Contains technical specifications + description, parts list, construction details, principles of operation, detailed operation instructions, alignment details and block- and circuit diagrams. When the radio boots up, it shows the firmware it is running is Version 1.5111. According to the sticker on the back, the radio is, in fact, a Version 2.0, which is what I wanted. If the message is relate to an article, the article can be selected next to each message. Hi, I would like to use a Kenwood TK-730 or TK-830 radio for an AllStar node. Kenwood TK-630 / TK-730 / TK-830 manual 9 years ago 3451. I just got myself a Kenwood TK-880 unit to add to my little collection. This forum message list include all message for that is related to TM-261, this include message that also is related to articles. Please check SM diagram).įinal result: improved TX modulation, close to Motorola quality.hi.Note that page can take a while to load, if there are many modifications. Why to decrease the microphone level using resistors and after again to boost the signal? The S/N ratio will be forever degraded.Īll 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.

Discriminator 1) Set test mode Rear TX-RX L6 AF output voltage CH.

up a dmr repeater using your mmdvm repeater kit board and a kenwood TKR-850. View and Download Kenwood TK-880 service manual online. Feedback R721(330K) resistors was replaced by 100K. You must open the transceiver and use the discriminator audio for tx/rx. 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.

Unfortunately the TM-241A does not have a conventional squelch. Poor signal / noise ratio of TX modulation - modificationĭuring testing I noticed a low signal to noise ratio for TX. Typically a good place to get discriminator audio is the high end of the squelch control. "UHF F1" screen appear for short time, after that "Test Mode" can be accessed.Ĭheck the service manual for more details at Adjustment - page 45. However, by adding a jumper on the circuit board in the front section of the radio and then enabling the 'Dealer / Tuning' mode with the software during programming, they can then be. Keep pressed key, in same time switch ON the radio. The Kenwood TK760 and 760H (and TK- 762/762H, 768/768H, 860/860H, 862/862H, 868/868H) are all intended to be programmed by the dealer, using a laptop PC. 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.Īfter that, the radio channels can be programmed directly by front panel keys.
