Transverter output level on 475 kHz?

John AE5X

I'm curious is anyone is using their 6XXX to operate on 630m and, if so, what is the power output at that freq?

I am currently able to transmit WSPR on that band with a beacon transmitter/amp and receive with the F6300 but I can't transceiver, especially at the speed of an FT8 QSO. I'd be interested in hearing the set-up of others who use their Flex on this new band.

The XVTR port allows continuous coverage low power (+10 dBm max).  10mW.

I'm using it receive only now. I am investigating amplifier possibilities. I am seeing a lot of stuff on WSPR using one of my "short" 80m verticals. For this band you can use a class D amp and get away with it. You're not doing SSB. You're doing CW and FSK. PSK may be doable but you need a more linear amp for that.

The transverter output level should be a max of +10dBm I believe. That is what you'll use on 630m and 2200m.

Edit: 10dBm according to Mike above.

I was afraid of that - a bit low for the transverter/amp I currently have which requires 100-500 mW (on 80m) to produce 22 watts on 630m. This equates to 1 watt ERP with my particular antenna but in 2 nights of WSPR on 630m I've been heard in 26 states including Hawaii plus ZF2.

Looking to operate JT9 or FT8 on the band but need a way to boost xvrtr output of Flex to 200 mW or so - I'll have a look around the web. I expect to see more construction articles in QST and elsewhere now that this band is finally available.

Ria, check out my website for what I'm using to transmit. I believe you could have an effective signal on that band for not much more than $100. Seeing that I was heard in KH6 on such a low freq was a thrill that will only be exceeded by working Bouvet in a few months ;-)

Harry has a few very suitable designs for wide band MW and LF amplifiers.

I love the amp made with a 7805. Reminds me of high school where I made a transmitter out of a 555 timer.
