Thanks DTB! I've been on a break from CBduino simply because I'm using my free time to study to upgrade to a General ham ticket (just recently got my Tech license). Why drop scan? Couldn't both memory channels and scan be implemented? It's been a long time since I pc programmed, but I was...

My board has the RCI8719 and the Galaxy 959 schematic shows external 1k pull down resistors between the PLL lines and ground. On my board those resistors are unpopulated, though if you install them it indeed pulls the PLL lines low. If the pull downs are not installed on my board and nothing...

This sketch reads the channel selector on my 979 through a 9555 i/o expander and outputs to the pll through a level shifter. It starts at the lowest possible channel and works it way up 40 channels in sequential order with no skips or channel misalignments (26.815 to 27.205 on my radio)...

Playing with interfacing to the channel selector. It seems the PLL in my radio is pulled high and then connected to ground by the channel selector to pull a line low. This is confirmed by the radio being at 27.445 if the PLL lines are unhooked, which does equate to all high in binary, and if I...

I thought about one earlier, but it was for another project. I ordered one but when it got here from China it was DOA and not worth returning, so I used an lcd on the project and went on. The Yahoo Groups member has prompted me to get another coming though, I ordered from upgradeindustries as...

Have you thought about OLED? One of the guys on the Yahoo group has found a .96 OLED, about $10 off fleaBay, fits nicely into a CB channel display window. The library takes up about a third of the program space, but it could probably be streamlined and your sketch is small anyway, no need to...

Yep, I LIKE this version of the sketch! It's using up some variable storage though. Currently that's not a big deal, but if you're going to add in 300+ channels it could be. 8-D I think there's a way to store an array in program storage, just gotta take the time to dig that up.

channel = map(pot_val, 0, 1023, 0, 127); WOW! That map function is pretty slick! Thanks C2!!!

I get by with a little help from my friends... This version is significantly smaller in program size, though the variable storage has increased. It was known in earlier versions that using a loop to handle the channel lookup would be quicker, it didn't allow for channel numbering that...

I was working on a digital readout for a hydraulic press used in making high power model rocket motors when it hit me. Here's one, of many, threads on the net about it: http://forum.arduino.cc/index.php?topic=83079.0

Hi TM86, I'll take a look...at first glance we could: Use the channel selector, once all forty slots in a particular band have been ran through then change a band flag in the eeprom. Have a forty slot array for each band, switch arrays based on the band flag. Though the PLL is capable of 128...

Hi C2, Attached is a PDF with the parts, hookup info and a couple pics. The level shifter has 500K pull downs in it, 5-10k is usually used, the 959 uses 1k, but so far it's been stable just using the internal ones in the level shifter. I've only been testing using an a/c supply and not much...

CBduino Lite V1_0 This version of CBduino has the lcd display routines removed so you'll need a radio with a frequency counter (internal or external). It simply reads a 10K pot and adjusts the PLL settings from the lowest to the highest. This isn't radio specific, any radio with a 8719 will...

Wow! I'm surprised at that, it seems like a nice group of guys and they don't seem that picky on membership....they let me in! 8-) I would try again, if you're denied again lemme know and I'll speak to a Moderator, there are two I know of that active and very interested in the 'duino (and...

I will, I'll put the more stable releases here along with an explanation of the what, how and why. I'm working on commenting the code too.

Hi Mechanic, we're plodding forward...not much activity here, but I also posted on a yahoo group called "The Mod", it was a group dedicated to the Farmer Dave freq mod, but the kits are no longer being offered and Farmer Dave has disappeared. There's been a fair amount of discussion and...

The problem isn't really the 8719, it's more about the frequency supplied to the pll and the channel skips/arrangement of the original 23 channels. hotrod, I just haven't taken the time to figure out reading the channel selector, but if you don't mind mounting a 10K potentiometer and 4x20 lcd...

If you want to experiment, we could probably get an Arduino to do this for you.

Please don't take offense, none was intended, I was just thinking out loud. The synthesizer board you linked to is interesting, and I have one on the way, but for what I'm doing right now I don't think it's really necessary. I have a Temp One I've recently repaired and have been using to...

Taking a look at the digital replacement option for the crystals... First I'm wondering if there is a pressing need to be able to do less than 10kc resolution? Most radios operating in the 26 and 27 mhz bands are converted CBs aren't they? (I'm sure there are ham setups operating in this band...
