A PICAXE-14M2 BASED CW PRACTICE BOARD

This board will key out Morse to a 2N7000 and a small speaker depending on the selection of the 4 DIP switches. See the photos below.


DIP SWITCH SETTINGS

OFF = 0, ON = 1
DIP switch settings   SW#1 = 1,  SW#2 = 2, SW#3 = 4, SW#4 = 8
Just add the decimal equivalents. ie. All switches off = 0. All on = 15

0] Sends random A, E, I, M, N, and T in groups of five.
1] Sends random D, G, K, O, R, S, U and W in groups of five.
2] Sends random B, C, F, H, J, L, P, Q, V, X, Y and Z in groups five.
3] Sends random Letters in groups of 5.
4] Sends random Numbers in groups of 5.
5] Sends random simple Punctuation in groups of 5.
6] Sends random Letters and Numbers in groups of 5.
7] Sends random Numbers and simple Punctuation in groups of 5.
8] Sends random Letters, Numbers and simple Punctuation in groups of 5.
9] Sends random VK 2x2 and 2x3 call signs.
10] Sends random ZL 2x2 and 2x3 call signs.
11] Sends random J 2x2 and 2x3 call signs.
12] Sends random A, K, N and W 1x2, 2x1, 1x3, 2x2 and 2x3 call signs.
13] Sends random AA0AA to ZZ9ZZ and AA0AAA to ZZ9ZZZ call signs.
14] Sends a few random radio words (QRT, QSL, rig, ant etc. etc.)
15] Sends a few random words (to, the, when, there, here etc. etc.)

If constructing, the circuit board is exactly 60mm x 80mm. *** Remember*** Try to use what is known as "presentation paper" for the toner art work transfer.

I found it in the US while on holidays in a 250 sheet ream.  It's A4 and glossy on both sides. Very very light weight at 120gsm and looks like glossy magazine paper.

216mm x 279mm (8.5" x 11") and made by Hewlett-Packard, Product No. CG988A. I would think other companies make "presentation paper". And remember,

NO peeling the presentation paper off the copper. Let it soak in the hot water and float off the copper.
