Hello Rich, You may also wish to consider transverters from Down East Microwave. They are good at power and frequency stability. Do some search in this elecraft email listing, you will find some discussion in the past about XV144.

The internal one (K144XV) has one drawback: no adequate cooling! Cooling is done only passively using the left side of the enclosure. As JT65 on EME is a key-down mode you will see that power drops soon and dramatically, i.e. starting with 10 watts it will drop down to 5-6 watts after 2-3 overs already due to missing heat dissipation. So you will want to do some external cooling to lessen that effect (but you will not completely get rid of it from my experience). Besides this the K144XV is very sensitive, whenever I use mine I switch off the external pre-amp which is needed for all other transceivers overhere. :-) And don't forget to order the K144RFLK to keep the frequency stable. What you should also consider is which amplifier you want to use. So the XV144 might be the better solution if you need more drive power. If you want to think outside the box you can also check other manufacturers. For serious contesting and EME I'm using the HA1YA transverter ME2HT-PRO with +30 dBm mixer (http://www.ha1ya.hu/htmkepek/me2t_protransverterspec.htm) and 60 watts (including adequate cooling) to drive a GS35 amp. HTH - hope that helps! 73, Olli - DH8BQA Contest, DX & radio projects: http://www.dh8bqa.de Am 30.08.2014 14:26, schrieb Richard Thorne: > I'm starting to get the bug to try something different and EME has > grabbed my attention. > > I already have a couple K3's and would like to put one to use for > EME.
