1. IC91AD Programming

2. There are several ways to store information into the IC91. You can manually write channel information using the front panel. This is very tedious and error prone and not recommended unless you just want to store one or two channels. Icom offers their copyrighted RS91 Cloning Software that uses a simple cable and PC interface. Dan Smith, KK7DS offers a free to download cloning package called CHIRP that uses the same cable as the RS91 package.

5. IC91AD - Manual Programming Band - A Chapter 4 in your IC91AD user manual outlines manual programming. The IC91 is divided into two bands or VFOs, A and B, or Main and Sub Band. The A Band contains 800 Memory Channels that may be divided into 26 Banks. The A Band supports FM (20 kHz. channels), WFM (Wide FM 150 kHz channels) and AM, receiving from 495 kHz to 999.990 mHz. - NOTE – NO DSTAR in the A BAND. Transmit is limited to FCC Band Allocations.

6. IC91AD - Manual Programming Band - B The B Band contains 400 Memory Channels that may be divided into 26 Banks. The B Band supports FM (20 kHz. channels), NFM (Narrow FM 12.5 kHz. channels) AM and DV (DSTAR), receiving two segments from 118 mHz. to 174 mHz. and 370 mHz. To 470 mHz. NOTE - DSTAR is in the B BAND only. Transmit is limited to FCC Band Allocations.

7. IC-91 Keyboard Press buttons on the face of the IC-91 do multiple tasks. Each key has two or three different labels. The RED labels indicate pressing momentarily.

59. IC-91 – How I use the radio page 1 There are many features in the IC-91 and every user has different purposes for the radio. I am primarily a local, one repeater user who likes to /route to different repeaters and use the reflectors, and /route to the JA repeaters.

60. IC-91 – How I use the radio page 2 I use the A sub-band for FM and various frequencies that I like to monitor – I have very few entries in the A sub-band. The B sub band is broken into several banks, each containing different /routes to reach the various repeaters in the DSTAR network.

61. IC-91 – How I use the radio page 3 I keep call channels C0 and C1 for 2M and 70CM local / reflector use with the gateway enabled. UR=CQCQCQ, R1=K5CTX B or C, R2=K5CTX G, and MY=NU5D. The TX Message is UR=K5CTX B to let DX stations know how to reply to a call. This is useful talking to JA stations.

62. IC-91 – How I use the radio page 4 The banks are America, A, B, and C, D for Deutchland, E for Europe except DE, IT, and UK, G for Reflector Links, H for Call Home From, I for Italy, J for JA, N for Name or Call Sign Routing, U for UK, and V for VK. I use the VFO to quickly program stuff that is not kept in memory. The MENU lets you quickly program the UR and Message/Pos lets you see the message from a prior caller in case you missed the first pass.

63. IC-91 – How I use the radio page 5. Before making a call I go to the G bank and check STAT to see if the repeater is linked to a reflector or another repeater – You cannot tell what you are linked to (YET) but you can tell if you are linked to something. If linked I either UNLK or press CALL to make a reflector call. If I unlink then I choose who I want to call using the different banks and memories.

64. IC-91 – How I use the radio page 6. This covers most of the basic stuff. Don't be afraid the experiment and make a few calls. 73, Steve NU5D
