    RM Italy KL 503 Crunchy

    Presumably the HD version has no driver? I’ve got an hd sat here and it has the driver still and a 7db pad the later ones had a different board design and that cutout by the relay is where the pad goes. Note. The 703 uses 2x 3db pads for input attenuation

    Presumably the HD version has no driver? Still has the driver they fit a 7db pad into the relay.

    RM Italy KL 503 Crunchy

    If this bypass is done the SWR will be high. Mine was flat now it’s a 3 so I have to use a z100 auto tuner. 100% there is a lot of input swr with this mod unfortunately, I’ve tried tweaking the coils with no success so far.

    maxlog M-8800

    Ok press 10k or nb while turning on Release and press function for 3 seconds Bfo tuning appears and main vfo adjusts value. Auto saves when switched off The rest is up to you but make sure you have a 10mhz gps and a nine digit counter Or rubidium standard.

    Also has anyone found the service menu? The frequency has shifted in this one a bit

    maxlog M-8800

    ive still got one of these awfull radios, after i program custom frequencies i send to raido and it then resets itself to band 2 which is usless as you then have to re enable band1 which wipes any custom channels that might have been there. great potential let down by hopeless programming.

    Wire in an external PTT line to a CB radio

    I may know a guy over here who can re write the file, possibly best in smt as well these days. I’ve no problem sending the revised gerber back over to you if he can do it.

    Wire in an external PTT line to a CB radio

    Any chance of a gerber file? I’m in the uk and the postage is horrendous on the eBay. I’ve got a lot of guys over here who would benefit from this cool idea

    Problems with NEW RCI 2970n2..

    I Set 520’s at around 3.6v gate. I test first in dca pro to get the switch on but 3.6v is usually ok. Thanks for the info I’ll check cb tricks as well and make up some feedback boards.

    Problems with NEW RCI 2970n2..

    Anyone know the value of those smd caps on the feedback boards? I’m going to make my own boards. The resistor is probably 68ohm 2w at a guess

    Stryker 955hpc over volt

    We’ve got it lit up! permanent dc low warning even with dc warning disabled bias ok good finals fitted no tx power but going into tx Rx seems ok.

    Stryker 955hpc over volt

    Had a 955 hit the bench and he’s 24v it in a truck I’ve changed the obvious parts E510 (exploded) U506 blown L511 made no difference D513 made no difference Finals short (disconnected) Tp 504 505 506 507 508 all 2.2v J505 2.2v 8v by J501 2.2v Q529 Q530 both 2.2v Anywhere in fact that...

    Ranger 2950dx cpu board options

    Off to the spares bin. at least I can use the cpu in something else.

    Ranger 2950dx cpu board options

    It has the L10-11-12 cans from a known working radio in it and still deaf on ssb. Q23 is the problem I’m sure if I touch this leg with anything conductive the rx Comes up quite a bit. But again this is a known working part so I guess the voltage is dragged out somewhere along the line

    Ranger 2950dx cpu board options

    thanks Chris they seem ok. If I touch the q23 area the rx goes up but not to full sensitivity then if I reduce the generator then increase it doesn’t recover the signal again. changed q23/25 and the diode i mentioned before. am fm is spot on very sensitive Rgs

    Ranger 2950dx cpu board options

    I’ve got it working Chris was a bunch of dry joints. only fault I have now is ssb rx is quite low I’m guessing check q23/25? Maybe the diode next to L12 rgs

    Many Thanks Chris I will go through the suggestions rgs
