OK, James. I was under the impression that the TS2000 ran about $2500 without 1.2 GHz. So you are right I have $2800 in my K3/10 with KRX3, KXV3. Add $79 for the ARR 50-MHz preamp and $479/ea. for the assembled DEMI 144/28 and DEMI 432/28 xvtrs. If one can buy a new TD2000x with 2m/70cm/23cm for $1850 then it is clearly cheaper. Without 432 I will have nearly $3800 in my radio+xvtrs. But the K3 has way better weak signal specs due to the low phase noise LO's and a huge lack of birdies due to its simple dual down conversion architecture. Although it will not do satellite at this time I suspect sw changes coming for that, given enough VHF operators buying one. The K3 is rapidly becoming the microwave operators radio of choice. To be fair, I did not purchase it with satellite in mind. My prime objective was for a super IF for VHF-microwave and eme. I am building a 300w HF PA kit for only $150. I am hoping that it will operate near 100w on 6m, but that remains to be seen. 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-600w, 432-100w, 1296-60w, 3400-fall 2010 DUBUS Magazine USA Rep [email protected] ====================================== _______________________________________________ Sent via [email protected].
