?Many years ago, as a teenager I had a full break in HW 16 ; ?had to give it up for my next rig.?
?I¡¯m starting to think there is a way to re-create it, using two UBitx, ?and the carcass of a HW 100 ??
?Use one of the UBitx as the receiver; ?
?Use the other as the exciter to drive the last two stages of the HW 100 ¡ª gives ?100 W output, ?although I¡¯ll add my relay daughter board, those two stages add additional useful filtering?
?Add in some diode networks, or maybe a pin diode if required, and some slick fast bias changes on the vacuum tube finals, ?which can be moved in and out of cut off, class C and class AB1....
One raduino ?can provide all the frequencies for both rigs; ?relays only have to change state when you Change bands; ? Transistor control of Vcc wires ; One of them is always receiving, the other is always ¡°transmitting ¡° ¡ª ?just instantaneously biased into operation and back out ?
?Lots of shieldiing each uBitx ?in some shielded compartment?
?Change a just few things and it does digital & regular single side band as well?
?Relatively inexpensive, high-performance full break in high power radio, ?Computer controllable, digital frequency control?
?Use some digital filter when using CW?
