Is the Kenwood ts-830 still a remarkable radio?

(Author: Richard L. Measures, AG6K) The ancient TS830S is a still a remarkable radio. Processing:The processor is clean andeffective. When an 830 processor is turned on, the S- meter at the receiving end noticeably increases and the perceived volume increases – yet the audio is clean and understandable.

What are the problems with the Kenwood ts-930?

Ninety percent of the problems with the TS-930S appear to center around the transformer-based linear power supply. Many have found ways to improve it using more modern components, but those solutions fail to address the heat and sheer physical weight that it adds to the radio.

What kind of power supply does Kenwood use?

I used a high quality Phoenix Contact, industrial switching power supply, type QUINT, 24 VDC – 28,5 VDC adjustable, delivers output current 10 Amps and 15 Amps boost. Code manufacturer: 2938604, EAN code: 4017918890537 and is available worldwide.

Can a Motorola transistor be replaced on a Kenwood?

To replace the Motorola driver transistors please check your Kenwood dealer. Some series of the MRF 485 transistors do have a too high gain (hFE). I used a high quality Phoenix Contact, industrial switching power supply, type QUINT, 24 VDC – 28,5 VDC adjustable, delivers output current 10 Amps and 15 Amps boost.

What kind of resistor is on Kenwood ts-830 radio?

It seems that with the increase in the screen voltage from 210 to 300 volts, R37 on the RF unit (#X44-1360-00) heats up tremendously and will change it’s value so greatly that even the receive either suffers or goes out totally. R37 originally is Metalfilm resistor at 3.3K ohms and is 1/2 watt.

Where to put lock washer on Kenwood ts-830 radio?

Between the heat shink and PCB foil, add a toothe-lockwasher N17-1030-41 at eht two self-tapping screws on the side of the heatsink that has the two transistors attached. (The remaining screw already has a lock washer.)

Is there a replacement rl-1 for the ts-830s?

RL-1 REPLACEMENT RELAY TS-530S TS-830S A problem with this relay can cause both receive and transmit problems of an intermittent nature. Kenwood Part# S51-4401-05 was discontinued many years ago. Here is a pin-for-pin drop-in replacement that will cure that intermittent ALC and slow comeback receive you may start to experience.

What kind of switch coupler do I need for Kenwood 830 hybrid?

See INSTRUCTIONS. Will fit all hybrid models, but is especially useful to replace the breakage-prone nylon band switch coupler on the 820, 530 and 830 models. These are made for metric use, for Kenwood, Yaesu, and other Japanese brands, with 0.236″ shafts.
