You may also select HB2 (High Boost 2) if youre using a wide-range microphone, like the PR 781, on the TS-590. And I dare say, microphone gain is the one control on modern transceivers, almost no one gets right! In the 1990's, when the equalizer rigs started to appear, it became apparent many SSB signals could be copied on the diode (AM) detector. I ultimately traced it to the headset's mic cable having inadequate shielding (spiral-wrapped fine stranded wire that provided perhaps 70% coverage instead of a braided or aluminized mylar shield). If you set this first filter frequency to 200Hz. On the GM-4 and GM-5, use only the Narrow element, as the Wide element has too much bass response for this rig. Investing in outboard gear has become common place. NOW - DO NOT FORGET TO SAVE these by holding the menu button for 3 seconds. Menu 83 : 3000 (TX bandwidth) .

Sincerely 73 de Clinton Herbert, AB7RG. This will roll off some of the extreme low frequency response. Cutting these frequencies will reduce intelligibility. No apparent reason but it is true. Finally, if you have the ability to select the SSB bandwidth of the monitor receiver, set it as wide as possible. 'Bandwidth' control set to a wider setting (say 10), the filter will encompass the audio frequencies from about 100 Hz to 400 Hz. To use any dynamic element on these phantom-powered inputs (which should NEVER be applied to the mic input of a radio transmitter, IMHO), the input must be de-coupled so the mic audio AC signal can pass through to the mic preamp, while simultaneously blocking the DC voltage from reaching that mic element. 63 +6. The Elecraft operation manuals are the best in the business and we highly recommend you read them thoroughly before making any adjustments or operating the transceivers. Third, are the modern designs: 746Pro, 756Pro series, iC-7600, 7700, and 7800. I spoke into the mike at a normal voice level from about 6 inches away. Set the SSB TX Bandwidth to 200-2800 Hz for high-fidelity rag-chews, or to 400-2600 Hz for DX work. We have notched some low end out by setting the transmit bandwidth in the beginning then with the EQ, we reduced some low end (menu 091) and this is always a major problem. Why buy a PR series mic if you are going to restrict the bandwidth from 200-2800 then roll off all the lows? The K3 includes a versatile 8-band transmit equalizer, which is adjusted separately from the receiver equalizer. When using a dynamic element on rigs like iCOMs, which were designed for electret microphone elements, one must not be afraid to do two things: (1) utilize the full range of Mic Gain available, and (2) turn on the Compression, using the Compression Level control as a secondary Mic Gain control if necessary. Thanks to GM0ONX for this drawing. Last, Heil's cables contain a small jumper wire from mic shield pin of the connector to the shell of the mic. I use these settings and it sounds very good i l. AMC level: 55. There will be three important frequencies to attend to. AM-TX-Bandwidth (TX BPF SEL) 100-2900. The Heil iCM is the perfect and best match to this iCOM model. The only sure way of see your over the air audio response is with a receiver that has an accurate spectrum analyzer display. Basically, there are three ranges (low, Mid, and High) for equalization; you can roll off any one of these, peak any one of these, or peak one and roll off another.For DX and Contest work, use selection 9 (this rolls off lows and peaks highs). Back to the radio. ThePRO 7-iChas the appropriate cable included and will sound wonderful with a 7300.
