Kees K5BCQ has designed a standalone Power and SWR Meter based on AD8307 chips for a standalone OLED and Arduino Nano. This could be added in to any QRP rig including the µBITx or a BITx40.
Kees K5BCQ has now provided installation pics for his AGC kit. Kees has sold 100’s of these, and the installation concept is worth pursuing for a tidy install on your main µBITx board.
Details for ordering his AGC and Audio Pop Fix boards can be found under his call sign in the files section of the BITX20 IO Groups list.
Kees K5BCQs has 403 paid orders for AGC and/or Anti-pop Mini-Kits and 399 of these have been shipped. He has additional boards and parts and will continue to supply these Mini-Kits as long as there is demand. Details are in the “Files” section of the BITX20 webpage under his call K5BCQ.
Kees was somewhat surprised to be able to process such a quantity over a short period of time. That indicates there are opportunities for others to join in with their ideas. As Kees notes, the uBITX is a great vehicle for modifying and improving.
The list of potential orders for Keys K5BCQ on 3 May is surprisingly high (250+). Email Keys K5BCQ(at)ARRL.net (to keep from overloading this “topic”) and he’ll update the spreadsheet to include or amend your order.
Would you would like to have fixes in your µBITx for the audio pop and the missing AGC issues?
There are now two proven designs to the audio pop and AGC issues from:
- VA7AT for the audio pop problem
- ND6T for an effective AGC
Kees K5BCQ is taking orders now for two small PCBs to make it easier for constructors to complete these fixes. The PCBs require the use of surface mount components. They are tiny (about 1″ square) and can easily be mounted in any case. They will be very cheap and available both in the US and DX.
