    :

    I am often traveling with my Ham Radio gear to various locations (business and leisure).

    Although I have been a loyal Heil customer for many years, I at once agreed to test the new ModMic Boom Microphone when Bjorn showed it to me some time ago.

    When finally getting a chance this weekend to try the mike out together with my TS 590S, I must admit I am impressed!

    Without asking any stations for a sound check, several stations spontaneously commented on the nice DX/Contest Audio.

    I did not even play around much with the TX-equalizer of my 590S, but at least managed to test the predefined positions. My voice in combination with ModMic suited the HB2 setting best. I will play a little more with the settings in the ARCP-590 program, but even without this fine-tuning, I can say this was one of my best buys ever.

    The reason is that I no longer have to bring extra headphones for my radio. I can use my Bose Noise-cancelling headphones and then just apply the small magnet with the self-adhesive sticker, place the microphone in the protective box and be sure that no damage will occur when traveling. This in addition to the fact that my Bose headphones are pretty much nicer to wear for 48 hours compared to a heavy Heil headset, makes me think I have beaten two flies (at least) with the same whip.

    Good stuff guys and I truly can recommend this product both for the fixed DX/Contest operator and for the weight concerned DX-expeditioner/

    PS I broke the pileup for E6GG on two bands with this nice audio, but actually with a small pistol signal using a Hex Beam at 6 meters and a kW. Somehow, the pitch of the mike helped me out and I got them om first call on 17 meters, and second call on 15!

    :

    After our successful dxpedition to Tromelin island FT4TA in 2014 we learned that each operator wanted to use his own headphones, some with active noise canceling. We all agreed at that we spent too much time by re-cabling the mic/phone plugs, and sometimes had to change microphone settings at each operator change.

    During preparations for the Juan de Nova island FT4JA DXpedition, I got introduced to the ModMic. It looked really interesting and potentially a way to overcome our previous headset cabling issues at FT4TA. I ordered one and after some days of testing it was decided that the ModMic would be used for for all SSB contacts of FT4JA.

    We briefed the 10 operators to bring their favorite headphones (mainly Bose QC noise cancelling and Beats models) and install the magnet base clasp to which the ModMic magnetically attach to, on to their headphones. Once this clasp is there, you can leave it forever because it is almost invisible.

    The ModMic was really a nice add-on to the DXpedition. At operator change, just grab the ModMic and move from one headphone to the other. In less than a second the new operator can start operating.

    At the end of the expedition, everyone agree it was a good idea to use the ModMic, and that we will for sure use them again at our next DXpedition.

    We strongly recommend anyone that want comfortable audio headphones but still want to enjoy SSB to consider the ModMic. FT4JA made more than 45000 SSB QSO, all of them with a ModMic, so for sure it works !!
