When inputting program search data, there is no entry point for step-adjust, however it is still possible to enter step-adjust data following the programming sequence.

Enter program search data as per section 12-7 (pages 51, 52, 53) of the English language operating manual. Activate the program search in the usual manner by pressing

then select the required bank as directed at the end of section 12-7 (page 53).

The new airband channel step comes into effect in 1999 and 2000 for most of Europe and is to be further extend after that time. There is much confusion over the issue of

8.33 kHz, in reality it is not 8.33 but eight-and-one-third. As a third cannot be expressed in a decimal fashion, a small compound frequency error will occur every third

increment. Ideally the end digits should read '00' '33' '66' '00' but will be display as '00' '33' '66' '99'. In reality, the AR5000 may be programmed in 8.333 kHz steps to

further minimise the compound error, the error is then very small indeed, especially when considering the sub band is only expected to occupy 132.000 - 134.500 MHz (one

Hz every third tuning increment!).

Work around:

If you do not wish to live with a small compound error, it is possible to program three program search banks as a GROUP (refer to section 12-4 Page 49 onward of the

English language operating manual). It is assumed in this addendum that you understand how to program basic functions.

1. Program three program search banks with the limits 132.000 - 134.500 MHz in AUTO mode (AM 25kHz steps). Link all three search banks to form a single group... so

all three are searched together. The operating manual does not specifically deal with step-adjust during program search, so ignore it at this time. Let's assume you have

used banks 1, 2 & 3.

2. Bank 1 is left 'as is'.

3. Start searching bank 2. Press

As there is no step-adjust entry point during the data input of program search, this LONG HOLD of the

the above fashion. The AR5000 will continue to search but will add 8.33 kHz to every 25 kHz increment.

4. Repeat the process outlined in (3) for the third search bank, in this example (bank 3) but use a step adjust value of 16.66 kHz.

The AR5000 will continue to search but will add 16.66 kHz to every 25 kHz increment.

Outcome:

By searching all three search banks as a group, the exact frequencies will be searched for the new airband allocation without a compound error creeping in. As the

AR5000 has 20 search banks (twice), using three banks in this way is no great loss.

SWITCHED EPROM BANKS - more memories!!!

The facility of switching EPROM banks is now supported by the AR5000+3

(see the main operating manual section 18-6, page 71, last two items).

This virtually means that the AR5000 now has 2000 memory channels,

40 search banks, 10 VFOs etc... two sets in one!
