Yes. Because the VHF-22D is an extended range VHF comm radio, the CTL-22C control must be strapped to either allow or not allow operation above 135.975 MHz. That is, if it is desired that the VHF-22D only function in the VHF-22C frequency range, then the CTL-22C connection for ext. range (P1 little m to be exact) should not be grounded. Likewise, P1 m connection should be grounded when operation above 135.975 is desired.
8.33 refers to the kilohertz (kHz) channel spacing for VHF communications radios required in certain types of airspace. Normal channel spacing for VHF comm radios is 25 kHz. Currently, 8.33 kHz channel spacing is only required above FL195 (19500 ft.) in the ICAO European region as of 15 March 2007.

8.33 channel spacing was introduced and implemented to help reduce VHF communication overlap and congestion in high traffic areas in Europe. With dividing 25 kHz by 3 (thus 8.33), many new communication frequencies were created. Only very specific radio equipment is capable of channeling, transmitting, and receiving in 8.33 kHz increments. Some of the more popular systems include the Rockwell Collins VHF-21/22/422/C/D and Bendix/King KX-165A (-0201), KY-196B. The Garmin GNS-430/530 series systems are capable of 8.33 also.

The VHF-22C is only a direct replacement for the VHF-22A 25 kHz comm. The VHF-22C is not a direct replacement for the VHF-20A or VHF-21A radios as they have different mating connector styles. The VHF-22D is a direct replacement for the VHF-22B.

Southeast Aerospace exchanges are based on the return of an undamaged, economically repairable core unit with identical part number as the unit shipped to the customer. An "economically repairable" core is defined as one where the cost to repair/overhaul (or Repair Cap) does not exceed 80% of the original SV/OH exchange price billed. Should the Repair Cap exceed 80%, the customer will be billed the additional amount. In the event this amount exceeds the Outright Price for the unit, the customer would only be billed the difference between the Outright Price and SV/OH Exchange Price with the core returned as-is to the customer.

Here is an example of such a transaction:

$1000 Exchange Price charged to customer
$1000 x .8 = $800 Maximum Allowable core repair charge or Repair Cap

$2000 Cost to repair core unit
- $800 Less Core repair cap
---------
$1200 Additional billing amount.

2200.00 Total Cost of transaction

Please Note:
SEA offers exchange on new items as well. However, repair cap as indicated above is still based on SV/OH exchange price.
