Re: Spectra 146-174 110w capacitors

Today I got the last two remaining caps replaced, the two that are in the control head. Much to my dismay, the speaker still pops really loudly when pushing a button or when the radio begins to RX something. One cap showed signs of leakage. I guess I got some board damage somewhere. Maybe I could po...

Re: Spectra 146-174 110w capacitors

This spectra performs really well, I can now hit repeaters really far away, and it hears really far too.
Super stuff.

Re: Spectra 146-174 110w capacitors

Clean the entire board around the capacitor areas with 99% isopropanol (Isopropyl Alcohol). Dry thoroughly. Keep in mind the RF board is at least four layer, possibly six, so if capacitor goo got into the inner layers the only thing you can do for 100% reliability is replace the RF board. Just gett...

Re: Spectra 146-174 110w capacitors

I adjusted the pot and this has cured the problem 99%. The last 1% of the time it will still lose receive, for a split second, but this is still a great improvement, I just had a nice qso over 35mi, nice and clear audio both using 100 watts.
Not been able to meter the voltage yet.

Re: Spectra 146-174 110w capacitors

The caps have been replaced. Much to my dismay, the radio received normally for about 20 mins, though the audio was muted for a split second sometimes, and then the audio drifted out totally, as if the antenna had been disconnected. Now, the receive comes and goes, mostly it is completely gone. If I...

Thanks for your input, I'll do the replacement in any case. Just need the right parts first.

Re: Spectra 146-174 110w capacitors

Hi and thanks, I neglected to mention that I have done basic searches and of course read that article, but I still have doubts so here goes: Control head does not need caps replaced? "Note that the A9 (sometimes called the System 9000) control head uses different style capacitors and that contr...

Spectra 146-174 110w capacitors

Happy new year! I have become the proud owner of a T83FWA7HA9AK and it needs the capacitors replaced. (speaker popping, sometimes no RX) I have never bought a capacitor before, a techie friend will do the repair while I obtain the caps. However, I am a little confused as to exactly what I need to as...
