kt6040 tuner

Post by pioneer » 16 Feb 2015 22:06

hi, just wondering if anyone has/uses the kt6040 tuner, and just how good is it, unmoded, no filter changes, just as is. the reason I ask, there is one local to me which im thinking about, so just requiring some input from you guys as to how it performs. will use it unmoded till I can find filters for it. and what is the going rate for them, this one is 20 odd quid..

Grab it quick and re-filter it at leisure! A fine dx machine even with original filters

Get it! It's very selective 'off the shelf' and the audio quality is superb.

Hopefully it comes with a remote. Not a problem if now but the tuning can wear out (as it did on mine) so tuning with the remote is almost essential, but don't let that deter you.

no idea if comes with remote, so just go for it and get it then. it will need be used as is, as no filters to mod it, unless someone knows where can purchase filters, and which ones would be best.

I will use a KT-6040 in the future. From what I've been told, it is very sensitive, and particularly sensitive on aircraft scatter, tropospheric scatter and meteor scatter, which means it would give almost daily reception of signals such as IJsselstein (HOL) and Egem (BEL) in the East of England. When modified with 80 kHz filters, the selectivity is equal to the XDR-F1HD, but the F1HD has better fidelity, and the sensitivity is probably better on the KT-6040. I will also have 110 kHz filters, which are adequate for the stronger ES and tropospheric signals, but have much better fidelity and allow full RDS. The 6040 is also very good against overload from nearby strong transmitters (in my case Tacolneston, which is 5 x 250kW), which means it has very good image rejection.
One thing I would like John Faulkner to help me with is the connection to the Conrad RDS Manager. John, could you please be so kind to tell me in detail how to connect the Conrad to the 6040? I will use the Ray Dees RDS Manager, which was designed to be a replacement for the Conrad RDS Manager, but could you please tell me how you connected the Conrad to your 6040?

Just take the audio from one channel of the KT6040 and feed it to the CRM. The signal from the phono outputs don't go through a discriminator circuit so the RDS doesn't get filtered out.

My Conrad RDS Manager was also modded, which made a big difference, and those details can be found here: http://home.pi.be/~wijnherm/

that sounds easy enough, so the 6040 does not have rds, but through Conrad rds it will then display rds, is that right. sorry for questions, I have a lot to learn. mark...

That's correct. There is no RDS display on the KT6040, hence running this little mod. The KT6050 has RDS but, as other DXers have reported, you will still benefit from having the CRM mod.

All you are doing is feeding the data and clock from the CRM to a computer's microphone input and letting RDS Spy do the decoding.

The CRM will display RDS by itself too, but RDS threshold is much, much lower via the CRM mod.

No problem Mark.

My technical knowledge is not that great, but if I can help I will. I am sure other members will be able to advise better on the more techie stuff.

ok, thanks for that. im not a technical person, far from it. been away from radio almost 20yrs now. its only the last couple yrs I have got back into it . back in the old days of band 2 I just used a car stereo, an icom ic-r700 and a small beam, not ideal, but did not know much back then. to get a few stations other than the local stuff back then was a bonus for me, if I got, which I did regularly stations about 50/70 miles from me I was happy. but times change and you learn more, and end up being where we are at today, more informed, and a bit more knowledge. looking forward to being seriously involved in band 2 dx, been a long time in coming. and thanks to this site, it has now given me ideas as to what I want. already got 2 sb920,s a st-se700, and getting a kt6040, along with the kroner antenna. enough to be getting on with at the moment. I was active on the ham bands, but that seems to be put aside in favour of band 2 now.cheers, mark...

I too prefer broadcast DX to the ham bands. I have rarely been active on 10m in the last few years, but very active on 2m, where I used to live in Nottinghamshire.
