I upgraded my Kenwood TS-590SG with TCXO and Military Look 

Yep!

Large paws.. Yes :)

Thank you! 😊

Thanks 👍

Oh - you did it too? Yes, I like :) Made a cock up of the TCXO though! Well, almost!

Yeah tnx!

Good point!

You're welcome!

Yeah.. Probably cost.

But then hobbyists wouldn't have anything to do!

Thanks for the tip!

Tnx Gary!

Nice 👍

Fingers crossed!

Yeah, well sh1t happens sometimes. Not much you can do about it.

Flux is apparently my mistake.

@@DXCommanderHQ 🙂 We're here to share knowledge, right? I've learned so much from channels like DXCommander... 👍

Flux in little hypodermic dispensers is a must😊

I've not done anything since this.. I am also terrified of opening a radio up!

Yeah, that 590 is genuinely a fab radio, often passed by by folks wanting color screens and bells and whistles. They buy those - and quickly sell them. But 590s seem to "stick".

Tnx Tim!!

Yes!

No idea when they made it. Could have been 25 years ago like my TS-2000.. But if you care, make me an offer! LOL Remember, it's a Kenwood - and it'll outlast me!

@@DXCommanderHQ I would if I didn't already have one. Mine doesn't have the voice recorder and they don't make those anymore. Serial number starting with B is 2010 onwards, the first number is the year of the decade, and the second number is the month. Thery're still making them, mine starts with the letter C for 2020 onwards....

I wanted it because further up the bands, my freq was out a whisker - I could have probably solved it another way.

Oh heck, I don't know.. My good friend owns a fancy Vape Shop and is always giving me new stuff. Right now I'm on "Drag"

Oh right on! whatever keeps you off the smokes!

WWV is not very strong in the UK at times., but there are plenty of other standard signals. (BBC Radio 4 is very closely controlled) Be careful using SSB that usually switches in a fixed frequency BFO osc, so what you end up doing is using that as the frequency reference! See Alan W2AEW video number 58 for a generic method of checking a frequency counter against a standard signal, and number 301 for this same mod to a 590 including the calibration method.

Yeah it looked like the solder didn’t have flux in it

Hey thanks. Nice to meet you!

It's small for 19 inch.

Isn't Lynch the main supplier ?

Yes ML&S.

Erm.. You may have to do a google search.. OK, I found him.. The maker is sp6gvu.. Maybe track him down on QRZ..?

@@DXCommanderHQ thank you Callum! Regards graham

Yep.. All about cost..

Or in Outlook, CTRL SHIFT F

I don't know why he would tell you that - I just can't work out why someone would think you couldn't? But anyway.. . TS-590SG will stand low voltage and performs fine. I take all my radios in the field.. I have even taken my TS-990s out /P along with my Acom 2000. You could take anything I guess.

Lead free is rubbish stuff. Fortunately you DO NOT HAVE TO USE IT. you only need to worry about that if you sell a product commercially. For home construction and such, Lead/Tin solder is fine.

@@andye2005 Here in the states it is only required for water service not electronics.

63/37 is the way.

Yes, the aftermarket ones I believe don't need my tinkering..

Yes, you can pick them up cheap. Just watch the reviews though..

I went back, sold that cramped kludgy mess of a dx10.

DX10 audio gives me listener fatigue. 101D, less so. 590SG - not one bit!

as long as you like that's all that matters :)@@2E0RME

Yes John, however no it's in, Mike M0MSN can do that for me. He's a lot cleverer than me!

Using an off air signal is fine It does not matter if the receiving RX is in calibration or not. ()you are only using it to detect a beat note) Tune to the signal in CW mode. Inject your sig-gen into the antenna on the same freq and watch for the beat once at zero beat, you sig gen is at the same freq as tyhe standard, so you can feed that into the equipment you want to test I've mentioned Alan W2AEW videos number 58 and 301 elsewhere that shows in detail how to do this.

@@andye2005 Thank you for your reply I understand what you are saying however, the point I am trying to make is that if you require accuracy then don’t calibrate to another radio as it may also be off. Also the only real benefit of fitting a TXCO is not frequency accuracy it’s frequency stability. The problem is that the specs state that the internal osc is 5ppm and opt is 0.5 ppm over -10 to 50C. I think you will find based on the ts-590sg specification / limitations and normal operating temperatures, fitting the optional TXCO will give very little noticeable difference.

@@M0XFXUK Providing we are on the same wavelength :-) If you are using a standard frequency transmission as the reference, then the RECEIVING radio does not matter as all it is doing is listening to the beat of the Standard transmission against the rig / sig gen you are calibrating. Checking against another Rx will of course just match whatever that Rx calibration is.

Freq standards.. Couldn't find any no.

​@@DXCommanderHQ Sadly, this WIkipedia article: en.wikipedia.org/wiki/Standard_frequency_and_time_signal_service ; isn't clear about whether the time stations also have atomic control of the carrier. That's certainly true for WWV. One would hope that other stations transmitting on the same frequencies would be scrupulous about assuring a zero beat with WWV, probably using atomic, or my likely, GPS disciplined oscillator (GDO) control. My guess is that if you can hear a time station on 2.5, 5, 10, 15, 20, or 25 MHz, that it's good enough to calibrating your TCXO (temperature compensated crystal oscillator). The Finland station at 25 MHz might be a good bet for you, but you also have Rome and Cadiz. If you hear one, you could dot your eyes and cross your Tees by seeing if they have a web site to check whether they think their carrier is precise. They probably at least use an OCXO (oven compensated crystal oscillator) and calibrate it regularly, maybe through a GDO circuit.. DCF77 from Germany probably has good ground wave to you, but I'm not sure whether 77.5 kHz works for your radio. They do use an atomic standard. The self setting "atomic" (bedside, wall) clocks in Europe probably use it. I keep wanting to build a GDO (GPS receivers are cheap) as a fun project (the commercial ones are too expensive). But here in the US I can always hear more than one of the WWV frequencies. so motivation is hard to come by. I assume that RSGB has technical aid contact points, as the ARRL lab does for me. You might ask about stations in Brittan usable as frequency standards. US analog TV video sub carriers used to be accurate. BBC foreign service stations are a possibility that you could contact the station's engineering department about. They may or may not have high accuracy carrier frequencies. And if you do figure out what you can rely on over their, that could be a worthwhile channel video, 73, Bill - KE1G

It's quite a heavy rig anyway..

Great video, rig looks good, whereabouts are the handles available? Cheers

Stability.

Well I'm not actually wrong.. The very detailed report I read had some TX issues..

@@DXCommanderHQ I have seen you soldering. I never needed soldering for the Chinese TCXO. Maybe you had a bad one, it worked for me. But still, there isn't much use for it as the Kenwoods are stable on their own. Even with WSPR, I have not seen them drift much, if at all. Most of the receivers at the other and drifted a lot. And the TXCO didn't make a difference there. I'm sorry, I can not confirm your statement.

HAHA

Well.. It's on frequency now :)

Err....no 😀

HAHAHA TOM!!!

Thanks!
