    Thank you for that test Neil, thats very good of you...I'm not sure if its reassuring or not considering I was only using SSB voice rather than your 100% FT8.

    When I took the top cover off the radio some weeks ago I notice an alloy heat sink running around the whole chassis...its quite near the side covers.

    But I thought it odd that the heat was concentrated along the right side.

    I am a born worrier...maybe I should takle up stamp collecting?

    Hi John the QSO was SSB voice...all the heat is concentrated on just the right sise of the radio...I dont use digital modes.

    Nick, I just looked at your profile page, and saw you have your 450 sitting against the wall of your shack. You should actually move it forward a couple of inches. Having the cooling fan that close to the wall can impede airflow through the rig. Also, keep the vents on the top of the rig clear. Just a thought...

    Bit of an optical illusion...its a good 3 ins away....

    But thank you for your comment.

    I'd still move it out further. With only 3 inches of clearance, you could actually be blowing hot air back into the rig...

    Interesting key on the right side of the desk. Is that home-brew?

    Had the rigs top which is also half of the side cover off again today...I notice its secured direct with 2 screws to the alloy heat sink.

    Been having this discussion on a 450d facebook group...seems I'm not the only one having this worry over my 450d.

    One guy who went into is more deeply took a thermal image of the 450 after a bit of hard use...I will post it hopefully.

    All the same area mines get hot...or warm depending on your view.
