[Elecraft] Transverters

[Kevin Murphy]

Hi,
I notice a trend with the Elecraft transverters, in that there is a 
second RF device, such as a ERA or MAV MMIC following the 1st RF RX device.

With most other designs I have seen, there is a filter between the 1st 
and second RF amplifier stages to limit out of band signals being 
amplified by the second RF stage.

In rural areas there is a lesser need for out of band  filtering, but in 
  suburbia there are many out of band signals.

Comments please?

PS I don't own  a Elecraft XV series transverter.
