After you snip the wire and move the jumper what does this radio do? Here is what we have found so far. In no particular order.

1. Frequency Coverage. From 24.715 though 30.105 inclusive.

2. 12 Bands. The Bands have 45 channels with the alpha channels showing up with an ‘a‘ between the large channel read out numbers.

3. Addition of 2 further menu options in the menus accessed from the long press of Channel Selector. Rename the Band and reset the band. (We have renamed A band to CB but have not investigated what reset the band does yet. (Possibly just revert the name change back to the original letter.)

4. Ability to rename the bands. There is an additional function accessed via Channel Selector that allows you to change the band identifier from one letter to something else. It is called ‘Band Name’ and is located between EMG 2 and PA Set in the menu.

5. Band Scroll using the F button. A quick push of the F button scrolls through the bands. Here is a list of the bands

A. 26.965 to 27.415    Normal USA CB band
B. 27.415 to 27.855    Freeband or Hi 1
C. 26.655 to 26.955    Low 1
. 27.865 to 28.305    Hi 2. Oddly on my radio the D did not show! Are they all like this?
E. 26.065 to 26.505    Low 2
F. 28.315 to 28.755    Your 10m Ham band
G. 25.615 to 26.055    No Comment!
H. 28.765 to 29.205    Some more 10m Ham Band
K. 25.165 to 25.605    What happened to Band I? Why the Jump?
I. 29.215 to 29.655     The rest of 10m Ham Band
L. 24.715 to 25.155    You will find the 12m Ham band in here. And where did J go?
J. 29.665 to 30.105     Somewhere nobody goes.

Perhaps if I was to reset all bands in the menu it would revert to consecutive band letters but I would much rather it reverted to consecutive frequencies instead of jumping all over the place. Why do they program it like this? So counter intuitive. More later on this. Useful? Well yes, but a pain in the butt as well.

The other big change is the SPAN function. When activated in the Menu it gives the option of stepping in 100hz, 1khz, 10khz, 100khz, and 1mhz. It changes the step by consecutive short presses of the Channel Selector switch. A line under the number in the Frequency Display shows the chosen step.

When the SPAN feature is turned off a short press of the Channel Selector jumps the frequency up 5khz. Another press reverts to normal. The frequency display shows the correct frequency and a ‘DOT’ appears at the bottom of the Channel readout directly above the SRF letters.

You can’t step in 5khz steps but at least there is a way to get there quickly, albeit at the expense of the ability to change steps without turning on the span function in Menu. Then you lose the 5khz jump! I think if you are tuning about you should just stay in the 1khz step mode and be done with it.

POWER. The power doubles in expanded mode. We set our radios to 8w AM Carrier and increased the AM modulation, 20w FM and increased the FM deviation to 5khz which sounds way better, (Out of the box the deviation was between between 1.5 and 2khz, possibly to comply with EU standards?) and set the SSB at 25w PEP. We also had to make a few more adjustments to the SSB.

I will have to take a few things up with president about the state of tune of these radios from the factory but will wait till we complete checking the entire shipment before we do.

There are probably some more features we have not discovered, but these seem to be the main ones that affect the usage and are not covered in the manual.

My biggest beef at this stage is the small frequency read out and the way the F button scrolls through the bands in a silly order. Still have had no time to get on the air with it mainly due to lack of band activity and the need to go mobile as my present location is not conducive to using a radio on air.
