That's AWESOME Bob, I've never in my life seen a "CB leenyar" so professionally done! I don't know about that high power 196KHz amp, as far as I can see from here your LF band is this:

2200 metre band plan, 2200 meter band plan.

135.7 - 137.4 kHz Morse code (CW) only.

135.7 - 135.8 kHz International long distance (DX) communications window.

135.8 - 136.0 kHz Test transmissions and test beacons.

136.0 - 137.4 kHz Normal Morse code (CW) operation (centered on 136.5 kHz).

137.4 - 137.6 kHz Narrow band digital transmissions e.g. PSK (centered on 137.5 kHz)

137.6 - 137.8 kHz Slow Morse code (CW) transmissions e.g. QRSS.

The Aussie (Australian, Australia) 2200 metre band is 135.8 kHz – 137.9 kHz (0.135.8 MHz – 0.137.9 MHz) using narrow band modes of transmission (such as Morse code and narrow digital transmissions) with a maximum antenna radiated power of 1 Watt effective isotopic radiated power (1 Watt e.i.r.p.).

To achieve the legal antenna radiated power of 1 Watt EIRP with the normal low efficiency low frequency antenna it is necessary for the actual transmitter output power to be much higher than 1 Watt.

In January 2009 the Australian Radio Frequency Spectrum Plan was amended by the Australian Communications and Media Authority (ACMA) to create the first Low Frequency amateur radio band in Australia.

Low Frequency radio listeners can use free to download computer software to see on their computer very low power radio signals over large distances as well as radio signals under the noise.

This band was made available to radio amateurs worldwide in the International Telecommunications Union (ITU) World Radio Conference (WRC) in 2007.

From June 2009 the 135.7 kHz to 137.8 KHz band is available to all holders of the Australian Advanced Amateur radio license by applying to the Australian Communications and Media Authority (ACMA).

By the end of 2009 or in 2010 the ACMA will allow use of this band to all holders of the Australian Advanced Amateur radio license without the need for Amateur Radio Operators to specially apply.

Australia’s contribution to the successful worldwide adoption of a new amateur radio band in 2007.

Then there's this:

130 kHz – 190 kHz is the 1750 meter band (1750 metre band).

The Kiwi (New Zealand) 1750 metre band is 130 kHz – 190 kHz (0.130 MHz – 0.190 MHz) using all transmission modes with bandwidths under 6 kHz such as AM voice transmission, Narrow Band FM (NBFM voice transmission), SSB voice transmission, CW (Morse code) and narrow digital transmissions with a maximum antenna radiated power of 5 Watt effective isotopic radiated power (5 Watt e.i.r.p.).

Due to the low efficiency of low frequency antennas the actual transmitter output power is much higher than 5 Watts.

Incremental Frequency Keying IFK was first suggested by Steve Olney VK2ZTO and is seen in the Jason software (in the Italy section). DominoEX (IFK+) is a computer-based radio mode intended for simplex chat-mode (real time keyboard chat) operation on the lower frequency bands but is excellent from LF to VHF.

DominoEX allows perfect copy of 77 words per minute Morse code with 260 Hertz bandwidth

DominoEX is tolerant of drift and frequency error.

DominoEX has improved robustness in NVIS propagation conditions especially against multi-path effects that are common at night on low frequencies.

It looks like you'll have to source information on VLF operation first?
