I would like to share some inside views and also like to have some critics to comment on our new upcoming project SB-7 Transceiver which is a single band 40 meter transceiver in S.S.B. mode (LSB only).

This upcoming Transceiver project is an improved version of our previous TRx project - JOTA TRx. The changes and enhancements for this TRx. would be: AUDIO FILTER, AGC CONTROL,S-METER & Mike Gain adjustments.The MAX Power of this Transceiver is 15 Watts.We will be updating this page and blog quite often so please take time and keep checking in for updates.
