hey guys, on the advanced modulator, how did you go about wiring SW2? I'm kind of having a hard time figuring it out.
See, There are only 4 contacts on the switch, but the schematic shows a common point J1:pos that contacts to either c or d and 9 V that contacts to either LED2 or LED3.
Should this have been a DPDT instead of DPST, or am I just not getting it?

Thanks, i will try to see in these shops. Problem is that evrytime i order something it calls for 50-100 $ of shipping
EEEK! I see your issue now.
I'm kind of lazy, with a really difficult work schedule, but I guess if you needed someone to ship gear to you, I'd be happy to try and help.
Looking at US Postal, overseas to Croatia, with a flat rate envelope and a 6-10 day delivery . . . Is $11.95 USD.
A first class international package with weight at 3 pounds is $23.00 USD. The weight is over rated, I figure a 1 pound package should work. A 1 pound package is $10.30USD. The issue here, is that it says delivery time "Varies". What does that mean to you and me? I don't know, maybe a week, maybe a month.
Add that to what it would take to ship any of those to me in Texas, and that might end up cheaper than supplier shipping rates. I guess the only issue would be the shipping times. the If you want to try to work this out, PM me.
I'll post a topic in the general discussion and see if anyone else has gone this route before, and see if they can give us pointers. Has anyone else used the US Mail to ship gear to guys and gals overseas before?

Yes.
When I realized that I had the wrong switch, I just temporarily hard-wired the "Auto" mode so I could at least try it out until I could buy the correct switch.

Darn it! I guess I'll just have to go to EPO tomorrow. . . While I'm there I can pick up another 1.63 ohm 3W resistor to replace the one I nuked today setting up the current meter. I guess he really meant it when he said the positive goes to the square terminal.
I can never get out of EPO without spending $100 bucks tho. . .

When setting the current meter, you need to disconnect one lead of the 1.6 ohm resistor. This is an error in the instructions. The 3W value is sized for low duty cycles during normal operation, not CW as if you were to test the meter with an external source.

If you send me your address, i'll be happy to send you a new 1.6 ohm resistor.

Dr. Shock do you have a list of errors in schematics, parts list and book?
Most of all the errors, including the 1.6 ohm error has been discussed in this thread. Please take time to read through all the comments and you'll pick up on any errors / concerns / etc...

yup as Daniel stated, you will save a lot of time and headaches if you kinda thumb through this thread. I've pretty much asked all the same questions so far.
