I'm thinking of ordering this tranverter. I'd like it to cover full 144-148 2M band. Vendor says it will do full US 2 mtr band if the radio can do 28-32 mhz. Can 6500 do this or will I be limited to 28-30?

The specs say that the Transverter IF Frequency Coverage's are:

6300 =  100kHz to 54 MHz

6500 - 6700 = 100kHz to 72mHz

Yes.

I just purchased one of these transverters and want to set the Max Power (dbm).  I have set it to 0.1.  Any idea if that is the correct setting?  Also, I have to plug in the PTT into the transverter is that a match with the PTT output on the FLEX 6300?

I did figure this out last night.  Of course, the PTT from the transverter plugs into the TX on the back of the FLEX which is the same way I key up my amplifier.

I think I know the answer to this one but...I am not seeing my voice pattern on the panadapter when using the transverter.  I do see my mic levels and adjust them accordingly, however, on SDR as with normal non-transverter FLEX operations.  And, of course, I am registering a signal on the watt meter.

It is supposed to be that way Mark. Same happens when I TX on 144MHz out of my 6700.

Thanks! Enjoying my 6500 - even more with 1.4 !!
6500 just reinvented the SDR radio experience.

I use this same TX output for my linear amplifier and since I have had the radio it has always been enabled.  Curious, how would I disable it?

Ok. I saw the video.  Great one by the way.  I have the transverter store 2m rig.  The manual, for the transverter, says it can take 10 watts input.  What does that translate to Max Power (dbm) on the radio set-up config page?  10.0?

Mark, you might want to check the manual again - the sheet that came with my transverter said 100 milliwatts max drive. Unless you have the optional input attenuator board (which you don't need with the Flex) you should not exceed this input level. The output from the Flex transverter port was discussed here:

https://community.flexradio.com/flexradio/topics/milliwatting_with_the_6500_what_is_the_transverter_...

So you can't really damage the transverter since the transverter output on the Flex doesn't exceed approx. 31 mW.

FYI, 0 dBm means 1 milliwatt into 50 ohms. So +10 dBm is 10 mW, and +20 dBm would be 100 mW.

Doug, I did get it working after all with a Max power of 10.0 dbm.. The manufacturer says the transverter is ok up to 10 watts input. You think I should go higher than10.0 dvm on the Max Power setting? Thanks for your help.

I found out from the manufacturer, this morning, that I could push it to +40 dbm which would equal 10watts.

Hi  i got one of this and make caution it have tendency to turn itself into auto-oscillation just above the ham Band ,you will notice it by increase of current draw whit only PTT key ..

have try many thing for better in out isolation and stability but end result was 

finish i trash  and got a DEMI L144-28 instead ...

I got this transverter but it'a toy.... I made a comparison with Yaesu 991 and with strong signals is very similar but with signals lower than S3 very noisy. With very weak signals it is unuseable. Instructions written 50% in english and 50% in russian. uncredible.... To reduce the the output power you have to reduce trimmer Rinp but on pcb and instructions it's not labelled. I posted a mail to the producer asking help, no reply. Frequency stability quite poor. Make your own considerations..... I tried Gabor HA1YA and it's another planet, with full support from producer and an acceptable price. That's my experience

I also have an HA1YA 2m transverter and it is an excellent piece of kit! Highly recommended!

I'm happy with mine, got all three versions.   Now I'm, thinking I could actually put them all in one housing, and switch between them.

A kit? How much for 30W 2M version? Any chance it can work to 148 mhz, for US repeater use.

Hello,

I have a question about transverter usage. I am wondering if are there any bandwidth limitations for my 6300 receiver. Could I see the whole 2 meters band in the panadapter, (from 144.00 to 146.00 MHz) or am I limited to few bw KHz? For geographical reasons I am planning to buy the HA1YA transverter.

Hi Enzo,
The only limitations will be your panadapter bandwidth of the 6300 (7MHz) and / or the passband filtering of the transverter (i. e. The 2m band coverage of your transverter) In your case, you'll easily be able to see the full 2m band. I use a 6500 with a DB6NT transverter; although there are differences in our set-up (6500 will do a 14MHz panadaptor), for the purpose of your question they are the same in terms of being able to show the European 2m band. Hope this helps. See you on 6m Sporadic E soon?? Paul M0CVX

It is pretty neat to display all 4 MHz of the US 2 meter band. You can see both the input and output of a repeater at the same time. And you can monitor both, one in each ear, if you wish. On my 6500 I can monitor four stations at the same time if I want, and pan them to different places from left to right.

You are using the XVTR port with the 6300 which has no TX/RX limitations.
