|The front panel is fairly logically laid out, with indicators for all important functions.
|This is the basic circuit. You are invited to modify it as required or necessary. Note that when the preamps are
off, the gain controls are removed from the circuit, but the sensitivity controls remain active. Also note, the
attenuator allows the adjustment of the overall output level without disturbing the relative antenna levels. The
co-phase and pri/sec switches are what permits selection of which antenna will be phase controlled, and in
There are some dissimilarities between the schematic and the older panel layout. Of course, all the final details in
flexibility are at the whim of the builder.
Have fun with this one, and report your results for the ongoing development.
|I have modified the original phaser schematic after the recent design updates I've researched and
subsequently tested. The new circuit is shown above.
This is an on-going development project, so please bear with me if you have already begun assembly. I
assure you that this version is much improved in terms of functionality, effectivity, and ease of use.
Caveat: (A preemptive plagiarism statement).
I have many, many hours invested in the development, testing, and evaluation of this project. Some of my R&D, and subsequent
testing has been based on the technology employed by the Timewave, Quantum, DX Engineering, and MFJ phasers. For good or
bad, all have been evaluated to determine their technical suitability, effectivity, range of utility, and ergonomics. Still, some
further development has been based on the excellent developmental work of Prof. Dr. Dallas Lankford. I make no apologies for
studying the work of those who have come before me, since any good engineer should study the teachings of his/her mentor(s).
Please bear with me during this process, and thank you for your support and e-mails.
