friend then with transistor which gives more power? with the 477 or 497? ‘
I have HR 2510 I love the radio, my problem the frequency shifting,
This radio make me contact for more than 125 countries confirm with QSL
former 43AT345 Op Ali

Et maitenant il genere des IM2 et IM3
The 479 is another obsolete part and if you look at the data sheet there is no improvement over the 1945.
what about a MRF479 instead of 2SC1945 ??
Hi Mark. Happy new year mate. Nice to see you back on here. Keep them coming mate. All the best George in Ireland…..73’s
i have 7 of these radios plus 2 2600 2 running the the 497 for 12 years 1 mobile the other base i get 40 to 45 watts on the usb on 10 meters all these years and never had a problem with both radios well i am not in the peak crap i herd the lincoln that has the mrf455 runs 75 watts that is the next radio i am trying to get
let me tell you that a friend of mine tried one against a 497 as saw no increase in power and as for 40watts from one of these radios is to much! that’s one of the reasons why i see so many for repair with fried output stages, the standard output should be 10watts AM/FM and 25watts SSB and i would think that was enough.
As for the 497 being available all i have seen are fakes!
mmmmmmmmmm another good ifo on my favorite radios but i wonder since the mrf 497 is available that gives out a little over 40 watts i do think that is a better buy i am not 100% sure the ones on the market are legit if they are i think it is better
Always like your videos mate. Keep them coming 🙂
