Anyone have any experience using this transverter with a FLEX?

http://transverters-store.com/144mhz.htm

It is $100 shipped, but you need to put it in a box with your own connectors and heat sink, etc.
It is Russian  or Ukrainian made, I think.

If they stink, does anyone have any better suggestions that won't break the bank?

Yes, I purchased one of them, great quality and it works great!  I would not hesitate. The one I purchased was for 220mhz but its basically the same board.  If I did not already have a 144mhz transverter, I would have purchased another one.

Ken, first thing to consider is if the transverter has a single or dual port IF (I'm sure it's going to be 28MHz)
If it has two ports, one for tx and the other for rx, you may want to consider looking inside and seeing if it is easily modified to single port.
Another question, do you have other transverters?
Single port is easiest to interface to the single port on the Flex.
If it is dual port, and you don't want to modify the unit, then you will use a small relay to switch the single Flex XVTR port to the two ports on the transverter.
Next thing to consider is the power level needed to drive the transverter; hopefully is will take low level input, this is most desirable.
Last you will need to account for the PTT line.   If you are running only a single transverter then it will be simple.  For more that one transverter you may want to look into using the bias tee method to key PTT and let a single relay switch bands.
Some food for thought.
Congrats and welcome to the VHF world; some day when there is enhancement, we should be able to work.

All mind boggling to those not used to the transverter scene. Long learning curve needed

Not a USA offering but vk3xdk sells one.
I started with a NE612 with 10MHz LO and 10 meg IF but now use Flex 1500 with filters and amp or a 6500 for 630M.

I did see that one, but the import duties + vat  make it a bit steep for my pocket. I can easily build one my the arthiritis is making it hard to build stuff nowdays.

Building filters and an amp for the Flex radios is the way to go. Then its all digital without the noise and distortion in older radios.

PRE-BUILT NOW.

Sorry I had troubles posting above and I am late to this.

I see the pre-built are on http://transverters-store.com/assembled_tr.htm

I apologize I was not up to speed on this. Want a converter but waiting on Demi.

Sorry for any confusion I may have caused.

Hello Flex users,

I bought one, tested on the bench with my sig gen and spectrum analyzer.  Works as advertised!
I love the xvtr integration with the 6300.  Don't push more than 2 Watts if you want linear operation.  Anything over will go into compression.  I use with a Mi Rage B310G.  Again anything over about 50 Watts is fine for FM, but not for linear operation.

Best, John KB1YFD

Would this combination work with the Flex6300.
Mainly to be used for local repeater FM, and aurora work 2m ssb.

I just bought the assembled 2m transverter last month and am still testing it.  I picked up a VHF/UHF watmeter at the Dayton/Xenia Hamvention so I can test power drive, etc.  

My first surprise was how sensitive the xvtr is to drive.  I have had to turn my XVTR port output WAY down to keep from running it at full blast (15 Watts).  I am trying to stay below 1.5 - 2 Watts for spectral purity, and it doesn't take much drive for that.  I have only made one SSB contact so far, but a lot of repeater work out to 40 miles with my beam at 45 ft.

I hope to do some July Tropo on 2 Meters this summer.

Ken, this has always interested me, I have thought of doing this for a while. Nice to hear what your learning and glad it is working well for you. Is there lots to set up to get this working?

I have one of the ukraine 144/432 transverters available if anyone is interested $60 shipped US.

I bought both DEMI 50 watt transverters and no longer need this. 

I also have a transverter store 432 that works good $50 shipped US.

And I have a 144 transverter store that works but developed an issue when it has been on for a while it will intermittenly go into transmit on its own. make an offer

At FDIM this year J. Duffey, KK6MC gave an excellent presentation on adding UHF and VHF capability to your QRP station.  Out of that talk I saved a link that might be of interest to all who have the Converter-Store devices.

I think that the 30ppm Lo stability is really lacking and I agree with KK6MC's evaluation of these transverter.
