IT IS INSTALLED. YOU WILL FIND THIS OFFSET ON A LABEL ATTACHED TO THE SIDE OF THE FILTER. - AB7R
