Has anyone tried any of these yet?

http://www.ebay.com/itm/131456218664?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT


I ordered one about a week ago.  Looking forward to checking it out.

I plan to build it "inside" the case of an old HTX10 I have modified for transverter use.

If you have tried one, I would like to hear your opinions!

I have the 222 unit but have not finished the project yet.
The receive works but need to sort out the xmit side.
The documentation is half in Russian and sparse. These are made in the Ukraine.
The drawings are a bit different than we uses here so you need to study them at length to associate what's going on.
You will get an attenuator board, a main board a small cabinet and a bag of supporting hardware.
You need RG 174 coax to properly connect the two boards.
The boards are all SM components and done really good.
E-mail help is available.
Good luck.

I have one, I think for the price they are a pretty good deal. I bought just the transverter board itself. I mounted mine in a diecast aluminum box just larger than the circuit board. I am driving it from the 1 mW transverter output on a K3 (no attenuator needed). According to the documentation that came with the transverter that should not be enough drive, but I still get about 8 watts out.  One thing that would be nice is if there was an easy way to set it up for split-IF connections.

Be sure to check the frequency on it before trying to make contacts. The first time I used it was as portable in the June VHF contest this year. It turns out mine is about 13 KHz off. That led to some confusion until I figured it out!

Thanks for the reply fellas!

I will be sure to check the frequency.

My frequency was off also. 10 kc or so. I did not like the connectors. And it would be nice if they would have split the if. Mike

Got an envelope in the mail from the Ukraine yesterday Smiley

At first I was a bit worried.  It was just in a paper, letter sized, envelope.  I was afraid there might be damage coming all the way from the Ukraine in just an envelope...  But, inside the board was wrapped in bubble wrap and plastic and was in good shape.

I hope to get time within the next day or two to get it wired in.  I dug up a few feet of RG174 from the junk box.  I have an HTX10 already modified for low power transmit.  I'm planning to mount the transverter board  inside the case of the HTX10.  Looking inside the case, there should be plenty of room on the bottom side of the radio, just forward of the internal speaker.  Any opinions on if the HTX case will be enough heat sink for the power transistor of the transverter?  Assuming light duty SSB/CW operations only...

I plan to document the "construction project."  If anyone is interested, I will send you a copy when I'm done.  Just hit me up at k9zf at yahoo dot com.

With any luck I will be on 222 in time for the ARRL January VHF contest.
(When did it stop being the January VHF Sweepstakes?)

Any news on the transverter? Enquiring Minds Want to Know™!  Grin

I'm thinking a couple of those would be great for "throwing in the backpack" for Field Day, or for travel with the nifty little QRP SDR HF rig I just ordered.

I have one of the 2 meter ones with attenuator and case.

You can have the whole package for $50
