Why to decrease the microphone level using resistors and after again to boost the signal? The S/N ratio will be forever degraded.ДЄll dividers were removed in order to increase the original level of modulation: R512(680) removed R724(4K7) bypassed R725(15K) removed (resistors values found in my radio, not same with Service Manual. Immediately i saw some resistors between microphone connector and preamplifier stage. Good results but level of modulation was affected. Feedback R721(330K) resistors was replaced by 100K. The noise was decreased enough, but also high spectrum of audio modulation was affected. I tried to apply 1nF roll off capacitor in the feedback loop. IC preamplifier is located on Front Panel PCB. After investigation, IC711 microphone preamplifier was found with poor perfomances. Background noise was higher than my GP300 monitor. Poor signal / noise ratio of TX modulation - modificationДuring testing I noticed a low signal to noise ratio for TX.

'UHF F1' screen appear for short time, after that 'Test Mode' can be accessed.Д¬heck the service manual for more details at Adjustment - page 45. Keep pressed key, in same time switch ON the radio. In order to activate the feature, R614 'zero ohm' resistor must to be deleted! This resistor is located on front panel PCB, near to CPU.ДЄfter that, the radio channels can be programmed directly by front panel keys.

Front panel programming is possible only if 'Self Programming Mode' option was previously selected by PC software (go to Edit / Option Feature and then upload to radio). Radio display when internal CPU is accessed by computer: Connect data cable and go to KPG-60D PC software at Edit / Channel Information. Channels programming procedure can be performed by PC software or using Front Panel keys. I reprogrammed the radio and for right now and it seems to be working but not sure for how long.PC Software programming for TK-880: >KPG-60D>KPG-62D version 2.00> Programming Interface KPG-46 Schematic>Service Manual rev.

Is there anyway or can someone give me some advice as why it does this or even how to fix this. Now when I go to channel 1 in group 1 and power off the radio and turn it back on it works fine. But unfortunately when I placed the radio into scan mode and power the radio off A's on the same thing happened where it just showed the Amber background light and a small scn for scan. The radio displayed everything that was programmed into the radio. I powered off the radio and turned it back on again and it worked fine.

So I rewrote the code plug and retired it again. The radio displays no text and all the radio button are disabled. When I go to power off the radio and power it back on it gives me a blank screen with just the Amber light in the background and a small p for priority. The radio accepts the code plug with no problem. I recently programmed the radio with my county's frequencies. I have a kenwood tk 880-1 uhf 450-490mhz.

Commercial, Professional Radio and Personal Radio.

We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. The benefit is you do not need multiple versions for each radio (unlike Motorola). The conventional package is more reasonable though is still several hundred dollars. The trunked package is in upwards of $2,500. One package is for conventional programming and the other for trunked programming. Often the Kenwood software is less than $100 so don't be a cheapskate just purchase it.ДЇor M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. Typically each series or individual radio requires its own software package. Please use Google or some other search engine to find a dealer that sells the software. The various other vendors often permit their dealers to sell the software online (i.e., Kenwood).
