QRPGuys AFP-FSK Digital Transceiver III

Many thanks to Pete (WB9FLW) who writes:

Morning Thomas,

Looks like our Prayers have been answer! 160 – 10, 5 Watts, single side band using a new transmitting technique , no more DSB!

All for 80 bucks (includes 3 band modules)

The v. III version debuts a novel firmware scheme for our Si5351A/MS5351M VFO which allows a move away from DSB transmission to SSB, by a new process we are calling AFP-FSK (Audio Frequency Processed-FSK).

Brilliant, Pete! This looks like a fun kit to build and certainly an affordable way to hit the digi modes! Thank you for sharing!

QRPGuys Tri-Band Vertical Antenna

On a tip from my buddy Eric (WD8RIF), I ordered a QRPGuys Tri-Band Vertical Antenna kit last week.

Not only will this antenna pair beautifully with my MTR-3B, KX1, and FT-817ND but I had completely forgotten I ordered it.

When I pulled the QRPGuys package from my post box, it was as if a little Christmas had arrived. I mean, is there a better feeling than getting a new kit in the mail–? I don’t think so.

Time to heat up the soldering iron!

QRPGuys new DSB Digital Transceiver kit

Many thanks to QRPer, Pete (WB9FLW), who writes:

QRPGuys has just introduced a new Multiband DSB Digital Transceiver for FT8.

At $40 it introduces a new price point for such Rigs as it includes band modules for 40/30/20 Meters! For those wanting to experiment with different Bands extra bare boards are available for sale.

The rig as it comes is crystal controlled for FT8 but fear not the main board includes connections for an external VFO. As an example one could use one of the very popular Si5351 VFO Kits and be able to QSY to operate the different modes available to the Amateur Community today.

Let the fun begin 🙂
