The K144XV module's RX architecture is almost identical to the external XV144 transverter. Same pre-amp and 2nd stage. Like the XV144, we will include instructions for removing the 2nd gain stage if you need to for optimized dynamic range (such as with antenna mounted pre-amps etc.)
We are now only using a 28 MHz IF with two different LO xtal frequencies to cover the complete 144-148 range, as per Wayne's earlier posting. 73, Eric WA6HHQ Giulio Pico - IW3HVB wrote: > It isn't exactly true that NF is unimportant on tropo.... otherwise no > one would be using a mast mounted preamplifier..... > The main issue then is preserving the dynamic range, as you pointed out.... > On the XV144 module is mandatory to remove the second rx stage to do > that in this case. > The point is, how many stages the new module have?
