Use direct digital synthesis as is done in high end broadcast amps.
No front panel operation. Completely controlled from computer via ethernet, wireless, usb, etc. Including fault monitoring, power on/off, tuning, etc.
Integrated receive filters, build in the model 419 filters for tx and rx, or a better rx only filter like the w3lpl design.
3.5 KVA power supply whether switching or conventional.
Auto tune amp that can be controlled from the front panel, computer, or exciter.
Solid state 1.8 - 50 MHz capable of 2.5KW CCS
Support for software defined radios, for example pulse step modulated IGBT based switching high voltage power supply (see http://www.j-hawkins.com/am.html), internal direct digital synthesis master oscillator (optional) and in-phase + quadrature modulation (I+Q) to support unlimited operating modes.
I would like a solid state legal limit amp, which is reasonably priced. What they are asking for some of these amps is atrocious, I paid less for my first car than for what they want for amplifiers now a days. Even tube amps, some of the prices are simply outrageous on tube amps. Make it on the KISS principle, somebody has to have a nice amp at even 1KW that doesn't cost a small fortune.
What about a legal-limit amplifier in a kit form? A kit that is assemble-only and requires no soldering. The only electrical work would be installing pre-tested circuit boards and connecting them with simple connectors, only requiring a VOM for testing as each assembly test is completed.
Automatic setting input level to achieve specified pep output. Preferably done without affecting the radio driving it.
Pass through antenna selection signals to detect antenna changes and trigger retuning. For instance, i have up to 48 (6 bands * 8 control lines) relay control lines from my antenna selection boxes. The amp would remember which combination of antennas and bands it had been tuned for and return to those settings or if it had never been used before force a new tuneup. this would have to be very generalized since i use ...more »
