Search for Q5 Signals. They work just fine.

This should help . http://www.q5signal.com/

If you order a common IF with 0-20dbm drive you'll be fine.  The XVTR port puts out up to 10dbm.  

These are a very quality product.

Hi Greg

Sorry.  I didn't know you where in the EU.  It was hard to tell from your post.

Hi Greg. I'm not sure how you came to that conclusion: from personal experience both the DB6NT and HA1YA transverter can operate with a Flex 6000 at +10dBm. In fact, my HA1YA transverter (MET2 Pro) can be configured for up to +37dBm !
Check out the HA1YA website.

The only problem is it only advertises 75w out put which means it really only puts out 50 or 60.  I want at least 1k.

Roger, are you guessing or have you tried one?

I use them and they deliver what they advertise.  

If you find a 1KW transverter, I think many would like to see it.  Normal transverter operation is to used a 25W drive unit and then add on a power amplifier on the back end.  Have a look at what the EME guys do for 2M when they use an HF IF.

I did some research on the 9700 and I did find some things you may want to research.

It does have some drift issues and while it is good to 0.5ppm, that means your drift can be substantial.  At 400 Mhz, it can drift around by about 200hz and be within Spec.  There is a video on YouTube that shows this.

I am not sure how you did your sensitivity research on the Flex with a Q5 transverter.   I will do some actual research on this, but our CTO is a weak signal person and he would not put up with poor sensitivity.  

The one advantage of a Flex as the IF is that I can be on multiple Transverted frequencies at the same time on the same antenna and the same amplifier.  Something you are not able to do on 9700.  In fact, the other day, I was monitoring 144.200 on a quiet band, and I would have totally missed the qso on 144.210 and I was also doing and decoding FT8 on 2M at the same time.  That was a deal breaker for me.

OK, I misread your request. how about 432:

Mike,

I am taking the leep of faith and going to try the Q5 product on the Flex 6400M. Can you tell me what options you would feel best to select  when ordering one for 2 meter.

For a 6400, I would just tell them common IF and that your output power from the XVTR port is 10dbm.   

For power out, that is your preference.  Just make sure you have a powerful enough power supply to power the XVTR.   You will need an RCA keying cable and a BNC to BNC patch cable.  Output from the XVTR is N connectors.

Common IF
Common RF
0dbm - +20dbm drive
PTT - low ground
I would get the High Stability OSC
Standard 28Mhz IF

You can also call them and talk to them.

I just told them I had a 6600M and they knew what to do.  A quality product. 

Gary W9GD

Mike and Neil thank you both . Will order in AM can’t wait to try it .

Mike I received the Q5 150 watt version.  I hooked it up and was a snap. I had the DBi set at 12 it worked fine. However 2 days later i tried to get more power out so i raised it to the max 15 dbi and now i cant get any output on FM appears to look like just a carrier.  Did the Q5 take a dump or what am i doing wrong. Possible a setting in my 6400M ? My Flex had to reboot when Smart SDR crashed . Then i ran the Q5 from the radio directly same issue. I tried HF and all modes work fine.  Anyone have any suggestions I can try ?
