I need SO2R with the option of in-band SO2R
Hi,
I have a Sun SDR2 Pro transceiver and it cannot work full duplex, so I cannot use alternating CQs during the contests, cross band. I also want to be able to work SO2R in-band, that is, CQing on, say, 20m and picking up mults on 20m, too. And I need the legal limit amplifier with BPFs.
I had previously had 2 x IC-7700 with lost of other boxes, antenna swiches and so on, which was a nightmare to set up and keep in order.
Can you suggest the right set up for me ?
Thanks.
Anton, ED8M

Now, how about the in-band option with a single Flex 6600 ? Is thos possible or do I need 2 x 6600 ?
Also, which 6600 you recommend - the 6600 or the M version ?
Gracias

If your going to use SO2R a lot you should have an amp with very fast band switching because the Flex is almost instant switching between bands. An SO2R amp.
If you like a stand alone radio all complete in one box then the M model is what you want. Otherwise an 6600 with a computer to run the SSDR software. What some do is get a 6600 and a Meastro that allows you to roam around remotely.
What I suggest is for tho op to read and do home work on the radios, then ask what he has trouble understanding, it would save us a lot of writing..lol
Yes the 6600 can listen on the same band in full duplex, BUT, you must be careful of the strength of the transmitter to the receiver by antenna placement, strength greater than +7 DBM can cause signal distortions and greater than 15 DBM can cause the auto protection to disconnect the SCU from the antenna to help prevent damage.. Besides, I don't think that most of the contesting SW like N1MM, will allow same band SO2R . Just be very careful of antenna placements , large antenna separation will help greatly ..

I think I have seen the in-band option in N1MM.
In any case I have used Win-Test and others for the in-band QSOs.

I'll be happy enough to perform Run on one band and S&P on another band.
You mentioned the 6400 on two bands - That is possible PROVIDING they use the same antenna; because it only has one SCU (Capture unit) so only ONE antenna can be used at a time. The 6600 and 6700 have two so each band may have its own antenna.
The 6400 example is: you may have a multi-band antenna with a single feed (e.g. 20/15/10 tri-bander) and have two receivers active (on the same capture unit / antenna connection) but on different or the same band (your two SO2R setups). NOTE: No Flex will permit you to transmit concurrently and the 6400 will be in "wide" mode, that is NO band pass filters engaged. The 6600 on two antennae has band pass filters on each antenna
As previously said - There is a lot in those boxes and it takes time for it all to sink in.
Also previously said - With two antennae active (6600 or 6700) they MUST be well separated if on the SAME band. I have done it but the risk is very high on a small antenna farm or field day.
TMI? - Drinking from a fire-hose OFF.

Simply put, yes, but you will have to share the same antenna. You will be muted on the other band while in CQ on your RUN frequency.
You set this up in N1MM as an SO2R radio. I am not sure how WinTest would be setup.
