Image shown is an ADF-60A due to similarities in appearance between units.

  • Remote mount ADF receiver
  • Typically used with ANT-60A/B combined sense/loop antennas, either 614L-11/12/13 analog controls or CTL-60, CTL-62 (w/ CAD-62) digital controls, and RMI-36 indicators as a system
  • DC sin/cos RMI output only
  • Completely solid-state, no rotating machinery
  • Coherent detection to demodulate bearing signal for reduced bearing errors and safety hazards caused by adjacent channel signals
  • Automatic band switching for ease of frequency selection over entire operating range
  • Audio muting and pointer stowage with unusable signal
  • Digital tuning combined with single crystal frequency synthesizer
  • Digitally stabilized frequency synthesizer
  • Crystal filter selectivity
  • Modular construction
  • Same as ADF-60A but does not have 3-wire synchro output for use with 3-wire RMI units

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.
