    good evening
    today what would be the best dds vfo transceiver to assemble today?
    I am giving a researched and it seems that all of them are capable of operating up to 30 mhz
    Is there any for operation in 6 meters or so and ask a lot of them?
    I'm a long time away from the radio I could put together a piece of equipment to encourage me to come back

    CRKits, the CS series, has a digital VFO made with no SMD components. See.
    See this location - http://www.crkits.com/ they have also for sale the HT1 CW transceiver.

    Best wishes in your hunting.

    Bitx40, uBitx from HFSignals.com, and coming soon the QSX from QRP-Labs.com

    All are SSB. AD9850 (or AD9851 DDS) or the Si5351A are used for the VFO. Pre-built boards are typically used for the chips.

    The CS series radio, that I gave you a link to, is SSB only. Basically, an upgraded KN-Q7A with a full coverage, digital VFO.

    I had build VFO use Si5351 Support Multiband Start from 1 - 30 MHz can generate output for VFO and BFO

    you can visit to my blog http://redywibisono.blogspot.com/ and email me for detail build from zero, attach some wiring diagram for main RF unit and linier RF Amplifier, PCB I got from YC3LVX, attach radio I Had build and right now can transmit multi band and digital mode.
