Wanted - 50-60 khz transmitter

[Black Cloud]

I need to supplement/replace some lost or outdated signals, and would like to buy a 1 watt transmitter, in the 50-60 khz range, sine wave. My plan is to lay the antenna wire on the ground and transmit the frequency into the ground , replacing the old naval transmitters that I can't seem to find anymore. I am not a tech, but I have an BK precision # 3031 audio generator, and was thinking of getting an old 1 watt amp and hooking the generator to the amp, then using the wire antenna in the out terminals. I would rather just buy one from someone that knows a little about radios and stations.

Hmmm, interesting problem. I was looking at the posts from the guy in Turkey that was using a German instrument that operated in that frequency range. Looks like an interesting concept. Here are a few issues I see.

Would a watt near your receiver be too much signal? Maybe lower power would work.
An audio amp won't work very well outside of the audio range.
The FCC might not like you transmitting at 60kHz.

I guess there aren't any other stations you could tune to? WWVB ?
A low power transmitter wouldn't be too hard to build.

If no luck here, try over @ the Geotech site. Gobs of great information and techs to lend a hand.

That guy in Turkey has the identical instrument. It works well in Europe, and I'm sure other places around the world. Just not in my backyard. Yes, it is an amazing piece of equipment, and I am making plans to go to germany for professional instruction and will sell the product. The new model has it's own transmitter, just for places where there may not be a suitable signal, for whatever reason. The engineer has given me the details of it, and that is what I am trying to duplicate here. The transmitter will be placed at least 150 meters from the area of survey, so I am not picking up the primary signal, but the secondary. I will deal with the FCC. Oh, the 1 watt of power was the top end, hopefully will not need that much. When you say the audio amp will not work past it's range, I do not understand what you mean. That's why I am asking for help and cannot do this myself. I was told that I needed to connect the amp to the generator. The perfect solution would be to have a 50-60 kz radio station. I suppose. I have tried and cannot seem to pick up that station in Ft. Collins that you mentioned. Thanks for your interest. If you would like to put something together for me I will compensate you as you see fit.

60kHz is the frequency for the WWVB NIST Time Signal.

If you happen to interfere with that signal, expect the FCC to break down your door, sieze your equipment, and toss you in the hoosegow. The FCC does not give warnings, nor do they have a "sense of humor".

Homefires, you need to go hide in the closet since you live in fear. No one is going to kick down my door and seize anything. You would be well advised to discontinue your threats and mind your own business. You see, I don't have a "sense of humor" either.

It seems that a "sense of humor" is not the only thing you are lacking. Homefires was only passing on some friendly advice. With today's Homeland Security crap going on, you just might be surprised at what would get your door kicked in.
Kind of reminds me of that scene in "The Fifth Element" when Bruce Willis's next door neighbor mouthed off at the security cops and ended up being hauled off in a bag.
Homefires is just trying to keep you from getting "bagged". But..............go ahead on with yourself. Catch ya later.

The FCC will not bother you for alot of things, but I do not think they would like you transmitting on a government time signal freq......I realize 1 watt is not alot, but still...

But if you were to use an existing radio station's signal...??
