Adding CTCSS to an FT290 mark 1

I had obtained a Yaesu ft290 mark 1 and wanted to fit ctcss access for repeater use.
However i wanted to make the different tones accessible easily.
The memory switch on an ft290 is a bcd switch as is the tone selection inputs on several of the ctcss modules available on auction websites (such as ebay) so it seemedas if the solution is to link the ctcs sinputs from the ctcss module to the memoryswitch (losing the memoryfacility of course but i didn't use this anyway)
I obtained a ctcss kit from ebay which had the bcd input facility for tone selection.
Usingthe ft290 schematic i fed the tone output from the ctcss module into the mike amplifier circuitry (see the schematic or speak to me)
I then disconnected the memory switch from it's existing place and reconnected it tothe bcd input on the module (anyone interested inthe finer details of the wiring please let me know).
This resulted in the tones being selectable in consecutive order on the memory switch (very handy if you use repeaters in different areas)
Anyone wanting to have a go at fitting one (and understands bcd of course) come and speak to me!

NARC Training 2019

Training is very important to us as we realise that is how new people can come into the hobby and attain their Foundation, Intermediate and Advance Amateur Radio licenses.

The Syllabus and Exams for all levels is changing significantly from August 2019 and so like many other clubs we need to take a break from running courses from August to give us time to research, prepare and plan courses based on all three levels for 2020. However we will be running three courses before August; A Foundation course in April, an Intermediate course from March - May and another Foundation course in June - July. So if you would like to take either of these exams with NARC in 2019 you need to book your place as soon as possible by emailing Exam Secretary David G7URP: This email address is being protected from spambots.
