OK, not sure I totally understood the last statement but will make general assumptions and work-arounds

I appreciate your input allot so don't disappear on me or I should say us. It sounds as if you have something to offer the group. First off I see I will have to review all the concepts of dynamic ratio again so that I can follow you. Of course I'm a fan of Tentec and so will definitely take a look at your links. I'm not sittin' up here pretending to know everything about radio. I'm just speaking from my own experience. Interesting schemes you propose still, the one 1KHz thing. It bothers me. Yes I like high performance. I'm an even bigger fan of Kenwood and in the older days I would say Drake was probably one if not the best. Maybe where I confuse you is I like high performance, low cost & low power. The best of all worlds for what is practical or doable.

ei the ultimate....Hand crank high selectivity digital tune.

huh? huh? That would sell with the right price tag. What do ya think?

 

Ok Peter. I see what you got there. Yeah those are the cream of the crop. They do some amazing stuff with DSP these days. I am only interested in the bottom line. How well does it work? Just by looking at them I am sure they work quite well. I bet the price tag makes them work even better.

I suppose my objective is more toward the portable line. I mean we have yet to see 40 meter walkie-talkies. Why? Can you imagine how effective they would be? A good relay network and you don't need anything else.

 

Well I got me a loop built over the weekend. Tomorrow I should have some time to start programming and testing it. I even put in a SIP socket for on board programming.

 

2.5 mhz to 40mhz to 400mhz ? that is the question.

 

40Mhz is what I'm using right now.

 

Sir,
I read your explanations about Digital Frequency Control.This is wonderful explanation. Then how to control digital meters.

Oh why thank you. I told what I know. Digital meters are quite different. They use what is known as D to A and A to D converters. Essentially you will clock a D to A converter and use a comparator to test the voltage. Now days a processor will use a look-up table to give the voltage output though it is possible to do it without a processor by using the same counter output to be read on a 7 segment display. Much simpler with a processor.
