Problem With Ts-830 Tx Relay; No Operation On Warc Bands - Kenwood TS-830 Survival Manual

Answer 1: Have you tried it as is yet? Generally the problem is with a hi-z microphone when
driving a low-z input. You have the opposite condition so it will probably be fine. You'll just
want to check that your frequency response, modulation and fidelity is ok on the air. (K5DVW)
Answer 2: As noted, the combination of a high impedance mike and a low impedance input
often causes problems. The mike thinks its output is shorted, and does not work well. (A well
shielded audio transformer, or any of the cheap kit preamps around will do a fine job of
matching everything so it works.)
USUALLY any problems caused by a low impedance mike and a high impedance input can be
solved with a resistor across the mike terminals in the plug. The mike sees an acceptable load,
the amp doesn't care as long as it has some voltage to amplify. If you have problems try
something on the order of 470 Ohms to 1 kOhm - it should work fine. Although you may have
to turn the mike gain up a tad. (Pete AC5E)

Problem with TS-830 TX relay

Question: the TX relay "chatters" on all modes including tune. The relay chatters during
transmit only. The receive seems fine. (Terry N8CDN)
Answer: The relay is in a socket that is in the inverted position and after many years of use it
can work it's way out of the socket. I used to work a lot of AMTOR and my relay fell out of the
socket one day! The relay might be loose in the socket with a poor connection on the transmit
side. Simply open the TS-830S up, find the relay and go ahead and completely remove it.
Inspect the terminals for the dreaded green stuff and if it's there clean it off. Replace the relay
and check operation. (N4ZOU)

No operation on WARC bands

Question: Transmits fine on all bands, except 18 MHz and 24 MHz, where I get absolutely 0
power out. Does anyone know if this radio needs to be modified or have something special done
to work in those bands, or know where I should go from here? (Jeff WO5D)
Answer 1: The earlier TS-830's had to be modified for WARC (30 m, 17 m, 12 m) TX. (Mark
K9MQ)
Answer 2: I have a TS-830S and had a similar problem. My radio had no output on 30 meters.
It was because the band selector switch was out of adjustment. (Dave W8DEP)
Answer 3: There is a wire under the chassis that you have to clip, then the WARC bands will be
activated. I have a copy of the manual, if you'd like I could scan that page from the manual and
e-mail it to you. I think you're going to like your '830. I've had one since 1987 and I still think it
has the best receiver I've ever heard.(Steve K0SR)
Answer 4: The wire probably needs to be cut. These rigs were manufactured before the WARC
bands were officially opened. This way Kenwood could still manufacture them without
violating FCC regulations. By the way, you are very very lucky to find a rig that hasn't yet been
modified. Probably, it doesn't have a lot of operating hours on it. I also agree it has one of the
best receivers ever built. I often think about getting a newer rig, but that would mean I would
probably put the 830S on the shelf and forget about it. I like it too much to do that, so the new
rig will just have to wait. (Bob N2WSO)
