Hi Leighton, thanks for this, I'm meeting John tomorrow and 'round 2' will definitely look closely at these jumpers and the other suggestions. I've spoken to John and quizzed him as to whether he has

Hi Paul, I have just uploaded a file from Yeasu regarding mods to the frequency coverage of the 847. The alterations are done by removing or adding link resistors near to the backup battery. Leighton.

The following files have been uploaded to the Files area of the YaesuFT847@groups.io group. * /FT 847mod by Yeasu.pdf ( /g/YaesuFT847/files/FT 847mod by Yeasu.pdf ) *By:* gw3fsp

Look up mods for 847 I remember seeing something about out of band and Mars mods It's not diodes but chip resistors around back up battery

Hi Charles, can you tell me which are the ‘band split diodes’, I can’t see any reference to them in the service manual, which board are they on. Thanks again. Paul, G0ODP Sent: 16 March

Hi Charles, THANKS, I’ll check that as well and let you guys know. I appreciate your support. Paul, G0ODP Sent: 16 March 2021 19:49 To: YaesuFT847 <yaesuft847@groups.io> Subject: Re:

Check the band split diodes to see if some disabled 144 by accident. They are used to make bands legal in other countries

Nope. No error, that 0.5 to 6.5 feeds first The 'low' vco and over 140 The 'high' vco. Den tis 16 mars 2021 19:55paul warman via groups.io <paulswarman= sky.com@groups.io> skrev:

Nils, Dennis, thanks guys, either way this has given us a starting point for tomorrow...... we had given up for today, I needed to spend some time with the wife!!!!! However tomorrow is another day

Nils: Did you make a typo error ? I have been reading along. You said .5v to 6.5v? on the lower range and then you said the same voltage .5v to 6.5v on the upper frequency range. There was no

Hi, have you checked the voltage on TP2002 on the PLL board? Shall be between 0.5 an 6.5 from 108 to 139.995 and between 0.5 to 6.5 from 140.000 to 173.995. The switching of the two vco's is done by

Hi, I am trying to repair an FT847 for a friend, the rig works perfectly on all bands except 2mtrs. On 2mtrs nothing is heard or transmitted; it won't hear my sig genny at all. I have injected a

well till a couple weeks ago I needed one now I have to get rid of a 2100Hz Inrad or maybe i will just keep it in the radio disconnected till some day I want to sound tinny

Is there a market for the original stock muRata filters?? I recently thought I found a Collins YF-115S-02? ssb filter, sent the money, got the package today and found that someone had substituted

after I install my newly found stock filter (better for FT8 and other digital modes) I will have a 2100Hz Inrad to rehome it currently is in the TX side as that wont bother much for FT8/JS8call and

Hi Micky, I can answer one of your questions.? My understanding is the difference between the Inrad and Collins filters is that the Inrad being a crystal filter has a much steeper skirt at the

The FT847 doesn't have an actual built in SWR meter that I know of?if that's what you are looking for.? According to the copy of the manual that I have, the S meter will show reflected power ONLY

Hi All I have been looking in the manual but can find any refence to SWR display.? I have the FC-20 connected but get no indication of SWR reading? Thanks

For what it is worth. The 70Mhz enabled radios (C2) do not work well without modification. Approx 12 watts output for 15 amperes current draw, and a very deaf receiver. Add spectral purity on the

Hi Micky Ahh! I can see that there is a difference between the U.S. and the U.K model. Carey W4TFZ pointed out there is no 4mtr band allocation in the U.S. Thanks for the heads up Carey ? Hey
