Icom (UK) Ltd will charge £50.00 plus VAT for the modification, this includes return carriage within the UK. It is the responsibility of the user to ensure they comply with the licensing requirements. Receivers may suffer from lack of sensitivity ATU’s will try to tune on frequencies for which they were not intended power amplifiers will not match correctly and may radiate spuriously or may even fail. Broad banding permits the equipment to transmit on frequencies that have not been tested. New in 2003 - 2004: Orion & IC-7800 Ten-Tec Orion & Icom IC-7800 Until the Orion came out, 99 of modern transceivers were up conversion radios. Radio equipment has a published specification and our equipment is guaranteed to meet and generally exceed its specifications. Icom do not recommend the general broad banding of radio equipment. The '65 Mustang 289 used to be way up high on lots of lists, in '65-66. But it's technologically old and it's slipped down the list quite a ways as newer designs have surpassed it. When some of the radios listed were designed, the allocations were not within the amateur band and therefore were never considered part of the design requirement. The IC-7800 was, at one time, towards the very top of the Sherwood Labs list. Great care should be taken when expanding the frequency ranges of any radio. Hardware modification available for 5.260 - 5.405MHzħMHz standard on UK version, 5MHz not recommendedħ - 7.2 standard with version 1.2 Firmware Hardware modification available for 7 - 7.3MHz That review should go down in history as a way to NOT write a review. I have tested have an ADC overload point 122 to 125 dB above receiver noise floor. The single worse review I ever read, outside of reviews in magazines that actually don't test the radios, was the IC-7800 review in QST. Hardware modification available for 6.9 - 7.5MHz Comparisons among Kenwood TS-990S, Icom IC-7300 and IC-7610 I don’t own a TS-990S now, as I gave it to my friend and repair genius N0QO, who got it. Hardware modification available for 5 - 5.5MHz

If the modification is carried out by Icom (UK) Ltd your warranty will not be affected.īand Expansion of transmitters on HF radios I have been able to test up to 1200 MHz and it sounds and receives great on everything I have tested. Due to the age of my radio I did have to replace the CRT but that is common with this radio.

It has great sensitivity and sounds great. Performance is not guaranteed on the 5MHz band. I have had this radio for several moths now and it is one of the best HF receivers I have ever owned. Additional transmit frequencies may be enabled and the band edge beeps may not reflect the UK band plan. Please note, that additional sections of the bands may also be affected by carrying out the expansion. I was very fortunate to be given the opportunity to try out the IC-7800 for a few days and this review presents my impressions. Below is a list of the radios that can be modified. Icom are pleased to announce details of those HF radios whose frequency ranges can be expanded to accommodate the changes to the 7MHz band and the allocation of frequencies with the 5MHz band.
