![]() "COLIN LAMB" wrote in message ... Hello Miken: I If you are going to use integrated circuits in a glowbug receiver, you need to hide them, since it is unbecoming and might cause others to ridicule the otherwise heroic effort to recreate a glorious radio. A simple tube can do a wonderful job of putting out 100 kHz signals, and if you want 50 kHz, you can use a neon bulb divider. Many of the simple receivers I built would have been lost with a 100 kHz marker. A 1 MHz marker would have been more useful, and even then I was guessing at the which MHz it was. The best marker was simply a crystal in the ham band and a known point. Something like 3550 kHz, which could also be used to spot at 7100 kHz. Even odd marked frequencies are useful - then a properly hand calibrated graph laminated on the front panel (ala HRO) will give a feeling that none of the wonderful new rigs can touch. 73, Colin K7FM Colin do you have a link for using a neon lamp as a frequency divider? This is the first reference I've seen for this, and I'm fascinated to learn more about it. Peter |
