Re: [Elecraft] Copy cat - no way
Howdy Walter, Really have to agree here. To most, if not all, of these guys, QRP mean slow output power. OK, great, as far as it goes, but you’re right. Whereas Yaekenlincowood just create what amounts to a low output power version of something else they already have more or less, Elecraft takes the whole design into consideration. If you don’t believe, and who here doesn’t, just look at, as one metric, current draw on receive. OK…is that really power efficient? Even the Chinese designs like the Xiegu X108/X5105/G90/G1M have pretty high current draw, relatively speaking, and they were never designed with QRO counterparts. Elecraft works hard to optimize the whole design, taking into account use cases for QRP, many of which will involve outdoor use with extended power requirements away from commercial electricity. Iteally matters. OK, every design has compromises, but I think Elecraft is very mindful of which compromises are acceptable to the end goal.

Elecraft has the best I have found for portable and QRP comms. Lots of low power competition just dazzle the rig or spiffy the cabinet but Elecraft is the real winner to me. 73, Walter Dufrain - K5EST QRPcw--> KX1,KX2,KX3 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

And...there is little doubt that it lacks the advanced exotic capability to do really really hard things like operate its iambic keyer in mode A. I've never found an Icom rep even at Dayton who could explain why that was impossible technology for Icom, other than blame it vaguely and stupidly on "the engineers". That's if I was lucky enough to find an Icom rep at Hamvention who even knew what I meant when I asked about "iambic mode A". The other IC-705 characteristic that is adverse to outdoor operation is its very dark color scheme. That makes it an effective heat sink for solar radiation...never a good thing unless operating in polar regions. :-) Unfortunately Icom is **not alone** with the gratuitous inclusion of such a harmful "feature" in a small radio.

Re: [Elecraft] Copy cat - no way
I noticed that the IC-705 drawing shows an ATU connector presumably for linking to an external ATU. Maybe the intended market is not SOTA, portable, Field Day, or anything outdoors. Perhaps a paddle is in the accessories we have not seen yet.

Another question is whether the IC-705 will support full duplex operation (e.g. UHF/VHF) that satellite operators need for working linear and FM satellites. I’m not aware of any current field radio that does UHF/VHF full duplex. Most satellite operators typically end up using two radios for linear satellite contacts which adds complexity and bulk. A second question is how it might work as a mobile rig. It isn’t clear from the photos I’ve seen whether there is a mounting arrangement that would work well in a vehicle. The fact that the new model is a ‘705’ suggests a connection to the IC-706, which works well as a mobile rig with an easy-to-mount control head and a base that provides 100 watts. One has to wonder if Icom will eventually provide for the IC-705 a 100 watt HF option or a UHF/VHF option as an external amplifier for mobile use. FWIW.
