[knight patrol 60]

I have recently came across a 757 and it not transmitting on 11 mtrs ..is there a reset button for these radios ..or do I have to open it up /or is there a wee conversion I can do myself .

thanks

The stock 757 will not xmit on 11 meters, it a ham radio not a CB. Luckly if you do want to use it on 11 (illegal) there is a switch on the inside that needs to be set. Google it or someone else here can tell you.

thank you sir ...im selling the radio and the guy [bad rascal ]want it for 11 mtrs ...I will have a look at that ..much obliged ..

yeah, it's one of the easiest ones to "open" up, you don't even have to cut the "green" wire or snip a diode.

hey there mr squawker...to access that switch ..do I have to take bottom or top cover to access it ..?

thanks

 

[w9cll]

Here you go.

don't laugh ...I done the switch ..all good , then was txing on her ..and blew something ..no smoke or smell ..realised I was txing with high swr ..and power was maxed out [100 w] ...after all these yrs ..some people will never learn ...!!!??

is it possible it may just be a diode blown ? the rx is down a little too !!

it was on ssb ...am afraid you might be right sir ...someone else said it might just a have been the 11mtr filter that's gone ..because the rx went down v low to ..I can still receive signal and sound just lower signal ..!!

any ideas ??

dumbo the dude ..

That radio has no filter for just 11m. It uses bandpass filters. You may have blown something in the 10m filter section. Some radios do not like to be operated out of band. What kind of power output does it have on the different bands? Is the receive low on all bands? There is a small light bulb that acts as a fuse in the front end and if that blows the receive is low on all bands.100 watts is not a lot but it is a LOT more than a CB and things react differently under high SWR conditions.

Lesson #1-If you are not sure what you are doing ask before proceeding.

Lesson #2- Always check your SWR.


You may have just made a very expensive mistake if you took out the finals.

how is the RX on say,.... 20 meters?

can you load the transmitter into a dummy load on other bands?

 

[knight patrol 60]

I seriously doubt there's anyone here that hasn't poofed something and said, "hey, what's that burning smell" at least ONCE in their radio career. :laugh: I thought I knew quite a bit until I started coming here... and I continue to learn more stuff all the time. That's the fun part of it. Hope you get her fixed and back on the air soon.
