OPTIMA MK3

OPTIMA MK3

Optima MK3 2012 ver 1.8 operators manual

Usage comments: Have had this radio on the bench now for 3 days.  Very stable. RX seems  same as previous models but seems to handle the FM  interference better. Maybe we have not had the bad stuff from Russia yet! The VFO /channel selector is pretty stiff compared to my MK2 which spun pretty easy. In fact I started using the up downs on the mic to save my delicate fingers!! Icom mic sounds more natuaral to some but most give a big thumbs up to the original mic.  Lots of depth.  Other than that it just keeps ticking along as it should.

We have been examining the MK3 Optima for a week now and were not happy with theway the mic sounded on SSB so requested a change and now it is sounding the way we like so it is ready to go. While originally the MK3 was supposed to be a new board with all the recent improvements to the circuit built in alas it is not the case! The board is still the same as the last two productions but there has been an update in the software to improve stabilty on SSB.

Quote “PLL SYSTEM:       MAJOR NEW CHANGES, IN-ORDER TO OPTIMIZE A STABILITY PERFORMANCE OF SYNTHESIZER IC MB1502 WORKING FROM A LOWERST FREQ. RANGE, CAUSED SSB NOT IN PROPER WORKING OCCASSIONALLY, IT NEEDS TO CHANGE OSC FREQ TO 4 MHZ, AS TO KEEP A SIGNIFICANT DRIVING LEVEL, THUS, XTAL AND BUFFER MODULE HAS BEEN CHANGED IN THIS MK-3 VERSION.”     there you have it.. from the horses mouth!

The mic circuit has been modded a little and the SSB sound is fine. Medium without too much low emphasis. Not too happy with the way the fan is attached. previously the fan was slightly recessed. Now it is tacked on the back..tackily at that. I much preferred the fan with the slight recess into the heatsinks as it looked ao much more professional. This is the quickest way to determine if you have a Mk3 or not. The other way is to look at the wording on the front panel.

If it says 10-12m AM/FM/SSB TRANSCEIVER you have the new MK3. Actually there is no functional difference between this and the previous model. Looks like the dual functioning knobs are a bit heavier duty and the yeticom Optima has a slightly different mic layout. Not sure if all the radios will be set up like ours but this was the one change we requested after testing the radio.

I will have more after I get my Mk3 out of customs and on to the bench where it will replace the version 2 with the func on the VFO I have been using for some time. I will be performing side by side tests to see if I can tell any changes in the way the radio performs. I think this could have been Optima ver 2.6 instead of Ver 3!

    Hi, Just bought mk3 Optima in the UK. Haven’t really tested yet but would have preferred 6/7 digit readout for ssb? Box shows 7 digits and they do appear to be there? Just not used.. Not keen on rubber knobs as I think they may wear quickly with use. Not sure about the stiff clicky vfo either.. Display resorted to dashes after being on standby for a while but returned after keying mike. Although I don’t use a roger beep I couldn’t activate one by switching on while holding ptt down, maybe excluded on mk3? Rf gain works in reverse? turning clockwise to increase sensitivety rather than reduce it Having said that its a nice compact and solid radio at a reasonable price. Tony

    which pot do i turn to get my mk2 on frequency (SSB) ?

    • dd182003 says:

      depends on how it is off frequency…USB or LSB…you don’t wish to adjust the clarifier or is it sitting just off the indent?
      Hate the indent! Will email you re this..

  6. rob hicks says:

    I have a new mk3, tx and rx are inline with eachother but the clarifier has to be at 90clock to be at zero beat with received stations, is there a trimmer to set it at the 12.o clock position >

  7. Rob says:

    Radio was replaced with no quibble, a true gentleman who was keen to help.

    These are great radios. I use to have one when Radio Shack sold them at their 10 meter radios and it only did 10 meters! But now with 12 & 10 meters and a few extra functions should be a better radio!! Not positive if the Ham MK3 can be converted to CB or not.. I sell the Ham MK3 on my site…

    • dd182003 says:

      You sell them and you dont know what the frequency range is. Open one up and have a look!!

      • Radio Dr says:

        I know what frequencies most of the MK3 radios are capable of… But I don’t know if the ones I re-sell will adapt to 11 meters or not. I do not stock them.. I use drop shippers.. I get questions about it, But I’m assuming its only 10 & 12 meters… I have not ordered one yet for myself.. Will do soon..

      • dd182003 says:

        So where do you buy them from in that case?

      • dd182003 says:

        And FYI the optima covers 24.5 to 29.995 out of the box. It can be set up for 10 and 12m only or 40ch CB only with internal jumpers.
        I am sure the specs and manual can be downloaded from the yeticomnz web site.

    I’ve had a mk3 for about a year now and it’s been excellent, however I took it out of my car over winter where it sat untouched, I’ve just fitted it in my van but it’s not working properly. On SSB I can hear myself through the rig and I only seems to peak at about 20w, on FM it peaks about 40w. Any help would be really appreciated. Thx
