Heil and the IC-7000
 All of Heil's products built for the 706 will work well with the Icom IC-7000. The Traveler 706, the iCM with the HSTA 706 adapter and the favorite is the HM-iC HANDI MIC with the Ch-1 iM cable. For the ultimate headset operation any of our IC headsets (BM-10 IC, PRO SET IC, PRO SET PLUS IC, PSQP IC) with the AD-1iCM modular adapter.

 Set the Transmit bandwidth in the WIDE position 200 Hz and 2900Hz. For extreme articulation, contest or DX pileups ups use the MID or narrow bandwidth filters.

 The IC-7000 has extreme audio capabilities. At the Heil lab they have been VERY successful in using the 8 band W2IHY EQ into pins 2 and 11 of the rear accessory socket. Using the PR-40 with this setup absolutely stunning. Transmit Bandwidth set at 100 Hz and 2900 Hz.


HC-5 on the IC-7000
 Because of the lack of mid range and high frequency articulation in the IC-7000, you will discover that the HC-5 will give you the best results.

 You will have to set it up correctly.
  • COMPRESSION On all the time. Set to 4
  • MIC GAIN sets about 50% - or where the ALC meter is happy
  • WIDE transmit filter set at 200Hz and 2900 Hz.
 This is actually giving the best results as the HC-5 ads such wonderful articulation. I am using the HM-5 Handi Mic with the CH-1 IM modular coil cable for the 7000. You could use the HM-10-5, the GOLDLINE GM-5 or any of the headsets using the HC-5.

 The key to getting decent audio is to set the IC-7000 low end at 200 Hz. and 2900Hz on the top. There seems to be some weird anomaly with the mic pre amp section that when hit with lots of low frequency energy from the microphone, the transmitter gets "hollow' or boxy sounding. Moving the transmit bandwidth filter to 200 Hz. (not 100 ) seems to solve a bit of that. The HC-5 helps more as it doesn't start up until 300Hz so it is a perfect match for the IC-7000.

 When the compressor is used at the low level of 3 or 4 it acts as an additional microphone pre amp. Just what is needed when using low level dynamic elements such as the HC-5. It truly has been the best combination so far.
