Construction Notes & Corrections

SUPER Tuna Transmitter
Andy, M5ALA, reports that a couple of errors in the OLD documentation results in a SUPER Tuna that is not so super in operation due to low output power. Values given for C17 are actually for C18 and visa versa. Please check the current documentation and schematic in the SUPER Tuna section below to make sure your SUPER Tuna is operating as super as it can...

Sudden Storm][ & Rexwood 1000W Receiver (using a Sudden Storm][ board)
Ryan, G5CL, reports that a couple of errors in the Sudden Storm & Rexwood 1000W receiver kits. If you look carefully at the circuit board traces at C7 & C8 you might find that the traces run right through both leads of each of the capacitors. Check your boards to see if the capacitors are shorted through. If they are, cut each trace between the cap leads for significant improvement in the audio. Also, the value of C6 should be reduced to something like .033uf for increased audio levels. If you don't have the necessary cap, please let me know and I'll send you one!

The silk screen designator for LED D1 is reversed on the original run of boards. Build the board using the NIGHT Code Schematics on-line. The orientation on the LED as shown in the documentation is correct.

TUNA HELPER

The silk screen designator for TRANSISTOR Q1 is reversed on the original run of boards. These boards have no version designator, while future boards will have a version number. Install the transistor opposite from the orientation indicated on the silk screen.
