Propeller Beacon Update

I have taken the baseline beacons that I have created for QRSS, WSPR and Opera and put them together into a single beacon.

WSPR is on a 10 minute cycle (TX Percent = 20%).  QRSS follows and just sends my call sign.  Opera then follows and the remainder of the 10 minute cycle is idle.  WSPR goes first because it has the even minute starting time requirement.

I have created each of the beacons as separate objects that the main beacon code can instantiate and call.  The main beacon code looks like this:

  _XINFREQ = 5_000_000

  WMin     =       381        'WAITCNT-expression-overhead Minimum

  WSPR  : "ko7mBeaconWSPR"
  QRSS  : "ko7mBeaconQRSS"
  Opera : "ko7mBeaconOpera"
  Clock : "ko7mClock"
  Freq  : "Synth"
  LONG Sync

PUB Main
    WSPR.doBeacon               ' 2 minutes (110.6 seconds) for WSPR
    delay(10000)                ' Delay 10 seconds before doing QRSS
    QRSS.doBeacon               ' QRSS is about 3 minutes
    delay(10000)                ' Delay 10 seconds before doing Opera
    Opera.doBeacon              ' Opera is about 3 minutes
    repeat while Clock.getSeconds // Sync

PUB doInitialize
  Sync := 10 * 60               ' Beacons cycle every 10 minutes

PUB delay(Duration)
  waitcnt(((clkfreq / 1_000 * Duration - 3932) #> WMin) + cnt)

The beacon is up and running as of now.  I would love to have any reports if anyone is able to spot any of my three beacons.
