I don't like the bottons for change frecuency of mtr5b and mtr3 and that no input more than 12v exactly but the people who has it are glad.
This two reasons also why I don't like MTR!

I own a Tentec R4030 (youkits HB1A more o less) and I am very happy with it, in fact, I don't use my 817ND never in CW since I bought the tentec.
Now this rig is not being made? I found this which says the R4030 is not made by Ten-Tec, but it is? But on Ten-Tec website is not longer listed. Maybe they stopped to make it? How much this rig costs or only available now second hand? Was it a kit or ready built? Very good specs, my only problem with this rig is I would need 40/30/20 at minimum, not just 40/30. But otherwise it's great!

Tentec R4030 or R4020 are discontinued, I bought it second hand in ebay.

Actually there is a Youkits HB1B, improved (more bands, swr meter..).

Anyway, the better way to take idea about both is that you test it (LNR and Youkits) or almost watch videos about it.

All the people who know that has a Youkits/Tentec are glad, same all the people who has a LNR.

The MTR won't let you transmit out of band, so who cares what frequency you're one  :o

I also have an old Ten-Tech R4020 and really like it.  I hate to admit it, but I like having a knob to twist more than buttons to push ::).  I also like having all that info right on the display, but I'm a bit ADD so that's understandable...."Crap! I just checked my frequency 30 seconds ago and I already forgot it.  Now I have to push the button again and...Oh look!  A squirrel!"

Funny, I really like the buttons. The DFE, direct frequency entry with paddles is awesome too!

I hate to admit it but no doubt you're correct. The reason most electronics are so cheap is because of highly efficient automated assembly that is able to crank out finished boards by the thousands in very short order. I can see how interrupting that process to bag components for a  true kit could actually increase the price due to the labor involved. Such is the march of forward progress.

Indeed.

There is a trend I do not like regarding progress, in that more is better... More features, but more current draw, and no better sensitivity... The K1 has a great receiver and does not use a DDS, less noise... Now everyone wants to use a big PIC... A mini K1 would be awesome, nothing added, same schematic...

I wish I had a better idea what it costs to have SMT parts soldered to a surface mount board.  It's funny that I design boards for a living and yet I don't have a really good idea of what assembling the boards costs.  Our production runs are small (25 to 200) which is just the size you would do for ham kits, but I'm pretty disconnected from the purchasing process.

I bring this up because there's a chance that it's not much more expensive to have the SMT parts put on the board.  There's probably more labor in putting parts in individual kits than there is in assembling a simple SMT board.  For automated assembly, just silkscreen on the solder paste, load the reels of parts in the pick-n-place machine, let the machine place them, then run the board through the oven.  You only have to set-up once for a run of boards.  For a kit you have to cut the correct length of ribbon, bag & tag value of part for each individual kit.

How about making these cases (N)EMP proof? Any ideas there? It'd be nice to be able to make a lunch box NEMP proof.
