Small PCB with 3x7segments LA6780 and MAX7219 driver. I2C and power connections available.

Breakout board for AtMega 32u4. Fits snugly in a breadboard.

The Yaesu FT-736R remains a popular satellite ground station transceiver. However some modern computer software is not compatible with the CAT interface on the FT-736R. Ham Radio Deluxe, in particular, does not support the FT-736R. Ham Radio Deluxe does support the Yaesu FT-847 which has similar features. We can solve this incompatibility by programming a CAT interface to present a FT-847 to the PC and emulate the new commands not supported on the FT-736R.

Features not present on the FT-736R are ignored. Memory channels are not supported and the radio must be set to VFO, also satellite mode must be set to VFO, before enabling CAT control of the radio. 1200 MHz is mapped to 200 MHz because the FT-847 does not have 4 MHz digits.

== Notes

• HamSpot.com sells fully and partially assembled boards

• N6BIL FT-736R Hardware Emulator

• This is a slight modification of the GPL v3 licensed interface designed by Chuck Jones, N6BIL.

• The concept for this interface was developed by Dave Dowler, KA6BFB in 2010. He developed a proof of concept in software using VB and Windows.

CUI PJ1-023 DigiKey PN# CP1-023-ND

Bluetooth enabled arduino uno clone. Designed to work with HC-06 module. Custom firmware basic interpreter hence “basicduino”.

This board DOES NOT HAVE a fully featured FIRMWARE AVAILABLE. This board is not useful right now unless you are a programmer.

This board is untested. The top section should be largely identical to the A17DD-SO8.

This board requires a Power-SO8 footprint N-Channel FET such as PSMN3R0-30YLD. Something like AO4468 should also function if you have that laying around.

A simple pre-amplifier for guitar or bass with variable gain.

For use both with SMT or PTH resistors and capacitors, a power supply of +/- 5V up to +/- 15V (hint: an ATX power supply of any PC has +/- 12V), and a dual opamp such as NE5532, OPA1642, OP284, etc.
