<\/a><\/div>\n

I’ve been getting tired of being in the dark about the frequency on which my BITX17 was operating. So I pulled out some graph paper, my frequency counter, and a pencil. You will see two frequencies at each point — that’s because I use two crystals, switched by the black knob on the left. I realize this paper and pencil approach is hopelessly out of date, but I see it as “appropriate technology” for a discrete component all-analog transceiver. <\/b>

<\/b> Pete set me straight on how to come up with the numbers: VXO frequency minus ACTUAL carrier oscillator\/BFO freq. After doing this I took great delight in going on the air and asking guys with fancy “glowing numerals” rigs to compare their freq readout with my pencil and graph paper readouts: they were painfully close. <\/b>

<\/b> But I am not slipping completely into stubborn Luddite-ism; this weekend I worked on a DDS-based AD9850\/Arduino VFO with I-Q output based on Paul M0XPD’s Kanga-UK Arduino Shield. STAY TUNED! <\/b><\/p>\n
