    Schottkey diode/transistor opinions

    Yes, if I unhook coax from the back of the radio then the signal and noise drops to nothing on signal and almost completely quiet (even with volume wide open), but when I hook coax back up, the signal meter comes up to what the noise level is and the audio comes up a lot. Signals on locals...

    Schottkey diode/transistor opinions

    Wow, it can't be this simple, I feel like an idiot. After using it like above for several hours, I'm impressed. The signal reading on hash level shows about the same on any band/frequency or mode. One mode isn't higher than the other, no channel is higher than the other. The receive on all...

    Schottkey diode/transistor opinions

    Here is what I did just a couple hours ago while it's quiet on every band: I realigned the radio by just the signal generator. Went through entire process. Unhooked generator and moved all jumpers far away from the radios SO239 input (eliminate possibility of any stray signals from nearby...

    Schottkey diode/transistor opinions

    SuperLid, I can't locate any 1730's, and the MPSH10 is obsolete according to digikey but they do recommend the KSP10TA as a direct drop in replacement for the MPSH10. Will that ksp10ta work as they state?

    Schottkey diode/transistor opinions

    I may be chasing ghosts, lol... My mobile, after I aligned it, exhibited the high hash level also. When I hooked it up in the truck to my whip and get away from my house the level drops to what I feel is a normal level. Maybe that's why I haven't had anyone complain of low or too high receive...

    Schottkey diode/transistor opinions

    I did try the NTE583 diodes last night, not really any improvement on the hash noise level. If there was any improvement it was minut, but I did notice a slight improvement on weaker signals coming through (not by much though). I'm gonna try replacing TR17 this afternoon with one with a higher...

    Schottkey diode/transistor opinions

    Cable, If I unhook coax, I still get some hash noise (not as loud though) but the level drops to zero on the signal meter. I have read also that a leaky or weak transistor in the first stage could cause a lot of noise, this one must be very leaky then, lol... The meter on AM stays around 5 to 7...

    Schottkey diode/transistor opinions

    LC, My board is the EPT360014B. Mike, I may try the 85, thank you. Not really an issue, just the hash noise level is way too high after alignment, have to either turn the needle way down (which doesn't correspond to incoming signals afterwards) or detune the receive by 6 s-units. L6 drops it a...

    Flyboy, any specific brand/type germanium you recommend to cut back on noise floor hash level?

    Schottkey diode/transistor opinions

    I've been looking into these Schottkey diodes/transistors for receive/NB improvement. I've learned there's many different types of specific diodes and transistors you can use. I've heard differing opinions on the "improvement" diodes/transistors and wanted a little more info on the different...

    Another Saturn bias issue

    Got it... Output now: AM carrier - 1w up to 12w AM swing - 55w PEP SSB - 45w to 50w Reworked entire driver/final section, replaced all three bias adjustment VR's, triple checked solder work. Factory bias network still intact, except I used 4148 diodes for bias diodes. Radio reports on the...

    Another Saturn bias issue

    Thought of that myself and yanked all the disc caps out of the RF section to check. All check good and very close to their respective values. Gonna put all these back in, then look over very closely with bench mag glass to check for any cracked traces or bodged joints. I guess I will try it out...

    Another Saturn bias issue

    Is that BSide ESR02 Pro better than the standard TC1 or FNRSI component testers? I kinda like the look of that one.

    Another Saturn bias issue

    I'm gonna try the bias circuit changes on one of my personal Saturns after I'm done with this one. The guy wants it stock, therefore I can't tinker with the bias circuit on this one. I finally did run across a good Mitsubishi 2166 though, after going through a dozen or more I finally got one...

    Another Saturn bias issue

    Oh, I learn something every day, lol... I think all my 2166's are flat anyway. Highest HFe I can find is a 21 which is well below the minimum point for a 2166. I've got plenty of 2078' 2029, 2092, etc... but no more 2166. Gotta figure something out. Would a very low hfe cause a high current...
