K4 Highlights #2:  Transverter Band Displays & Dual-Transverter Receive

Like the K3 before it, the K4 provides extensive support for external transverters. The K4 adds several important new wrinkles:

1. Up to 12 transverter bands

Each transverter band has a corresponding button in the band selection group. Each band can be customized for lower band edge (up to 99,000 MHz), IF (0 to 53 MHz), oscillator error offset (+/- 99.999 kHz), and power level (0.1-5.0 mW). XVTR buttons display their lower band edge in MHz.

2. Convenient switching between HF and transverter bands

When you tap the BAND button, you'll see the currently selected band within either the HF or XVTR band group. An additional button will be labeled either XVTR or HF, allowing you to easily switch to the last HF band if you were on XVTR, or XVTR band if you were on HF. VFO A can be on HF while VFO B is on a transverter band, and vice-versa. If the sub is on you can monitor both an HF band and an XVTR band at the same time.

3. Independent dual receive with two external transverters (K4D)

If you have two external transverters, you can use RX ANT 1 for one and XVTR IN/RX ANT 2 for the other. With the sub RX on, you can then listen to both transverters at the same time, with stereo audio. You can then use the SPLIT control to determine which transverter is selected for transmit. (For this purpose, you'd need to drive both transverters' IF inputs from the XVTR OUT jack.)

The transverter band feature will be available with release 18 of the firmware, due out soon.
