1.8, 3.5, 18, 21, 24 and 28 mHz bands work normally, receive and transmit.
7 mHz receiver noise but no signals, no transmit. 10 and 14 Mhz no receive, no transmit, no readout except for the last digit which changes with tuning knob. 18 to 28 mHz normal in all respects.
When last used transceiver worked normally but it has lain in the shack unused for at least two years.

- It is a Ham transceiver Kenwood TS430S. The faults are as I stated:No transmit or receive and no digital readout on 10 and 14 mHz, Receiver noise but no receive of signals and no transmit on 7 mHz. The other bands all operate normally transmit and receive. It seems to me there is more than one fault but this I don't really know.

- Of course it will handle those bands!!! This expert is wrong! I have operated ham radio for 55 years and know the ham bands very well.The 10, 18 and 24 mHz bands are the WARC bands and hams have had them for many years, over 30 years. The others are normal amateur bands that I have operated for 55 years. Wrong advice this time for certain!

- Sorry but location and antenna have nothing to do with the problem. I have been a ham for 54 years and am well acquainted with antenna and location problems. This is an internal electrical fault in this rig. The microprocessor seems to be soldered onto the PCB and can't be removed without a great deal of trouble .so I doubt whether that is the problem either.

- No dust. The unit is clean. Change of location is no fix either (unit has outdoor antennae, beam and wire dipole, both of which work on the other bands). The unit will operate without the mic. plugged in. The microprocessor must be OK as the rig works fine on most bands, only the three from 7 to 14 mHz have the problem. Your suggestions are not the solution. Sorry!

Apr 01, 2009

- Sorry but you have not the solution. The unit will operate without the mic. plugged in. It operates on CW which does not need a mic. Location and antenna is not a problem. I can't see why location would have anything to do with the problem. The unit is clean - no dust. The microprocessor must be working OK as most of the bands do not show the problem.

- The last advice was of no help. Sorry. The fault remains. Kenwood Ham transceiver TS430S. Normal operation on all bands except 7, 10.5,and 14 mHz. No send or receive on those bands and no digital readout except for one figure. No antenna or microphone problems as suggested, no location problems and yes! I am permittd to work on those frequencies.

- That is quite obvious my friend but where?

its the problem of the frequency range its getting blocked  at particular location.these can be solved by two options 1)first try changing the location of the unit from one corner to another corner.that should help to catch the frequency again if its getting blocked at particular location.this happens many times.but if changing the locan does not make any difference.then  2) get checked that the antenna of the unit is not catching the required frequency for the unit.so change the antenna also connect this external antenna  as mentioned 50 ω (it comes wioth SMA Connector) that helps in catchinf the frequency. you will get this at radio shack website. this will help. ----------------------------- also in the unit there is a component which controls the frequency called microprocessor if that goes weak the unit slowly slowly stops receving the accurate signals and only the noise comes.so the micro processor in located internally in the left side.its a green and black colour mini chip circuit board.many times opening the unit and removing and cleaning the microprocessor and refitting it solves the problem but this is 50 --- 50 chance. this all has to be checked what mentioned. thank you for using fixya.

I don't believe it can really handle those bands. Seems like most ham have problems with those frequencies. do you know someone else with a ham who could check for you/

Have you tried and blow all of the dust out of it.Thats what it sounds like Or where you have the mic plugged in or what ever else is plugged it is a dirty or corroded.hope this helps you.

- One more thing to add is your mic plug clean to or pushed in all of the way.I know you know your stuff which you have indicated but we all seem to over look things and just want to make sure everything is clean and plugged in tight before we move to the inside..
