ELECRAFT K3S
SEARL # 11821
10 WATT AMPLIFIER WITH THE FOLLOWING OPITIONS
KTCX03-1 MODULE
KB3F3A GENERAL COVERAGE RECEIVE
KRX3A HIGH PERFORMANCE 160 _ 6 METER TRANSCEIVER
RADIO WAS ALL TUNE AND CALIBRATED BY WILCOX ENGINEERING W3DVX MAY 2023
Work completed:
Completed “LPA Protection Diodes” mod recommended by Elecraft.
- Checked the battery: should be okay at 3.03 V.
- Checked that the 10W max power output is within specs on all bands. Noted that 52MHz is typically a bit lower than all the lower bands.
- Listened to CW and SSB (MH-2 mic with bias) at max output.
- Changing between CW and SSB caused an unexpected 600-Hz freq shift: Resolved by tapping “5” in the menu item CONFIG:CW WGHT.
- Completed calibration procedures below:
Calibration procedures per manual:
- Save start configuration. Done 4/27/2023.
- Verify you have latest firmware as downloaded from Elecraft. You now have current 5.67 MCU; 1.26 FPF; 2.88 DSP1, 2
- Are there hardware updates recommended? Did LPA mod (above)
- Verify CONFIG:TUN PWR and CONFIG:PWR SET to “nor”
- Check installed-filter positions and offsets. (FL1) 13kHz___(FL2) 6kHz___(FL3) 2.7kHz, -0.88, 0 db___(FL4) 2.1kHz___(FL5) 500Hz, -0.72, 4 db
- Set (if desired) power-on banner. “K3BPF”
- Test and calibrate Synthesizer. n/a with KSYN3A
- Wattmeter: 5W, 50W, 1 mW Calibration. Done using LP-100A for 5W and 1 mW only..
- TX Gain Calibration on all bands. 5W, 50W, 1 mW. Done for 5W and 1 mW only.
- Reference Oscillator calibration using Method 2 (Zero-Beating) with 20 MHz WWV. Done.
- Set Front Panel and PA temperature sensors. FP set to 17 deg C when cold.
- Calibrate RF Gain. Low level and high level. Done for Main and SubRx.
- Check/adjust S-Meter at 50 µV and 1 µV levels using Elecraft XG3 at 10 MHz. Done.
- Check/adjust ADC REF parameter following Tech Mode instructions. Done, 4.97V.
