Re: Current v5 ubitx fixes adequate? Is there a thread about v4 fixes?


V3 and v4 need reduced leakage through LPF relays. Either add a pc board hosting added relays or switch the relays to axicom. Our club kitted a relay board designed by Gordon Gibby, but no one is yet selling it.

That leaves spurs associated with the mixer from 45 MHz to RF. Shielded inductors said to help, and additional 45 MHz filtering. This issue impacts 21 MHz and higher only.

No clear consensus nor kitting on these.
