This makes T4 a little broader and brings up the 27 MHz signal a little too. I also changed C36 from pf to pf. This increases the It helps the receive as well as the SSB transmit.

After the circuit mods are done, tune T1 and T4 for the highest channel and T2 and T5 for the lowest channel. Tune for highest USB output. You probably don't have to retune everything.

If the receive seems OK, leave it alone. The one thing I do disagree with in the Sams book is the tuning procedure for T3. I think it's better to go by the RF watt meter than the oscilloscope on TP3.

Well, I think that pretty much covers it. I now have channels from It goes higher but this is what I tuned for. The SSB mic sensitivity will vary a little across the band but not as bad as before. If you have any more questions, feel free to post them. My VCO was fine. I'd love to hook your radio up to a spectrum analyzer and see all the spurs you have created after de-Q-ing the filter.

You do understand the importance of a high-Q tuned tank following any RF final that isn't Class A, don't you? How much of the power you gained from the mod actually ended up on the intended freq?

Goos post. His goal was bandwidth. The mod just barely lets it pass a 1 MHz bandwidth. Hook it up to an SA and you'll see what I mean. And yes, SSB finals must be linear, but the linearity of the final or any driver is not the issue since the only requirement for RF linear operation is to conduct for at least degrees of the RF sine. The flywheel effect of the tank reproduces the remainder of the sine. And even though Class C amps also use the flywheel effect to complete a sine wave, they are not linear because they conduct for less than degrees.

Unless you are running Class A, the flywheel effect of a tank bandpass filter is absolutely necessary to avoid passing harmonics. X » Mon, 02 Aug Thank you. X Top 1. FS JC Penney Spam Report.
