mcHF V06 TX-RX relay antenna switching as implemented by Wolfram PY2BND
Related post: https://ea8arx.blogspot.com/2018/06/tx-rx-antenna-switching-pin-diodes-vs.html When I had to make the modification of my mcHF V06, due to the breakage of a pin diode in the antenna switching circuit, I forgot to document with photographs -step by step- the modifications that had to be made on the RF board. At the time I thought my explanations were enough. Although I was able to personally comment with Chris M0NKA on the modification I had to make as I did not have a replacement for the PIN diode quickly, I had no response from any other radio amateurs who would have carried out the modification. Until Wolfram Perrey, PY2BND, contacted me from Brazil asking for details of the implementation. In his case he wanted to carry it out to improve the transmission signal. Before continuing, I must add that Wolfram is a very qualified engineer who would not have needed my additional explanations to carry out the modification, but Wolfram had the idea ...
