N4PY Icom Control Program Version 3.27 Personal Computer This program is a 32 bit windows program. Your personal computer is an integral part of the your transceiver. The new updates provide CI-V commands for antenna control, logging software and RIT for this model. Release E4 of the IC-7100 firmware and Ver. 1.10 of the CS-7100 cloning software can be downloaded from the following URL from the Icom Inc website: www.icom.co.jp/world/support/download/firm.

Simple Icom CI-V Interface G3VGR Icom CI-V Interface Icom appears to delight in charging outrageous prices for all transceiver accessories, so many Hams improvise instead. A few circuits have been published for CI-V interfaces, most of which use the MAX232 IC. Drivers Gemini First Mix Pro With Vdj there. Here is a very simple CI-V interface, originally described. I've made small changes to the modem control signals connections. Although the circuit doesn't conform exactly to the RS-232 specification, it does work well and has the advantage of being easily constructed inside a 9 pin D-type shell.

Please note that the resistor value 4K7 means 4700 ohms. The transistor types are not critical, I just happen to have plenty of 2N2222As. I've used this interface on various PC's and also Dell Latitude Notebooks with both an IC735 and IC706MkIIG. No problems have been experienced even at 19200 baud with the IC706. It has also worked successfully when using a USB/Serial adapter from a notebook. If a PTT function is required from the COM port, pin 7 (RTS) can be used to provide this facility. The circuit is powered by DTR (pin4). I experienced some problems with YPLog using this power source.

If YPLog is configured to use PTT from either the Parallel port or a different serial port from the one used by the CI-V Interface, the program drops the DTR signal, resulting in no power to the interface. This is easily resolved by powering the circuit from RTS (pin 7) instead of DTR (pin4). To test and/or debug the interface, I would strongly recommend using program. I have also used this interface to program my Yaesu FT50R. Only a change of connector to a 4 pole minijack plug was required.

Probably the interface can be used with other HTs, although I have not tried it. Note: If you intend using this interface with a USB/Serial adapter, beware of a possible issue with many of the cheap adapters available on eBay. Many of these use counterfeit Prolific PL2303 chips. When Prolific discovered this, they amended their drivers to detect counterfeits. The drivers supplied with Windows7 & Windows8 will result in an 'Error 10' when they detect the counterfeit chip.

The workaround is to use the drivers supplied for Vista. Although I have successfully used the interface with a serial-USB adapter, I have seen USB CI-V cables from China at very cheap prices on eBay. Consequently, if your PC/Laptop has no serial ports, it's hardly worth the effort of building this interface nowadays. So just get a USB interface from eBay.

Disclaimer: Although I have tested and used the above circuit on my own IC735 and IC706mkIIG with no problems, I do not make any representation or guarantee that this circuit will function, nor do I accept any responsibility whatsoever for any damage or malfunction arising from the use of this circuit.

20 Jan 2016: V1.1.0.6 now available. Mainly fixes of R9100 settings plus a few labels that were missing from the earlier versions. 14 Jan 2016: New version 1.1.0.4 solves the floating point error issue and memory access errors in the IC-9100. Thanks to Duarte CT1EIZ who gave me the hint, the issue was caused because some countries use a ',' (comma) separator where we in Australia use a '.' (fullstop) as a separator character in our decimal numbers.

Also, Duarte uses an IC-9100 and had issues with retrieving & storing memories in it so sent a couple of screen shots for me to check since I don't have a 9100 to try the software with. I found that the 9100 was getting a 2-number memory channel detail where it required four. I have added a variable named Memchars into RadioModels.txt against each model listed. The likes of the 9100 (and similar) require this set to 4 while any others will likely require a zero (0) value.

The best idea is to install V1.1.0.4 dated 19 January 2016 into a new folder so that it will create new extracts of the support files, including RadioModels.txt. The Membanks value for a typical 9100 is 3. The other possibility is that the memory structure of the product does not match up with those set up in the matching model profile in the RADIOMODELS.TXT file. The details listed there were extracted from the available info at the time and it is possible that they are in error.

The best approach is to use the IcomExplorer utility and zip/compress the resulting data files and email them to me so I can see where they do not match up. The EXE file is in the IcomExplorer.zip available from the box below. This utility is very basic and there is no explanatory texts, try the 'seat of the pants' approach and grab whatever data files it produces. Click on the Write To File box to create disk files, use the Basic Test and Autotest buttons to gain further data.

Make sure you use the Read Mem#1 function so that the memory structure is downloaded. If Transceive is set OFF in the CIV configuration menu in the radio then nothing will be seen from the radio as it needs some response before it can figure out the radio’s address. 2nd April 2015: A new utility has been added to confirm that this style of software can actually access the windows registry and is not inhibited by antivirus, spyware etc applications running on the PC. A number of users report MESSAGES APPEAR SUGGESTING DELETING CIVLIST.TXT AND RADIOMODELS.TXT and I have not been able to duplicate the effect on any of my PCs.

This utility creates and reads a new key under HKCU/VK4ADC to confirm that access is permitted and leaves the key there after completion, it being the same registry area that the Icom MEMS saves its data into the registry. If it can't run correctly then there is no chance that the MEMS software will run either. MEMS.EXE Version 1.1.0.3 was also released today and it has two new functions to help solve the issues with previously untested models or with either very slow or very fast PCs.

The later models products are all included in the ' memstructure = 1 format and a new tickbox appears in this mode and it has the caption Adjust R/W Timing. Placing a tick in this box reveals a slider adjustment, a numerical value box and a SET button.

The standard values displayed there are typically 50 and this is representative of the rate at which the radio's memories are either read or written. Fast or slow PCs may mean that this value will require adjustment up or down to provide correct functionality. Instruction Manual Culinare Rocket Chef Manual. Note that the slider only makes an obvious difference during the memory read and write functions i.e. When the Read From Radio or Write To Radio buttons have been pressed. The values for read and write are actually separate even though they are shown on the same slider.

It is important that the SET button is pushed once the slider is adjusted and before the read or write to memories function actually finishes. It then sets the values in the Windows Registry for the next time. If you do alter the values and you still have problems reading or writing memories, exit and restart the software so that the altered values are preloaded. Values that are either too high or too low will result in rubbish to/from the radio and if in doubt, set it back to the 50 value. The second function is an I/O Debug tick box which, when selected, makes a window appear over the top of the grid data and it reflects the serial I/O taking place with the Icom product.

A Clear Window button appears below the tick box to allow you to delete old info if the screen becomes too full or conflicting. A few diagnostic text files are also created during the software operation while the I/O box is ticked and this allows the data exchanges to be examined in other than real-time, e.g. By me if someone has issues with a new model as the files can be emailed to me for further examination. The main info to look for in the onscreen box is any lines that start BAD: as that means that the command was rejected by the Icom product.

Either the function is not directly supported by the radio or the command has not been correctly formed for that particular model and requires either alteration of the RADIOMODELS.TXT file or a program alteration. The help file has not been altered for this release.
