The RF output increase modification, I didn't see the results posted.
Actually it didn't really make any difference. I did the super swing mod and it works. I did both on one radio, 949 and no difference than just the super swing mod.
I've done all the mods listed and get good reports. Unlock the clarifier as instructed on CBtricks site and it's a great little ssb radio for the money.
The 919,929,949,959,979 all can use those mods or a variation of them. The only thing is very little rms output. From 2w carrier even with those mods you get little forward rms. The ones I have done usually get 8-10w rms without doing the "rf increase mod" or removing the limiters.
i have no rms figures (save the carrier) but here are the figures reflecting consistent results after setting up several dozen of the 949s and 959s....
AM High Power: 6 Watts Carrier>25-30 Watts PEP
AM Low Power: 1.75 Watts Carrier>20 Watts PEP
SSB Power: 30+ Watts PEP
these figures were obtained without any modifications....
