Icom proudly announces the debut of the new HF/50MHz transceiver IC-7410. The IC-7410 has been designed as an HF/50MHz specialized rig with excellent performance and features in this category. The IC-7410 employs high grade DSP unit and double conversion super-heterodyne system developed from the latest technology used in our higher grade rigs such as the IC-7800/7700/7600 series. In addition, the IC-7410 comes with a built-in 15kHz 1st IF filter and can accept up to two optional filters (3kHz/6kHz). When used with these 1st IF filters, narrow mode signals such as the CW and SSB modes are protected from adjacent strong signals.
The IC-7410 employs a much higher speed DSP unit compared to the IC-746PRO/7400's DSP unit. The AD/DA converter AK4620B allows for a high dynamic range and superior S/N ratio.
The IC-7410 employs a double conversion superheterodyne system which has an image rejection mixer for the 2nd mixer stage. When compared to a typical triple-conversion system, signal distortion is dramactically reduced.
Icom's analog RF circuit experience combined with the latest DSP software technology results in +30dBm IP3 equivalent to the IC-7600. Even in tough RF conditions, such as interference by broadcast stations or strong neighboring ham stations, a weak signal can be clearly received by the IC-7410.
The IC-7410 comes with a built-in 15kHz 1st IF filter and can accept up to two optional filters (3kHz FL-431 and 6kHz FL-430). By changing the first IF filter width according to the operating mode, the desired signal is protected from the influence of nearby strong stations. The 3kHz first IF filter is especially effective in the CW and SSB modes. (Fixed for 15kHz in FM mode.) * in 14MHz
A high stability TCXO crystal oscillator provides 0.5ppm of high frequency stability over a wide temperature range (0C to +50C). This allows for a long stable operating time in modes such as RTTY.
The display increases in width from the IC-746PRO/7400. The large multi-function LCD shows frequency, 9-character channel name, channel number, multi functional meter (includes S-meter, RF output, SWR and ALC level). The dot-matrix portion of the LCD shows the following items:
The built-in RTTY demodulator and decoder allows you to instantly read an RTTY message on the display. No external units or PC required. The built-in tuning indicator visually helps in critical tuning.
The internal antenna tuner covers from 1.8MHz to 54MHz and automatically tunes for low SWR. Variable capacitors provide higher accuracy than a typical mechanical relay tuner. Once you transmit on a frequency, the tuner can instantly retune the frequency using its built-in memory.
The IC-7410 has a standard type B USB connector and can be connected to a PC. Modulation input, audio output, RTTY demodulator output and CI-V command can be controlled via the USB cable. Also, the conventional CI-V remote control jack is built-in to the IC-7410. Download the USB Driver
When compared to the IC-746PRO/7400, the IC-7410's large heat sink improves heat dissipation. Even during long hours of heavy-duty cycle operation, the IC-7410 provides stable output power.
The optional RS-BA1 allows you to use the IC-7410 from another room using your home network or even from a remote location over the Internet. Most settings such as filter width, AGC constant, etc., can be controlled from your PC.
The screenshot shows the most-popular websites. Amazon.com is shown in blue because it moved up a notch that day. MSN.com is shown in red because it dropped below Amazon. The ranks of the top websites dont change very often, so thats why the Change column is mostly zeros. Lower-ranked websites have ranking changes almost every day.
I invented Rank-O-Matic to save time. Previously, I would enter my Alexa rank into a spreadsheet once a week. Then I would go to each of my competitors websites, get their Alexa rank, and enter those too. If a website moved up, or down, a notch, I had to re-order my list. But I kept finding more and more websites in my category, and my spreadsheet got bigger and bigger. Eventually, I was spending way too much time doing something that should be easier.
I also needed to collect my own data so that I could make a graph of my websites progress. Alexa.com makes graphs, but only if your ranking is better than 100,000. So, small, and up-and-coming websites need an alternative way to get a graph.
Now, with Rank-O-Matic, not only can I update all of my data, and make a graph, in a few seconds, but I can do it every day instead of once a week. I can quickly see how Im doing, and which of my competitors are sinking or rising.
If you operate a website, then you need Rank-O-Matic. And if you dont, you may find it useful anyway. For example, if you are an investor, you might want to monitor the rankings of your companies. For example, if you own stocks of retailers, you would want to know if one of them started to sink because that could indicate that they were losing market share.
Now, you will need to add some websites to your new category. You can do that with the Add Site command on the File menu, but it is easier to just drag-and-drop from your web browser. Most browsers have a little icon next to the URL. Here is a picture showing the upper-left corner of Googles Chrome browser. The red arrow points to the URL icon:
If you drag-and-drop that icon onto Rank-O-Matic, it will add the site. Then you can double-click on the site to edit the name, add a note, etc. Make sure to drop the icon onto the part of screen where Rank-O-Matic lists the websites.
Once you have your websites set-up, you are done for the day. Tomorrow, run the program and click the Update button, to fetch the new ranks. Alexa updates rankings on a daily basis, so once you click Update, the button will be disabled until the next day.
The graph feature wont be useful until you have collected a few days of data. If you want to make fancier graphs, go onto the File menu and then to Export Site Data. Save the file, and then open it with a program like Excel.
Update Errors While the Alexa API is very reliable, sometimes it will return an error, or fail to respond. When that happens, you might see something weird for a websites rank, such as 999,999,999. To fix it, click on the website, go onto the File menu, and then to Update One Site. You should then get a normal rank; but if not, try it again later.
PDS is available in three capacities/sizes: 10 cubic inch capacity with a 1 NPT process connection, 50 cubic inch capacity with a 2 NPT process connection, and 180 cubic inch capacity with a 3 NPT process connection. Body materials are choice of Geon PVC, CPVC, Natural Polypropylene, or Kynar PVDF. Inlet screen and dome top match selected body material. Bladder material is EPDM or FKM. Air inlet valve and gauge isolation valve (non-wetted) are brass. Fasteners are stainless steel.
Pulsation Dampener and Surge Suppressor will steady a pulsing flow caused by diaphragm pumps, piston pumps, peristaltic pumps and other quick flow interrupting equipment. The PDS will steady a vibrating pointer of a pressure gage or flow meter under flowing conditions. When used properly, quick pulsating flows will be greatly reduced preventing the following flow control problems:
Pulsation dampening provides the added benefit of smoothing the output supplied by many types of pumps, especially double diaphragm pumps and metering pumps. This provides a steady, uninterrupted supply to points of use, which will greatly enhance system productivity, prolong pump life, and prevent splashing and foaming.
Water Hammer Arrestor When used properly, water hammer will be greatly reduced to just a few percentage points of the spike that the system would have without using the PDS. This helps prevent the following flow control problems, as per the Plumbing and Drainage Institute Standard PDI-WH 201:
Inlet Stabilizer AKA Suction Stabilizer Installed as close as possible to the pump inlet, the PDS will take in liquid when the system is pressurized. If the dome is properly charged with compressed air, the PDS will expel the liquid back into the pipeline when the pump draws liquid and pressure drops. This repeated action ensures a continuous supply of liquid to the pump, reducing strain on the pump and greatly improving pump efficiency. Used in combination with a PDS on the discharge, in most cases the pump will supply a smooth, steady flow at a constant pressure and prevent the following pump related problems:
Accumulator As with the inlet stabilizer function above, the PDS will take in liquid when the system is pressurized. If the dome is properly charged with compressed air, the PDS will expel the liquid back into the pipeline when pressure drops. This cycle is automatic, or the liquid and line pressure can be retained and released as needed simply by using a blocking valve between the PDS and the piping tee. The accumulated liquid and pressure could be held for unexpected power outtages or other system failures, and then used to complete a cycle, retained for backflush during scheduled maintenance, or any other requirements when the regular process is off or interrupted. When the intended use of the PDS is solely as an accumulator, the blocking valve need not be a full port design.
Thermal Expansion Tank Liquid temperature generally increases in a flowing condition. It can also increase due to processes or external factors that transfer heat to the media. When temperature increases and liquid which is non-compressible expands in a closed system, the results can be catastrophic. The PDS can be used as a simple expansion tank in many applications where anticipated expansion would be less than the stated capacity of the unit.
Important: Please note that Series PDS is designed to operate as a pressurized vessel. Proper precaution should be taken to ensure safe installation and operation; read the installation instructions carefully prior to use. The unit should be charged with regulated compressed air or nitrogen only. Oxygen must not be used. The gauge isolation valve should be closed prior to opening the system connection valve. Failure to observe all precautions could result in system failure, leaks, explosion, property damage, personal injury and/or fatalities.
For FKM seals, use V for example PDS010VT-PV; for EPDM seals use EP as shown above. Standard connections are threaded and indicated by the T after the seal material. For CPVC body, use -CP for example PDS010VT-CP; for Natural Polypro use -PP, for Kynar PVDF use -PF. For PVC body use -PV as shown above. For optional gauges, connections or materials please consult factory.
PDS for pulsation dampening may be determined by the type of pump, pump volume, etc. and PDS for water hammer arrest may be determined by pipe size, flow rate, etc. as shown on the following selection tables.
The suitability of the PDS as defined by the following tables may not be appropriate for every application for a variety of factors, including but not limited to liquid velocity, presence of entrained air or gas in the pipeline, distance from pump or quick closing valves, specific gravity and/or liquid viscosity, temperature, variances in pressure, and a host of other factors. For applications in question, please use the formula shown above.
As a general rule, the charts below will eliminate about 75% of pump pulsation. The formula above solves for a higher capacity than those listed in the charts, and will eliminate about 98% of typical pulsation in the same system.
NOTE: Please remember that the user is ultimately responsible for the suitability of a PDS Dampener for any given application. An improperly specified or installed dampener can result in leaks, fugitive emissions, explosion, catastrophic failure, property damage, injury or death.
The sizing charts provided are general guidelines. If the dampening in a particular system is not sufficient, an additional or larger unit may be required to meet the requirements of a particular system. POM dampeners, water hammer arrestors, and inlet stabilizers have inlet ports larger than other competitors to transfer fluid and forces faster. This allows slightly smaller and lighter units to be used as opposed to larger and heavier ones.
There are many different locations within a pipeline where pulsation dampeners/surge suppressors/suction stabilizers etc. should be installed. In all cases a blocking valve should be installed between the PDS unit and the piping tee. If the PDS is to be used solely as an accumulator, the blocking valve can be a reduced port or throttling design if desired. For all other uses the blocking valve should be a full port design such as a ball valve. The installation tee should be one pipe size larger than the system to facilitate pressure transfer. Generally speaking, the PDS should be installed as close as possible to the application need. In other words, an inlet (suction) stabilizer should be near the inlet of the pump. A pulsation dampener should be near the outlet of the pump. A water hammer arrestor should be near any quick-closing valves. As an expansion tank, the PDS should be close to the source of temperature increase.Get in Touch with Mechanic
