Galaxy 98vhp

Post by ricky252 »

Good afternoon to all, my Dad wants me to play with this Galaxy 98vhp it has the ranger board EPT690011D. Looking to open up the receive bandwidth and the direct Inject location. Thank you in advance and yes Hifi is addictive!

The mods should be the same as the 900 series radio's:

The direct injection point would be the R264/R265 end of C235

I had a resistor junction typo. I had 269/265 listed above but have edited it to the correct 264/265

right on yeah I see it, it gets injected right there beside r265. im doing the receive right now, I dont see c185. I see it on the sch. right there with c183 and c184 but its not on the board however there is a 103 mylar cap in the location of r266 where c185 should be so im gonna guess thats it and try that. Thank you again Goldfinger

If it has the TDA2003 audio chip, C185 is right in front of pin 2.

Thanks Goldfinger, I never did find C185 on this board, it does have that audio chip but I will check it later. Dad put it wide to the side cuz the Cobra 2000 blows it away on the receive, I tried to tell him it would lol. Im gonna inject the 2000 for him and Pops should be happy...

I injected c235 like any other galaxy , and I could drive it with my hifi setting but the guy tryed with his stuff witch almost identical to mine as far as stompbox app on I pad and I rig , the mics different, I have a c1 and he has a re20 , he says he cant get the radio to modulate , but when I bring it over here it modulates just fine what would be the difference our mics or did I do something wrong .

It may be the mic has lower output level. If he is local, take you mic over there and see if it has enough output then.
