IARU Oktober UHF CONTEST PI4GN and Microham Keyer2 with IC706

 PI4GN 432MHz result   I was operator  Saturday.  Propagation  poor, a rain front was blocking UK. PI4GN was on 70 23 13 9 6 3 1.56 cm active despite bad weather we did reach very good distances on the UHF SHF bands

PI4GN 432 result IARU October 2021

 

My home 23cm was deaf no beacons  PI4GN local  signal was only s9 max rainwater intruded  in the slot dipole dish radiator but after i drained it receiving seems normal again, left a small opening in the bottom slot  top closed with tape SWR was back to normal no further damage done i hope

 

Micro KEYER2  with IC706

 The IC706 PA T/R timing sequence issue is solved by the Microham micro KEYER2 

The microphone is muted in digimode and i got rid of the external USB Audio QRM at VHF /UHF 

The number of cables is drastically  reduced .   The old IC706 is working well together with the home made 200W 144 PA QSK mode without Antenna switching issues !

Without the MK2 i could not use the PA in phone mode since the IC706  RF pulse at R/T activated the SWR >3 protection circuit

I got this MK2 2nd hand together with an IC8 interface cable.  For the IC706 i made my own cable, that is: the 37pole  split up to the IC706 rj45 microphone , the 13pole ACC ,the CI-V. Foot-switch, PTT out and key-paddle are plugged in at the back of the MK2.

These cables are relative expensive but after making one i know why . 

All is working fine the only missing thing is a separate connection for a straight key.

The performance hard and software  is  top quality,  very well done by Microham.

this Keyer and cables all replaced by the Micro Keyer2 !
