    Good Oscilloscope to use,

    I use a tek 7603 with two 7a29 vertical amplifier plug ins with a 7b80 time base. Does everything I need it to too. The cool thing with the 7603 along with some others is that is has the plug ins. So, if one wants to delve off into testing something else, plug-ins can be had for those testing...

    First gen stryker 497 audio issues. Please help lol

    I love the early stryker radios. I have the aforementioned 2290 497 and a 1446 490. Both are awesome radios! Never will I come off them lol.

    Should I put the 102 back on?

    It depends on whether the radio is mounted above or on the dash. If above, 21' is not long enough. There is also a rubber grommet at the bottom of the kick panel on both sides under the floor mat.

    I saw co-phased antennas crossing 90 degree's!!

    Another reason to angle a coil antenna forward (when applicable) is to get the coil away from chrome visors (if the truck has them) or to get the coil out away from the body of the truck.

    Should I put the 102 back on?

    I have had the best luck getting a good swr/resistance/resonance with a 22-27 inch predator on those cascadias.

    First gen stryker 497 audio issues. Please help lol

    I found the issue to be in the band selector switch. Some contact cleaner brought it back.

    NO MORE TOSHIBA TRANSISTORS EVER ???

    I doubt toshiba halting the production of the 2290 and 2879 hurt their profit margin much lol. The transistors are just a small drop in the pond of all the products they have made/make.

    First gen stryker 497 audio issues. Please help lol

    Also would improper voltages measured at the points you described be a result of failed transistors tr36 and or tr38?

    First gen stryker 497 audio issues. Please help lol

    Would the failed components you described kill talk back audio?

    First gen stryker 497 audio issues. Please help lol

    This isn't a modification thread, more so a troubleshoot thread. I have a first generation 497 (the one that is loosely based on the ept3600 series chassis with the 2290). It shows perfect modulation on the scope with 110 watts pep according to the lp100a. The issue is that it has no receive...

    2sb817 upgrade? Dual final 959 needs a better regulator.

    Correction, I have a tip36c in it and am looking for something even more capable than it.

    2sb817 upgrade? Dual final 959 needs a better regulator.

    Is there a suitable replacement for the 2sb817 that Is capable of handling more current? I have a galaxy 959 with dual 13n10s with a 13n10 as a driver. It is doing 55 pep, I put a 2sb817 in it, but even it gets pretty warm. Is there a suitable replacement capable of more? Any help would be...

    Mag loop antenna tuning questions.

    Sorry for the bad drawing but this is what I am getting at.

    Mag loop antenna tuning questions.

    I was reading a little more on the faraday loop vs gamma match for coupling. According to what I have gathered, the radiation pattern of a gamma match is asymmetric because the gamma match is usually off center vs the faraday loop having a symmetrical radiation pattern due to the primary loop...

    Mag loop antenna tuning questions.

    Right on, I think I understand the just of it. Thank you both very much!!!

    Mag loop antenna tuning questions.

    So once I tune the gamma first for the desired 50 ohms, I then move on to the tuning cap adjusting it for resonance?

    Mag loop antenna tuning questions.

    From what I have gathered, I am going to have about 5.5kv at the cap, I intend on getting one that is rated a little higher so I have some leeway. My question is how to go about tuning. The gamma is match is for impedance and the cap for resonance?

    Mag loop antenna tuning questions.

    I have been doing some research on building a magnetic loop antenna. I built my first antenna (a half wave inverted v dipole), I am hooked and looking for another antenna project. My concerns are mainly coupling and tuning. As far as coupling is concerned I was thinking of using a gamma match...
