[VHFcontesting] Icom & 222 Activity

[k3sk at buckwalter.co]

Marshall,

It sounds simple, but its not economically sound.   If the mfgr adds 222 MHz it cannot be marketed in much of the world.  Many countries have laws similar to the FCC "type acceptance" and if the 222 band is included it will not be allowed to be imported into many of those countries at all.  This would mean the mfgrs would need design and build several different versions.    A single band rig or several versions of a multi-band VHF/UHF rig are about the only options and for a Region 2 only market, the single band is about the most cost effective choice.

Why anyone would want a single band all-mode 222 rig is beyond me.....just another big box that I need to find a power supply for and space on the operating desk for.  What we need is a rig that has 6M, 2M, 222, and 432 in it(for sales purposes, you would probably have to have HF too).  We have the IC706MK2G series of radios(the 706, 7000, and its successors, and the Icom 9100 series rigs).  If the rig makers can make a rig that works on 2M and 432, they can make a rig with 222MHz on it. Maybe it would only make 25W, but that would be FB as it is enough to drive a big TE Systems amp or a solid state 222 palette amp.

Adding 222 to a rig that already has 6M, 2M, and 432, just cannot be a serious engineering challenge.  However, we just don't seem to be able to get I, K, or Y to do that.

The initial response I got was that I was the 3rd or 4th person that had asked that that day!    Then after educating them a little on the current SSB/CW/FT8 activity and telling them about the recent selling prices on used IC-375A, they seemed interested and said this was something that would be brought up at post Hamvention discussions with ICOM HQ.      This is a good start, but unless everyone starts contacting them to put a little pressure in their marketing, I wouldn't hold my breath.

I think he has ordered two boards for us. You do have to supply the LO but most people use those synthesizer boards available from DEMI and Q5 Signal. We will report back as things progress.  Now I know that many people have no time, and others go cross-eyed trying to work with surface mount parts, but I have had good luck with SM parts so far.  Magnifier glasses and laying off hard drugs helps.

Possibly a 222 MHz band could be added now with technology where it is, with much less effort.  I would always go the transverter route with a high end HF rig rather than a VHF multi mode rig just because you get more bang for the buck, but many people have the opposite opinion.
