Circuit Domain now offers:
1. Razor Radios PLL adapter board (RR 719->106 V1.5) to replace 8719/8734 PLL chips to offer up to 511 channels. This adapter board only works on MB8719, MB8734 and RCI8719 radios. It is an additional $50. To convert from 128 channels to full 511 channel range (quadruple the possible range) just select this option from the "Razor Radio PLL adapter" section.
2. Razor Radios PLL adapter board (RR 824->106 V1.1) to replace uPD2824 PLL chip to offer up to 511 channels. This adapter board only works on uPD2824 radios. It is an additional $55. To convert from 40 channels to full 511 channel range (over 12 times more channels) just select this option from the "Razor Radio PLL adapter" section.
NOTE: Actual range of your radio depends on radio model and broad banding performed.
I also have BLUE and GREEN LED displays . HURRY!!, Don't miss out !!!!
This price is for "All binary and BCD PLL V2.5" KIT
New features in V2.5 DigiMax Lite:
1. Split TX/RX frequency – You can transmit on one channel and receive on another. Channel gap is configurable through the menu. It gives you a semi-private conversation.
2. Auto Range detect – on most radios the VCO drops out way before 512 channels are achieved. This function will automatically detect the actual usable range of the radio by monitoring LD pin on PLL and set the Maximum usable channel and Minimum usable channel.
3. Faster scan through frequencies.
4. Full support for up to 512 channels.
DigiMax Lite is the ULTIMATE in channel expansion for PLL02A, MB8719, uPD861, MC145106, SM5104 and uPD858 CB radios.
FORGET the band select switch!! FORGET 10kc offset rubbish!!! 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 512 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, SM5104CB and uPD858 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 few 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 rubbish, NO HOLES IN YOUR RADIO
for extra switches!!!).
Displays minus for negative channels!!!! Displays auxiliary channels denoted by A!!!!!!
DigiMax Lite channel expansion mod is UNIVERSAL, designed to expand coverage of CB Radios for educational purposes.
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 assembly.
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.
6.7cm Long x 4.7cm Wide x 1.5cm High
LED 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 different 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 accommodate 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.
Due to the unique design of the display circuit it supports Cobra 2000 and Washington
style radios where the channel display is mounted beside the channel selector.
1. 512 CHANNELS - V2.5x of DigiMax Lite supports 512 channels (MB8719 is 7bit so only 128 channels) the coverage depends on your radio model.
2. FLEXIBLE - Supports many radios with binary or BCD nCode (most popular PLL02A radios), MB8719, MC145106, uPD858 (non-ROM locked) etc.
3. ALL IN ONE SOLUTION - Works with AM and SSB radios.
4. INTELLIGENT - Automatically works out the 9-bit channel range (Minimum and Maximum channel) for your radio.
5. EASY INSTALLATION - Only solder few 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 -199 through to channel 508 (the coverage depends on your radio model).
8. SCAN CHANNELS - Much like a scanner does, once activity on channel is detected the radio stops scanning.
9. HIDDEN CHANNEL DISPLAY - All Auxiliary channels are displayed as 3A, 7A, 11A, 15A and 19A.
10. QUICK JUMP TO YOUR CUSTOM CHANNEL - From any channel (negative or positive) just press the channel selector switch once and you're there in a flash.
11. SUPER FAST INSTALL - Replaces your current channel selector and display assemblies (only solder few wires to get extreme coverage).
12. 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.
13. EASY FUTURE UPGRADES - Just replace the Firmware chip. Upgrades will be available from my Shop, no need to Purchase the whole circuit.
