I don't know what the frequencies are on youtube so you will have to explore a little bit.
As far as manually running a sweep. You can control the f165 from either your computer or manually. The person you bought it from should have given you an installation cd. If not, there is one on Antlier Robin's website.
This is to run it manually.
1. Turn on the f165.
2. sellect menu key.
3. Hit bottom arrow to "New File".. press enter.
4. "Touch edit to start editing" should appear. Press number 0, (edit written on bottom).
5. line 1/1:..... hit enter.
6. This is where you start selecting the stuff you want. I generally start out with the duty cycle or offset. I guess it's better to run a positive offset. Anything set at 51 or greater will register as a positive offset in manual mode.
-Hit the up arrow until you get to "offset" and press "enter".
-"offset value" appears. sellect 51 or greater and press "enter".
7. Next press the number 7. It reads add right below the number to add the next line.
8. line 2/2: I generally sellect the duty cycle next. This determines how long the square wave is on relative to it being off. So a duty cycle of 50 means it's on 50% of the time and then off 50% of the time. I have read that more harmonics are generated at higher duty cycles of 60 and 70. So, I generally use a duty cycle of 70 so lets try that. This will mean the square wave will be on 70% and off %30 of the time.
-Line 2/2: hit enter. Use up arrow key to reach duty and hit enter.
-duty value: type in 70 and hit enter.
8. Hit add key.. the number 7 and enter.
9. Now I would here sellect the dwell or the pulse function.
I don't know the best way to use the pulse function. Higher and lower pulses I don't know which works best. I have had better luck with a pulse of 8-16. I don't know for sure but I think it determines how many times per second your frequency will turn off and on at a given duty cycle.
For example a pulse of 5 would mean a particular frequency will turn on and off 5 times per second with a duty cycle with it. Most of the time it is duty cycle is set at 50 but I use 70.
-Toggle down to pulse and hit enter.
-select how many times per second you want frequency to pulse. ex. 5.
-select your duty cycle.. 70.
12.Next it's time for the dwell function. This is essentially the time in seconds that each individual frequency is going to be run on. It's measured in seconds. Since you want to run a sweep then the dwell will be the time each frequency is run within your sweep. Lets sellect 10 seconds for example.
-Hit up arrow to dwell and hit enter.
-type in 10 for the 10 seconds and hit enter.
10. Now you're ready for the sweep function. The sweep function is setup so that it starts with the lowest frequency that you want to use and then it ends on the highest one. All you do is sellect the frequency range that you want to use. For example let's use 1000 to 1050, there is a spread of 50.
The function is looks like "sweep lfreq hfreq change of freq." ex.. sweep 1000 1050 2.5.
The 2.5 is the incremental increase you want to sellect for the sweep or the step up.
-hit add (#7 key) and enter.
-hit top arrow to reach sweep and press enter.
-"sweep start" is starting frequency.. ex. 1000
-"sweep end" is ending frequency.. ex. 1050
-"sweep step" the incremental step you want.. ex. 2.5. and hit enter.
11. The program is ready to run. However it doesn't run when you hit run. sellect "edit" (#0). "F165 ready" should appear. From there you sellect the "run" key.
Some other features. If you think you have a hit and want to continue to run on a certain frequency then hit the hold key (#8). This will cause the f165 to run at the frequency it's on when the key is pressed.
The pause is self explanatory.
If you want to save the file after you run it or before. When the screen reads "F165 ready" hit the menu key and toggle down to save file and press enter. Then you can label it. I never figured out how to get letters to label the file so I just use numbers.
The electroherbalism site has a list of many frequencies.

It's a good start. Best of luck.
