[Elecraft] XV144 transverter firmware

Hi the Group, What is the latest firmware revision of the processor (PIC 16F872/1 SP) which is located on the front board of the XV144 transverter? The transverter I got has a PIC 16F872/1 SP with a sticker XV1.60E and the RF Board (main board) is Rev C , I guess it's a pretty old transverter.

Re: [Elecraft] K3 Autotuner malfunction

Don, At first (months ago), I looked at the antenna impedance at the rig and thought that it was a problem. It was an 80m horizontal loop fed with 450 Ohm line. It would be problematic to change the feed line length, so I did some calculations and found that 300 Ohm line would provide a better m

Re: [Elecraft] SignalLink USB

The "solution" is to run the SignaLink soundcard levels at a lower output level so you do not encounter distortion. With that being done, the SignaLink will likely not produce its PTT output reliably. With the K3, use VOX to initiate transmit rather than the SignaLink PTT - it will work just f

You need a pair of bandpass filters, such as Dunestar 600. You need a means of distributing all antennas among 2 radios, such as the WX0B Six-Pak. You need two band decoders, such as W9XT, for the BPFs/Six-Pak. You need an audio box (Dunestar makes one) that can select: left radio in both ears
