Yes, the capacitors will need changed for proper operation in the 150.8 to 162 range. The helical resonators for the VHF MICOR were in 2 splits, where the receiver boards were in 4 splits. The helical resonators for the lower of the two splits (xxx1 and xxx2) covered from 132 - 150.8 MHz. The helical resonators for the upper two splits (xxx3 and xxx4) covered 150.8 to 174 MHz. The better thing to do would be to trade someone looking to do a 220 conversion. The xxx4 is the better receiver to start with when doing a 220 conversion. I'd bet with the recent 220 inquiries here there would be someone willing to swap you xxx3's for your xxx4's! Kevin
