ICOM monitoring scope or panadaptor
Hi,
If ICOM ever produced one of the subject items to go with the ICOM R-71A receiver or some similar equipment, I would appreciate knowing the model number so that I may find out the RF input requirements. I am trying to ascertain the specified output level from the 'scope' socket (70.4515MHz) of one of these receivers but neither the workshop or operator's manual mentions it. Measurements show that it is quite low, just as an inspection of the schematic might suggest, but there is still a nagging doubt that the receiver is not quite up to specification as the antenna to scope socket loss is around 30dB. IA - Joe |

But I seem to remember your measurement is quite right. that output is quite low. Icom never produced a monitoring scope. Others did, There was a company in atlanta that did produce a scope that used that port however it was far more popular with the R-7000.
