Handy Andy I replaced the C173 and still no AM carrier. I will be doing some voltage checks and report back here of what I find. thanks so far on helping out

Handy Andy thanks for the reply *the radio from what I can see has never been touched all pots are sealed with red glue or something. *Yes the light is green and will turn red on transmit. *Radio has no mods I will check out the vari resistor and see if open. thanks

So I replaced the AM regulator and still no AM output power ssb is fine. Any further help appreciated

I did check and there is 13v in middle of the final and both sides nothing. When I key up the 13v in the middle goes away.

Further detective work points to the AM regulator so I ordered a 2sb754 regulator its a much better replacement and hope it does the trick. Will report back on my success or failure. LOL

I will give that a try in next couple of days thanks for the tip

So I checked for the 13v at the middle leg of the final and driver and both have 13 volts until you key the mic then nothing o volts. There is SSB power but no AM. I also set it up on my bench next to another radio and receiving the ssb audio but the AM is a cold nothing not even any audio. So...

Hi all I have a cobra 148 NW-ST and it has no Am out and the SSB power is about 8 watts. Radio has the 2sc 1969 and the 2sc2166 for finals. What would be the first thing to check I did try another 1969 and the same low ssb and no AM. There is audio modulation on the ssb and good receive audio...

I think I have some 4016 chips and will try to replace 1 at a time to see if it corrects the problem. Thanks for the information

I have had this from day 1 brand new, Seems the first led digit when I transmit is dim but when in clock mode its fine. Just when I transmit in freq mode the first digit goes dim. So i posted the schematic and would it be 1 of the 2n3904 transistors on the frequency end? Q4-10 and maybe the Q4...

Just tried some of the mirror sites many pages are gone on them also I do have the 14gb backup from 2020 and all seems to be there. Kinda sucks that Bennie will not give up the site to someone who is willing to keep the site up and running. CBC international is another site that is loosing...

Gone for good there are mirror backup sites but they have missing pages/information.

thanks for the upload much appreciated.

What did you delete off the 16gb file

Contact Moleculo and he will ftp an upload that seems to be the best way to get this done.

See if brandon7861 will give up the 16gb file for the ftp upload. I tried to grab a mirror site and nothing but missing pages.

I dont know seems no one offered to upload the file and just made a suggestion of some other ways to post the file. looks like brandon7861 has the full 16gb file to upload.

Well the best is to use your google drive and split the file to 4 files with winrar and upload the 4 files of 4 gb each to equal the 16gb file then peps can zip it back to 1 file. takes 5 minutes to make the 4 files it will ask you how much gb for each file.

Do you have google drive you could upload there if you have the 100gb plan. Or you can split the file in 4 files with winrar or zip and post to free sites like this that allows 5gb per file. https://transfer.pcloud.com/
