    cobra 25 gtl (taiwan) full restoration

    its not a fet. its an HG 2sc1969 in class C. i wouldn't run a fet like that. but yea i did a bunch of sh1ttesting and yea nothing gets past slightly warm, looks good on scope. for some reason things heated up more when i had the tip120 npc mod in there which is usually not the case. i got my...

    cobra 25 gtl (taiwan) full restoration

    so im back on it. threw another HG in, getting slightly less PEP. took the NPC mod out, for somereason things got hotter with that in reducting the carrier (weird) and it runs good with a 9w DK so i think im just gonna let it ride as a stout rig. maybe put it in front of 4xerf9530 mosfets which...

    LD 1x2 ERF9530 mosfet

    soo i found the problem. the relay had too much ohmic resistance in the signal path. swapped it out and im now getting much better numbers. if you do a 1x2 layout with these fets forced air is an absolute must. they LOVVVEEE current, especially in SSB. theres a reason why you don't see many...

    durability: IRF520 vs HG2sc1969

    in your experience which have you popped more of? honestly i dont have a good track record with the HG's. they seem to be more sensitive than mosfets

    Galaxy DX 959-300, project possible?

    Galaxy DX 959-300, project possible?

    what i would do is instead of rf sensing, i'd wire the relay trigger right to a point in the radio connected to the ptt or something so there would be no delay needed

    cobra 25 gtl (taiwan) full restoration

    took a pause and life got in the way....again. so last night i was fkin around with it. its too much drive for a single 9530 ekl FET and the PEP is enough to push the input swr up apparently annnnnnnnd i blew the HG final. idk why but it seems like HG 1969s are pretty delicate. i think somewhere...

    LD 1x2 ERF9530 mosfet

    i do not. i built a rocketbox250hd kit and started with that, and then made changes like biasing it a little harder. the single mos stage was a whole lotta trial and error

    LD 1x2 ERF9530 mosfet

    i tried to recreate the individual single and double circuits I previously built into a single package. getting closer to getting an ok tune on it, input SWR is perfect with the L match (6 turn air coil over a screwdriver and 270pf) so i'm thinkin it has to be the caps and the coil leading to...

    LD 1x2 ERF9530 mosfet

    so i have a few mosfet boxes that I homebuilt. i hooked the single up to the double and ended up getting 300Wpep ssb and 80RMS swingin over 250w on AM using a low drive PC 122 with abt 18w ssb and 3 swingin about 12 AM. theoretically 100W ssb and 60AM from that singlebanger driver is too much...

    Galaxy DX-959 Single mosfet version

    what i do with the 959 is the p5-p6 channel mod and I drill a cpl holes in the top case right above the counter. i get the small toggles and the body of it sneaks in between the PCB and bezel.
