(QRT for know due to an audio issue) Watertown repeater (W4LYR) 443.575+ PL 107.2 (not TSQL). Watertown repeater (W4LYR) 146.835- with a PL tone 100 NOTE:PL is not TSQL, the repeater receives a tone, but dose not transmit one. Nashville WA4RCW repeater (former metro PD repeater): 442.750+ of 5 hertz with a pl tone of 100 Go to for up to date information on the mtears statewide system The 67 also holds the Davidson County traffic net at 9pm on Sunday evening. All of these repeaters are up and running.ĪF4TZ nets: Information net on the 147.015 7:30pm on Monday evenings. The 147.015 repeater has a positive offset and the 444.150 has a positive offset as well. The 146 repeaters have a negative offset and pl-tones of 114.8. They hold a information net every Tuesday evening at 7:00pmġ46.64, 146,67, 147.015, 444,150 are all the AF4TZ repeaters in Nashville TN. This one is on Short Mountain as well, and is utilized by the Dekalb/Cannon county club. They also hold an information net on Tuesday evening at 8pm, as well as a traders net Thursday evening at 8:00.ġ45.490- no tone. Short Mountain Repeater nets: The famous “Old Codgers Net” Monday evening at 8:00pm. Short mountain 91 (W4YXA) (run by the Short Mountain repeater club, Cannon county, TN) 146.910- no tone ( ) Sumner county nets: Sumner ARES information and training net. **Normal operation is for Mockingbird Hill Repeater to be unlinked from other system** Mockingbird Hill (Gallatin, TN.) (Off air temporarily) 92 Watts NOTE: This repeater is intermittent due to an issue with the machine. Sumner county ARC (W4LKZ) Linked Repeater System Music Mountain (5 miles North of Gallatin, TN) Wilson county TN repeater: (WC4AR) 147.105+ and an occasional pl tone 100 (when interference makes it necessary) NETS: Wilson ARC and ARES information net, 7:00pm on Thursday evening. If you find inaccuracies please email me at There are instructions on adding you repeater/net at the bottom of this page. Rather that making it huge, we are striving to make it 110% accurate. This is our ever growing list of middle TN repeaters. Please check SM diagram).įinal result: improved TX modulation, close to Motorola quality.hi.We all enjoy some good VHF/UHF rag chewing, so there is a good chance you will find us on one of the repeaters below. 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. 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 - modificationĭuring testing I noticed a low signal to noise ratio for TX.
#HOW OT USE PL TONE IN KENWOOD TK 880. MANUAL#
"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. 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.Īfter that, the radio channels can be programmed directly by front panel keys.
#HOW OT USE PL TONE IN KENWOOD TK 880. SOFTWARE#
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. PC Software programming for TK-880: >KPG-60D>KPG-62D version 2.00> Programming Interface KPG-46 Schematic>Service Manual rev.
