Hi Barry,
I have built a GoBox for my MTR3B based on a Peli 1040 case, which is ultra-robust and watertight. The details of that project are described here: The 1 Kilo HF challenge. A multiband activation pack below 1 kilogram - #99 by DK3IT
Now, I am working on a new version for my MTR5B. The solution will incorporate
- the TinySWR meter
- an AF amplifier and control monitor
- volume control
- 4.8V/2400mA NimH battery + step-up-converter that can create 6 / 9 / 12 V for 1 / 2.5 / 5 W
- rotary dial for frequency and cw speed
- undervoltage indicator
- zero beat indicator
- LDO 2.7 V for buffering the RTC (instead of the faulty coin cell)
- a Pico Single Paddle
I will post all files online as open hardware, but it will take me some more weeks to finalize this.
Because the MTR5 is bigger than the MTR3, the circuits will only fit in thanks to a small double-sided SMD PCB, which I already have on my desk. You will be able to order it via OSH Park for a few dollars.
