DigiMax Lite

BEHOLD, THE ULTIMATE UNIVERSAL MOD HAS ARRIVED!!!!

DigiMax Lite is the ULTIMATE in channel expansion for PLL02A, MB8719, uPD861, MC145106 and SM5104 CB radios. FORGET the band select switch!! FORGET 10kc offset crap!!! What the hell!!! You shouldn't have to remember to switch to Band B go to channel 3 flick the 10kc offset switch and then calculate what channel you're actually on!!!!!! FORGET the so called 96, 120, 180 or 192 channel mods (they have holes in coverage, 5 missing channels per each band!!!!) On 180 channel mod this will add up to 25 missing channels!!!!!!!! This MOD gives you RAW 256 CHANNELS!!!!!!!!! (MB8719 uses 7bit so you can only get 128 channels, if you have MB8734 or RIC8719 then you need to swap it for MB8719). FORGET mods that are specific to particular radio model!!!!! This will cover all radio models with PLL02A, MB8719, uPD861, MC145106 and SM5104CB PLL chips. If you sell your radio and get another one with one of those chips then you simply move the mod to it, NO NEED TO BUY ANOTHER RADIO SPECIFIC MOD!!!!!! FORGET complicated installation and programming, solder only 10 wires and it's done!!!!!!! Few turns of channel selector will marry the radio and the MOD. DigiMax Lite gives you CONTINUOUS COVERAGE for all bands supported by your radio (NO BAND SWITCH and 10kc CRAP, NO HOLES IN YOUR RADIO for extra switches!!!) . Displays minus for negative channels!!!! Displays hidden channels denoted by A!!!!!!

DigiMax Lite channel expansion mod is UNIVERSAL, designed to expand coverage of CB Radios for educational purposes. Transmitting on out-of-band frequencies is illegal!!!! This circuit is a smaller version of DigiMax project. This project is designed to be easily installed and configured for a particular radio model without changing the way the radio looks. At first glance you can't tell that the radio has been modified. To program the mod to your radio requires only few turns of selector switch. Once set, the configuration is saved and need not be performed again. The mod is designed to offer continuous coverage of channels from negative to positive including A channels. This mod replaces the radio's channel selector and display assemblies.

Meassurements:
Main PCB: 6cm Long x 4.5cm Wide x 1.5cm High
Display PCB: 4.5cm Long x 2.9cm Wide (with snap off at 1.8cm from top of Display PCB) x 2cm mounting depth (from face of LED to back of IDC connector)

Even though this mod has been designed to fit 99% of diferent radio models out there in the market, there are some models that it will not fit. Radios that have frequency display mounted on same PCB as the 2 digit channel display will not accomodate DigiMax Lite( Galaxy DX 959, Cobra 200 DX, etc.)
Some radios are more fiddly than others (Cobra 2000, Washington etc.), please examine your radio to see how much work is involved before you buy it.
If you are unsure please send me an email and I will let you know if you can fit DigiMax Lite in your radio.

Progress Update

It has recently come to my attention that there are people out there in different forums deliberately misleading unsuspecting users and trying to discredit DigiMax Lite. They are saying it is a copy of another design from US. This is not true to say the least.
I can assure you DigiMax Lite is not a copy of any product floating around on the internet, it has been designed and programmed from scratch. DigiMax Lite doesn't even look anything like the US backyard prototype (I'm not even sure why they are claiming the rights that it is a copy???). It is obvious these people have no idea of what they are talking about and should not be taken seriously.
However this also proves to me that they see DigiMax Lite is a real threat to the US backyard prototype, otherwise they would not try so hard to discredit it.
It is not my intention to discredit any product that may be in direct competition with DigiMax Lite (the more competition the better for the end user I say), this is why I have left out the names.
I could also claim that US based bunch have copied my design by using an encoder in their latest attempt just to keep up with the rest of the world but I won't as there are other designs out there that have used this for a while.
The US made prototype pride themself in keeping their customers in stone age for the last 20 years by providing a design that made you drill holes in your radio for additional switches just to give you full coverage. Only recently they released a design with an encoder in response to all the other designs that have been light years ahead of them for a long while.
There are real concerns about quality of any product which is backyard brewed, namely how long it will last before it deteriorates. Any home brew PCB is not a product, isolation routing and non-commercially made PCBs will deteriorate quiet quickly, the copper tracks will oxidize (rust) turning gray and green and develop cracks. So what are you paying for? The answer is: An inferior thing (I still can't call it a product).
There is no patent on "The idea to expand channels in a radio".
After all I am just another electronics enthusiast that enjoys creating and helping others.

06-5-11 - I will be offering 10% discount on new V1.2 release of firmware (coming soon) to anyone who will send me few photos of their radio with DigiMax and a quick note about your experience with installing it in your radio, (this is your say) to be posted in my Galery. All those interested please send me an EMAIL.
05-5-11 - I have received and tested samples of new BLUE displays. There are only 9 of them and they are available for sale with my kit. I have ordered 50 more and they should be here in few weeks.
30-4-11 - WOW, only few kits left from original stock... Hurry, Don't miss out.
31-8-10 - Due to vast popularity of DigiMax Lite I have been inundated with orders. Thank you for your support.
20-8-10 - Finished coding firmware V1.1. This version has support for all types of binary PLLs (BCD PLLs are not yet supported). There are additional menu functions to accomodate different PLL chips.
27-7-10 - Finished coding and debugging for MB8719, uPD861, MC145106 and SM5104.
26-7-10 - I am looking for re-sellers, please CONTACT ME if you are interested in selling DigiMax Lite.
13-7-10 - I have successfully installed my very first prototype in an 02A radio!!!! Took all of 5 minutes to solder the wires in. Works like a dream, no issues at all!!! The radio needs to be tuned to allow for additional bandwidth.

Schematic Diagram

The circuit uses a PIC microcontroller to generate nCodes for the radio. Currently it only supports binary PLLs. You can continuasly increment and decrement channels using the quadrature channel selector switch. "A" channels will be displayed as such eg. 3A, 7A, 11A etc. It uses a common cathode triple digit display but can be modified to use 3 x 7-Segment digits by means of a simple adaptor PCB. The mod uses the radio's internal 12V power.
Digimax Lite V1.1 currently works on any PLL (eg. MB8719, PLL02A radios) with binary nCode. It is designed to automaticaly detect 8-bit channel range of the radio.
Curently the mod uses lower 8 bits of the PLL binary nCode and is hardcoded to a minimum channel of -99 (we only have 3 digits to display, one digit is used for "-" sign) through to maximum channel of the radio using lower 8bits.

For example on PLL02A, if your channel 1 nCode equals to 330 (10-bit) then nCode for 8-bit is 74. This will give you a maximum channel of 70 (8-bit nCode = 0) at which time the channels will wrap arround back to -99.
If your channel 1 nCode equals to 255 (10-bit) then nCode for 8-bit is also 255. This will give you a maximum channel of 251 (8-bit nCode = 0) at which time the channels will wrap around back to 1.

To program DigiMax Lite to your radio please follow the bellow easy steps:

1. Press and HOLD the channel selector switch (about 5 sec) until it displays --- or PLL last 3 digits (---, 02A, 719, 106).
2. Rotate channel selector switch to display last 3 digits of your PLL chip number in your radio (PLL02A, MB8719 or MC145106 and others).
3. Press channel selector once to save and move on, the display will show current nCode for channel 1. In this view all dots are lit for easy identification.
4. Rotate channel selector switch to display 8-bit nCode for channel 1 of your radio.
5. Once correct 8-bit nCode is displayed press and HOLD the channel selector switch (about 5 sec) until displays channel 1. That's it.

The mod is now set up for your radio. The mod had also automatically worked out your radio's Minimum and Maximum channel.
I have also included a quick jump to channel 11 from any other channel. You can do this simply by pressing the channel selector switch once.

Benefits

1. 256 CHANNELS - V1.1 of DigiMax Lite supports 256 channels (MB8719 is 7bit so only 128 channels) ranging from Low-Low-Low-Low 24.855MHz to High-High-High--High-High 29.515MHz (the coverage depends on your radio model).
2. FLEXIBLE - Supports many radios with binary nCode (most popular PLL02A radios), MB8719, MC145106 etc.
3. ALL IN ONE SOLUTION - Works with AM and SSB radios.
4. INTELIGENT - Automatically works out the 8-bit channel range (Minimum and Maximum channel) for your radio.
5. EASY INSTALLATION - Only solder 10 wires.
6. EASY CONFIGURATION - All you need is an nCode (decimal value) for channel 1 and couple of turns of the channel selector.
7. CONTINUOUS COVERAGE - From channel -99 through to channel 251 (the coverage depends on your radio model).
8. HIDDEN CHANNEL DISPLAY - All half channels are displayed as 3A, 7A, 11A, 15A and 19A.
9. QUICK JUMP TO CHANNEL 11 - From any channel (negative or positive) just press the channel selector switch once and you're there in a flash.
10. SUPER FAST INSTALL - Replaces your current channel selector and display (only solder 10 wires to get extreme coverage).
11. COBRA 2000 AND WASHINGTON - Supports Washington and Cobra 2000 style radios with unique Display design. Simply snap display PCB in half (along perforated line) and you can mount LED display anywhere.
12. EASY FUTURE UPGRADES - Just replace the Firmware chip. Upgrades are available from my Shop, no need to Purchase the whole circuit.

Future Improvements

1. Make DigiMax Lite fully compatible with uPD858 PLL
2. Use single digit to denote negative channels ( "-1") above -99 expanding negative channels from -99 to -199.
3. Expand channel range by using 9-bit nCodes (512 channels).
4. Make DigiMax Lite compatible with PLLs that use BCD nCodes.
5. Add User Custom Min and Max channel in to config menu. Because DigiMax Lite covers 256 channels, most radios will not cover such a broad band.

Circuit Board
