![]() The Driver Bias out of specification is very common on the first.ĭon't let people say a set that is 15yrs old in design is a better radio - it truly is NOT. Adjusted the Driver Bias from 0.6V to the specified 0.5V. ![]() Receive current with lights off after 'light timer' setting timeout is 0.33 A Transmit current with lights off and 10 watts output is 2 A. Receive current with default settings is 0.55 A. Hi, I have one and they are really good they are 100% better than the noisy 706s that is replaced. Performance is faultless, does everything it says on the tin Would i consider getting rid of mine Patch Incredimail Premium here.only if an FT-9000 came along at a ridiculously low price Definately a keeper. So if you are buying new then you will have no problems, if you are buying used then just get a later model than the ones listed above. Apart from the above the sets have no others issues, and my info comes from a very good source at Icom. A simple cleanup of the blade fuses will correct this, but it will return over time unless you simply change the fusesholders for some good quality ones. Low output power- The output power drops significantly as the supply voltage drops, and the fuseholders in the power lead are well known for creating a bit of resistance, therefore lowering the supply voltage. 8Khz tone - Again a genuine problem, an 8khz tone could be heard in the rx audio, and again put right by Icom anything later than serial no 1001551 (2006) would have the B6250K logic board fitted in production, anything earlier would need checking. Serial numbers before this may have been back to Icom for the upgrade anyway, but still need checking. ![]() Blown finals - This was a problem in UK sets and needed an upgraded PA board, Sets later than serial no 1001601 ( April 2007 ) would be produced with the upgraded board as standard. When left on receive the fan will come on if needed, but this rarely happens on rx as the heat naturally dissipates as long as you have left adequate room around the set. There were problems in the earlier models, heres how to avoid them Overheating - This was never a problem, the 7000 does run quite warm, but no warmer than the 706 range The fan is thermostatic controlled, and does more than a good job of speeding up when needed, it only runs on tx, and if required it will run faster to exhaust the heat when needed. I hope i can help you on this one First of all you will probably read reviews of failures and overheating, going up in smoke etc. ![]()
