Is anyone using their 6700 on 2 meters? How have you got it configured and was the effort worth it? I'm considering a 2 meter transverter but that would certainly make the 2 meter band option in the 6700 a worthless option, no?

Early on I decided that I wanted to use the 6700 directly on two meters - without a two meter transverter.
In July of 2013, a few of us got together, with Steve from Down East Microwave Inc., and defined the requirements of such an amp for the 6700. One that would take 1 mw and produce some serious drive level.... 25 to 75 watts of output.
Steve built such an amp for me - a high powered brick (75 watts out). Inside the brick is a preamp, sequencer, relays to allow one "antenna connection", and one RF connection for the 6700 XVTR connector..... there's a few other goodies in the box as well, see his specification sheet.
I happened to visited Steve two weeks ago and he says the amp is available with power output levels from 25 watts to 75 watts.
I have been using the 6700, this DEMI amp, and a grounded grid triode giving me 1,500 watts out since September of 2013.... without problem.
The setup is:
- using the 6700 XVTR jack
- connected to the brick,
- connected to a QRO amp, (grounded grid triode - 1,500 watts out)
- connected to the antenna.
I am COMPLETELY HAPPY with this setup. Been using it on meteor scatter for sometime now.
The other reason for two meters in the radio.... and probably the main reason - is to provide the ultimate I.F. for the UHF bands and above. Transverters for 1,296 Mhz and above.
Remember, the Flex6K panadapter can display over 12 Mhz of signals on the display. Most transverters use the 28 to 30 Mhz frequency as the I.F. ..... which is providing only 2 Mhz of band coverage.
This is one man's configuration that is working extremely well..... AND..... the cost of DEMI's brick is much less than the cost of a good transverter.
(I have no financial affiliation with DEMI, just a long time customer)
Just call DownEast.... they most likely haven't had the time to put it up on the web. I just visited with them two weeks ago.
Note: you can order it with separate two meter antenna connections.
I chose a relay internally so I could run the 75 watts standalone.... Or switch the QRO amp in for full output when needed.
They provide several models.... up to 75 watts output
Good luck, let me know when you're operational.
There are three threads relating to the 6700 and the transverter; Steve was open to suggestions.
I also am interested in a simple power amplifier for my 6700 on 2M but there is a need for more integration:
Transverter hardware and SmartSDR integration with:
2M In/Out - This power amp and no changes to SmartSDR is a start, but much more is needed.
A VHF/UHF transverter controller that interfaces with enhanced SmartSDR and the 6700 that either uses any (or multiple different) 12MHz slices as concurrent IF feeds assigned to different UHV bands. Coupled with SmartSDR changes that display real frequencies on the display.
I'm new to modern methodologies for VHF/UHF so have no experience behind suggestions; I do envision a stack of integrated inverter modules that concurrently communicate with SmartSDR and display multiple slices. SmartSDR can also direct via TX indicator which slice/transverter module is directed to transmit.
Can some experienced high band users help guide Steve's design choices for the upcoming 2M and above support. There is so much more than just 2M FM support here.

Okay, boy do I feel dumb. I called and talked to the folks regarding the amp and was told there is an option for an internal relay. Even after talking to them, I'm not quite sure what the relay is for and if I would want that option either now or for in the future. Its an additional $75 which is not an issue, I just don't want to order with or without it and regret it later. Can someone explain?
Terry, you mentioned that it can be ordered with separate two meter antenna connections. I don't understand exactly what this would be for. I'm assuming it comes with a single antenna connection and there is an option to have a 2nd antenna? How would you select it? Did you order yours with separate 2 meter antenna connections?
Norm - KL7RS
All of you folks who have already ordered one of these, what options did you ask for and why?
Norm - KL7RS
Now waiting 8 weeks to get it is going to be tough.

I would like to use it on FM as well. Any ideas when the 6700 will have FM along with PL tones for repeaters?
I don't use repeaters very often and have a dedicated rig for that. I mostly play on simplex, both SSB and FM. I'm really looking forward to the amp but now the October release of SmartSDR with FM seems like a long long time from now......

Question for the folks at Flexradio.
I purchased a Down East 2N75 LDPA and am extremely happy with the performance.
The problem is that Field Day is just around the corner and there are a few problems with the SmartSDR on the 6700.
When using 2 meters along with a 2nd panadapter, that is in any other band, the software is unstable. RF output power is not always remembered (dangerous for amps), and selecting antennas as you move from one panadapter to another is not remembered.
MY QUESTION TO FLEX is: Is there any possibility there will be a software release between now and FieldDay that will address any of these issues? I'm reluctant using the 6700 during field day this year due to some of these issues as there will be ops that are not real familiar with the rig wanting to get on the air with it. A special release just prior to field day would be wonderful news....
Works a treat.
