I can only indirectly compare using the 990S to the 7610 byĬomparing the 990S to the 7300, and then the 7300 to the 7610. The W1BB contest was more of a pile-up test than theĪRRL 10m event, which mostly dealt with copying very weak signals. Level in the W1BB contest was not as high as in the very popular ARRL 160m CW contest, the new 7610 performed very well separating stations. It resulted in my second best score in this contest, being only a few percentage points behind my results in 2009. I also operated the 7610 during the Stew Perry W1BB CW Top BandĬontest on December 30 th. Weak, even with a 5-element monoband Yagi at 65 feet. Sunday I had other commitments, and as it turned out 10m conditions were even worse on Sunday than Saturday. I used the 7610 at the third operating position with the Acom 1000, which had no rig setup at Ops3 at thatĬonditions were very poor, and I only had 37 SSB contacts andĨ8 CW between Friday night and Saturday. Ops 2 (IC-7300 + Alpha 89) to hook up the 7610 for the 10m contest. With the 7610 arriving at the last minute, there was no way I had time to tear down Ops1 (IC-781 + Alpha 99) or I am sure the 7610 will also be great with the Alpha 89, but I haven’t run those together yet.įor the ARRL 10m contest I had the 7610 at Ops3 with the Acomġ000, which isn’t a slouch on QSK either, but it is vacuum relay, not PIN diode. Eventually I’ll have the 7610 hooked up to my Alpha 89, which like the 87A, has PIN diode T/R switching. Switching, and thus QSK is excellent on both the 990S and the 7610. The TS-990S and IC-7610 have the same type of solid-state T/R On the other hand, NR on the Kenwood was useless. I ran the 7300 NR on 3 out 10 most of the time, and that evenįurther reduced band noise annoyance. Occasionally I had to turn up the AF gain on a weak 160m CW signal, but in return band noise fatigue was minimal. Put band noise 8 to 10 dB below AGC threshold. Since I was going back and forth between the 990S and 7300, I set the Kenwood to 18 dB attenuation and the IC-7300 to 20 dB, its only choice aside from the RF gain. On 160m I used significant attenuation to get band noise belowĪGC threshold. Selectivity isĮxcellent, Icom NR (noise reduction) is the best I have ever used, and ergonomics are particularly good on the larger 7610. Aside from QSK and APF, the two Icoms work about the same. It goes without saying that the larger 7610 has advantages due to its size. Let’s ignore the bigger size, bigger screen, more buttons and Some split operation exits on 40m, butĭuring October 2017 CQWW SSB, I worked only one SSB station split on 40m.

Of course dual watch (dual receivers) is important for DXpeditions, but of little significance most of the time. The big improvement between the 7300 and the 7610

Due to awful conditions, except for a brief E skip opening on SSB to Washington state in particular, most of my time was spent on CW. My 7610 arrived just in time for the December 2017 ARRL 10mĬontest. Since Ken is moving QTHs, and has no towers/antennas yet, I used the TS-990S during ARRL 160 CW contest in December 2017 along with my IC-7300.

(For those who don’t know, a very near lighting strike EMP took out my 990S in 2015.) After 40+ hours of troubleshooting and repair, and $500 in Genius N0QO, who got it working perfectly again. I don’t own a TS-990S now, as I gave it to my friend and repair
