[Elecraft] KPA3 in K3S mostly not working

[Don Wilhelm]

Carl,

Unless you are OK with operating at the 11 watt level and below, I would 
ask for an RSA and send in the K3S as soon as you get it.  Turn around 
times on repairs are typically 2 to 3 weeks depending on the backlog.

The K4 is not likely to ship until late April or early May, and I don't 
know how far down on the order list you may be - I surmise there are a 
LOT of pre-orders.

73,
