 Johnny, VR2XMC, points out that some DVRs were delivered with memory chips that supported only 10 seconds for a recorded audio message. Let’s change the last paragraph to read:

 1.1.1    KDRV3 Digital Voice Recorder

The digital voice recorder allows you to record messages for playback, handy for contest operating, and there is also a memory for general recording of received audio. There are eight playback memories, each of which can record up to 15 seconds of speech for playback. The receive recording memory is a 90 second continuous loop. (Note: Some DVRs were delivered with memory chips that supported only 10 seconds of speech for playback; most, it appears, support 15 seconds.)

Thanks Johnny, VR2XMC and David, M0XDF

The internal K144XV two meter transverter address should be trn0.

 

After installing the K144XV, the setup needed is the following.

1.    Choose a transverter band 1 – 9. Let's assume you choose band 1. For each of the config menu items tap 1.

2.    Set CONFIG:XV1 ON YES.

3.    Set CONFIG:XV1 RF 144.

4.    Set CONFIG:XV1 IF 28.

5.    Set CONFIG:XV1 PWR L 1.00.

6.    Set CONFIG:XV1 OFS 0.00.

7.    Set CONFIG:XV1 ADR Int. trn0

 

In about April 2011 Elecraft started delivery of the K144XV Reference Oscillator Phase Lock Option to solve some drift problems in the 2 meter operation. Let’s change the following paragraph:

 

Setting an Offset

The config menu item XVn OFS allows you to calibrate the K3's frequency dial to the actual transmit and receive frequency based on small errors in the local oscillator in the K144XV. For example, suppose the local oscillator is off frequency by 1.5 kHz. With this, when you tune to a 144.000.0 signal the K3's display would be 144.001.5. The offset is accurately measured at the Elecraft factory and printed on the K144XV module cover.

1.    Tune the K3 to a frequency between 144.000.0 and 145.999.9 MHz.

2.    Set CONFIG:XV1 OFS to the value given for the OFFSETS 144 MHZ on the module cover.

3.    Tune the K3 to a frequency greater than 146.000.0.

4.    Set CONFIG:XV1 OFS to the value given for the OFFSETS 146 MHZ on the module cover.

(Note: If you install the K144XV reference oscillator (offered by Elecraft to solve some drift problems in about April 2011), the offset calibration procedure is changed. Please refer to the K144XV Reference Oscillator Phase Lock Option installation instructions for the up-to-date procedure.

Thanks Johnny, VR2XMC

 The key pictured there is a HEXKEY, not a HEXKET.
