+SMD components are a reality in electronic gear since at least 15 years. Refusing to use SMD would mean refusing to accept reality. Soldering SMD components is quite different from soldering wired components. But soldering SMD is by far "impossible". SMD soldering may seem difficult at first. It is quite feasable to do SMD soldering with standard soldering tools that you may have already. Please find below some general hints on SMD soldering that you may try before starting to solder your mchf or OVI40. Better to know the SMD soldering basics in advance than to have to make tedious soldering corrections later...

 ===== Detailed photos =====
 One picture says it all - The following photos show the fully populated UHSDR I40 UI pcb.:

 The UI pcb can, and of course should be, tested first before connecting it with any RF board. (I40 UI is fully compatible to the original mcHF RF board versions.)
 The LCD panel should be left off here as well and jumper P6 needs to be bridged.
-Connect pin 30 of the connector strip with ground and pin 28 with +5V. The actual current should be clearly under 80mA !

 If not, supply voltage should be removed immediately and the pcb be checked for possible errors.
 If all is fine, connect the small USB connector to a PC.
-Under Windows OS you instantly hear the typical chime for new USB components and the taskbar shows an //STM in DFU mode// in the information bubble. Linux is a bit more "silent" here.

 Its the same way as its done with the originally mcHF UI board.

 If this was all successfully completed, then remove the supply voltage and also remove jumper P6. Put the LCD panel into its connectors and reconnect the +5V voltage to pin 28.
 You should now see the boot process with the UHSDR bootscreen and some error messages. These messages are expected, cause of the missing RF board.
