Using the KPA100 on 60 meters: The KPA100 can only be used on 60 meters if it includes recent
modifications (see page 2). Otherwise, it could be damaged. Note: Normally, the 40/30 meter low-pass
filter on the KPA100 is used on 60 meters. This filter rolls off aggressively above 10.15 MHz. Combined
with the KPA100's excellent PA balance, this results in adequate 2

-harmonic rejection when the K2/100

is operated from 5300-5500 kHz. However, a future application note will explain how to modify the
KPA100's 80-meter low-pass filter to work on 80 and 60 meters. This would provide much better rolloff if
needed. The D 1 9 menu entry can be used to select which KPA100 low-pass filter to use. When editing the
D 1 9 parameter, tap

D I S P L A Y

to select P A 6 0 = 8 0 or P A 6 0 = 4 0 (default). Leave D 1 9 set for

P A 6 0 = 4 0 , even when using KPA100 kit revision C. (See Important Operating Notes on pg 19.)

Channel Hopping and Scanning (Applies to HF and Transverter Bands)

Channel hopping, if enabled, allows you to use the VFO knob to quickly hop among just those frequency
memories which fall into the present ham band. You can turn this mode on or off on a per-band basis
(default is off). Channel scanning—among these same memories—can also be enabled on a per-band
basis. It will work in either the original K2 scan mode (receiver muted) or in "live scan" mode, where the
receiver is not muted, and scanning doesn't stop until you touch any switch. To use these features:

1.

R C L

memory #

to see if it is set up for 5000 kHz (one of the original defaults). If it is, and you plan

to use channel scanning on 60 meters, you should store a different frequency in this memory (on a
different band). Otherwise you may hear WWV at 5 MHz during 60-meter channel scanning.

2. Set up and

S T O R E

two or more frequency memories within the target band (using VFO A). Frequent

users of 60 meters in the U.S. should set up memories 1 through 5 as USB, on the allocated channels
(5330.5, 5346.5, 5366.5, 5371.5, and 5403.5 kHz). Note: 10 frequency memories are available in the
K2, so using five of them on 60 meters will leave just five for other purposes. You can use fewer than
five on 60 meters if desired.

3. Choose one of the stored memories as an "initializer" to be used when starting channel scan on this

band, and

R C L

it. (For 60-meter users, this would typically be memory #

4. Edit the R A T E S secondary menu parameter. Tap

D I S P L A Y

to select C H S C (channel scan

enabled) or C H S C - T N (channel scanning and manual channel tuning enabled). Note: The n o r
(normal) setting of this parameter disables both.

5. Exit the menu, then

S T O R E

this memory (using the one you recalled in the previous step). If manual

channel tuning is enabled, you can now use the VFO to hop among memories assigned to this band.

6. To start channel scanning on the desired band, hold

R C L

, then hold the numbered key corresponding

to the "initializer" memory you saved earlier, e.g.

. Holding the numbered key for about 1/2 second

will show S C A N on the LCD. If you continue to hold the key for another 2 seconds, you'll see A F
O N , initiating "live" (unmuted) scan.

7. You may wish to program

P F 1

P F 2

as a scan resume function, using the PF 1 or PF2 menu

entry. This will allow you to quickly re-start scan from where it left off. As with the

R C L

method, you

can hold

P F 1

P F 2

for about 1/2 second to start normal scanning, or hold for an additional 2

seconds to start live scanning (A F O N ).

Using RIT and XIT with channel hopping: If you have channel hopping enabled, and you need to fine-
tune your operating frequency, simply turn on both RIT and XIT at the same time. The RIT/XIT offset
potentiometer will then function as a limited-range VFO control, moving RX and TX frequencies equally.
