Cobra 200 GTL DX Repair Part 1 

Hi and thanks for your comment. Yes I was a tough radio to get going again. I am glad you enjoyed the series it was fun making it too. I am going to make one last video of this radio carrying out a full alignment before I ship it back to Ireland I’m just waiting for some trimmers to arrive from Digikey. Best regards from the other side of the pond.

I just Subscribed. Looking forward to the final completion. John where exactly are you located? Best to you again.

@@SFLightfoot Thank you for subscribing to the channel. I am located a place called Alvaston Derbyshire within the United Kingdom. I used to live in North London but I move up here around a year ago I think I need update my QRZ page.

Thank you for your comment, It’s good to be back in action as you can imagine I do enjoy doing this kind of stuff and I will try to make more videos. Best regards

Thanks Alan I am glad you found the video of interest and just to let you know we have now managed to find a replacement coil and as soon as it gets here I will make part 2. Very best regards

Hi Gary it's a pleasure to hear from you as always and I hope all is well with you and yours. Glad to hear the 2955 is holding up. Re the R&S unit it was a unit I picked up as non working and managed to get it going again you know me LOL ;-D. Best Regards

Absolutly agree

Hi Dave Thank you for your generous offer as it is really appreciated. Within an hour of releasing the video we managed to locate a coil and it’s on its way. Thanks again

@@M0XFXUK that's good, Thanks Dave

Hi Andrew, thanks for the comment it’s great to hear from down under. I’m using a SONY A6400 mostly using the stock lens filming in 4K. It took me a while to figure out how to set it up but I find it works quite well.

@@M0XFXUK ps , i watched all 4 ofmyour dx200 viseos, they were top notch!!BRAVOS

Hi, sorry for the delay getting back to you. To be honest I am not really an expert with these radios and don't have one to take look at, however if it showing all 8's in the display I would guess that the PLL is not locking up which could be caused by a number of things. You can test the PLL lock voltage with a multimeter at test point 1 as outlined in the service manual alignment section. You should be see 0,2 to 7 VDC. I hope this is of help.

Hola Gabe, estoy ubicado en el Reino Unido y la distancia para enviarme la radio es demasiado grande. Lo siento, pero no puedo reparar su Cobra 2000 GTL-DX.

Yes I agree the parts used in these radios are rather odd as a lot of the parts seem to be made by KEC and they also appear to be copies of obsolete Toshiba and Matushita components. I am managing to work out some equivalents however I have not had any luck finding coils though. Thanks for your comment. Best Regards

Hi Chris, I am in Derbyshire in the UK.

You will have to show me the counter issue so we can take a look at it.

@@M0XFXUK would love to, I believe it's a common issue with the design of the radio and not sure if it can be rectified.
