    Thanks for sharing, one to keep in mind for other applications too. Sadly, many of the Prolifics chipsets are fake. Usually the cheaper ones on offer, and applications are getting good at identifying these and preventing them from being used. Kind regards, Phil

    Most cable modems now have built in routers. I can connect to my internet either using either wireless via the computer's, tablet's and phone's built-in WiFi or via Cat 5 or 6 cable as I have done to my Blu-Ray player. The last thing in the world I would ever do is distribute my internet vial the power lines. One failure in the plug and you've got 115 VAC running back through your cable to your computer.

    Good evening everyone, This might be old information to some but its new to me so I thought I would post as it might save someone else a big headache. I really like the Ham Radio Deluxe software and had been using version 5.24.0.38. I also down loaded the latest version 6 to trial with the intention of buying. I am using HRD to control my Yaesu FT-450D using a USB to serial adaptor plugged into the radio CAT interface. I have been struggling with software stability. The rig control would run for some random length of time 5-20 mins an then lockup usually taking out the COM port requiring a PC reboot - very very annoying. Anyway I raised support tickets with HRD in the US and after a bit of back and forth they asked me about my USB to serial adaptor which in my case had the Prolific chip set. Essentially they said they have had all sorts of trouble with this type of adaptor specifically the Prolific chip set. They recommended using either FTDI or Silicon Labs chip sets.

    Hello David, I think there are boards available commercially already : https://www.sdrplay.com/panadapter-if-interface-boards-available-from-kd2c/ These are being produced by KD2C and are supplied built. The boards are shipped out of the US and so for me including postage they are more expensive compared to making one as I already had the parts and tools. As KD2C is selling these I would not start selling myself but might make one up for someone if they are really stuck and can't buy one. Cheers & 73s, Dave

    Hi Dave, Thank you for sharing this which I found it very interesting, I’ve been looking for an alternative solution since the passing of G4HUP. Is this something you would consider manufacturing your version of Yaesu FT-450D IF tap? Because this is something I would consider purchasing. Thanks anyway.

    What would happen if you embedded a long wire on top of the rubberized roof of your coach and used an antenna tuner. I have a 37' coach and it usually is not stationary so I'm trying to come up with something that I can use while moving (not driving) and doesn't require setup time. I haven't tried this yet but it would be like a 90' horizontal loop. Van

    I will be following your thread hoping to learn something about antennas to use on my class a coach. Two items I am contemplating and will appreciate your comments. Firstly is a hinged antenna bracket with a 90 degree angle bar to raise the antenna, securing the angle bar to the ladder when antenna is raised. The other concept I've had is to embed a 80' wire looped on top of the rubberized roof and connect it to a remote antenna tuner like the Icom AH-4. My coach is generally not stationary.

    A couple of other factors you may want to check just to make sure that both of you are on the same page. First is to make sure both radios are set to High power. Second is to verify that your antenna mounts in both radios are solid. Baofeng's seem to have problem of the antenna mount not being tightened completely from the factory. This problem does not show up with the factory rubber duckie because the base is in solid contact with the case. When you change to the Nagoya 771 within a short time the loose mount shows up. Simply holding the portable tightly in your hand and swinging the antenna from side to side will show if the problem exists. Of course its an easy fix by using needle nose pliers to fit into the slots and tighten. Careful not to put too much strength into the process. Lastly verify you truly have a Nagoya 771 and not the knock-off that is out there. Rather than me going into that here simply do a search since there are several articles on the real thing vs. the knock-off and they...

    I have both a UV-5R and BF-8FHP and utilized the free CHIRP programming software and easily added all the NOAA frequencies into memory. I have never seen any "special channels" or reserved areas in either radio. A word of caution; the software automatically programs your radio to transmit on any frequency you enter at the radio's highest power. Alas, there is no way to turn the power to 0 or receive only so make sure you program these frequencies to the low 1 watt power setting. A point to remember is if you do program these frequencies in your radio then you can forget about ever using the scan feature ever again because it will get to the weather and stop. Of course you can restart scanning and it will scan all the channels until it gets back to the weather and will stop again.

    These devices were designed quite poorly from every perspective apart from the internet part - which works quite well. In my house I tried one, and it did mean that on the 'short-wave' bands there was a lot of horrible noises, what decided it for me was that it performed worse than ordinary wifi! It isn't supposed to, but it did. Network cables seem the fastest and most reliable, wifi connection with dongles in the PCs came second, and the mains wiring connection was early worst. A bit of investigation suggests that my neighbours, on the same phase of the mains have a mains fed baby alarm of some sort, and there's very low level internet data on the line suggesting other neighbours may have similar things going on. There's also a chance that if you have any ham neighbours, your data could be compromised by their activity - and you'd probably not notice, just experience sudden slow speeds and the occasional dropout of service.

    Hi Dan, On the SDRPlay web-site there are very useful single page spec sheets associated with each of the available units so it is quite easy to compare the functionality. In the UK the RSP1A is £99 ($133) and the RSP2 is £130 ($175) which I think is an excellent price considering what functionality you get for your money. Thanks for the digital speech link I will definitely check that out and am going to have a crack at FT-8 this evening if the band is behaving. I have been to the Tattoo in Edinburgh, my wife is Scottish. We found a very nice old Scottish whisky bar afterwards and I don't remember much after that :) It was raining that day to - rains a lot up in that neck of the woods. The weather is always unpredictable in the UK especially where I am over in the west. It can be lovely in the morning, raining at lunchtime and snowing by tea time. Just get used to it really - I was on a business trip to California earlier in the year and it just seems to be sunny all the time which was weird. ...

    Alas, even when amateur radio is the 'primary user' of a given set of frequencies, it's not a 'protected service', so the poor old ham has to grin and bear all sorts of interference, with things like Homeplugs being amongst the worst offenders. Plug them in and you will almost certainly be radiating some unwanted interference. It's only if that interfered with a primary user - police, ambulance, TV or radio broadcasters etc that someone would step in. As you have been considerate enough to sign up and ask (most don't) perhaps you might consider using a 'switch' (a box that will connect computers etc together) and lengths of CAT 5 cable. Not so neat, but usually faster and more reliable than any form of wi-fi - and no interference for any nearby hams! :) Thanks for taking the time to ask!

    Hi i am totally out my depth with HAM Radio. Only reason i signed up, was that i have been told that if i use Homeplugs to distribute my Internet/network around my house, it will cause interference to any nearby HAM Radio users, as i don't know if any live nearby, i can't go and ask them, don't want to plug them in only to find out i am blocking or interfering with their radio.

    Hi Dave, I read your reply and then opened each JPEG separately. I had to reread the reply referring to the filters which I understand now. It's never to late to put on my Christmas list. I'll need to compare the RSP1A and the RSP2 for pricing as you've stated they practically do the same options which is a good thing. I was also thinking that I would need another computer for my ham radio software and a separate display on the operating desk and leave the main computer for other things such as this forum & e-mailing friends. I wonder if you have played with the Digital Voice on the HF Bands? I have a neighboring ham who lives 1/2 mile northeast of my home and he gets on the air at 7 AM local time with many other operators and they go to each band to check the propagation around the U.S. Here's the Digital Voice website: https://freedv.org/ There's already HF Frequencies set up for the operators around the world. I want to explore the use of this mode as it uses half the bandwidth of a normal SSB...

    Hi Dan, The SDrPlay unit I went for was the RSP2 which has the additional HiZ antenna input and also more control over the front end gain. However, since my purchase they have introduced the RSP1A which has many of the aforementioned features but with only one standard antenna input - which is all you need for a tap input. When I use PSK31 most of my responses are macro based. After a very short time you build up some quite sophisticated macros negating the need to do much lengthy typing but just inserting the odd bit here and there. I am going to have a crack at FT-8 as my decoder of choice can handle this even newer mode. There is a lot of activity on JT65, getting lots of contacts deep into Russia as well as over the pond into the East coast of the US. So far my most distant decode from the UK was Tasmania on JT65. I have attached another couple of images showing the SDR narrow band selectivity. The first image shows the spectrum zoomed right in with a 250Hz CW filter applied. The second...

    Hi Dave, Well I had forgotten the fact about doing a quantity of ten boards as a first run prototype build. It's good to know that this SDRPlay Receiver will do multiple receiving modes because when I read through the information it listed AM & FM which isn't much good in the ham bands. As I read your reply this indicated to me that the SDRPlay Receiver was much like having a separate receiver to tune different bands / frequencies besides whatever you had your FT-450D listening on at the same time. I made note that the SDRPlay Receiver is manufactured in the United Kingdom (because of the VAT Tax) but I could order one (I'm not sure which one I would order) and modify my Elecraft tapping a similar location within the receive section. It might be some what more difficult to do as Elecraft doesn't supply any overlays or parts list for their equipment. Had I known this fact, I probably wouldn't have bought one on the new or used market. I discovered this fact when my Elecraft K3 took a Lightning hit so...

    Hello Dan, Apologies for not responding - I assumed the forum would email if a post was left but it didn't happen. I have attached a screen shot from the SDRPlay software SDRuno which shows the supported modes. The software covers quite a few modes AM, SAM, FM, CW, DSB, LSB, USB and digital. There are a whole bunch of other options for standard filtering or you can define your own filters - there is a lot under the hood. Since completing the mod I usually have the SDR monitoring a section of the band. If I am just receiving for fun it is very easy to see where and when QSOs are popping up and very simply to hop about with the mouse chasing conversations. Also it is handy just to pop up the band and at a glace you can see how much is going on - an active band is very easy to spot. At the moment I am really into PSK31 and JT65 especially the latter. Routing audio from the SDR into the JT65 decoder gives similar results compared with routing audio from the Yaesu into the decoder. With the CAT...

    The current draw on transmit should be reflected in the specifications (in the manual) for the particular radio. The 25W RF output is something entirely different from the amount of power consumed during transmit. If the radio has variable transmit power settings, then the specifications should reflect the current draw at each setting.

    Hello Bryan, One of my former job responsibilities while working in a Motorola R & D Lab required me to build a Portable 12 V DC Battery Pack. These Battery Packs were made up of three +12 V DC at 20 Ampere Batteries and oh man they were heavy something like 60 pounds! These Battery Packs were used in conjunction with our 25 W FM Portable Repeaters built into an attaché case that weighed 28 pounds by itself. When I would test these Repeaters, I would use the internal Power Supply and I could monitor the DC Current being drawn. As I remember the 25 W Repeaters drew 8~9 Amperes on Transmit at +13.6 V DC which was within the Specifications for the DC requirements. So when taking the +13.6 V DC times the 8 Ampere DC Current this would equal 108.8 W DC Input Power. When switched to the External +12 V DC at 60 Ampere Battery Pack, the 25 W FM Repeater would pull +12 V DC at 9 Ampere which equals 108 W DC Input. I would have to agree with Phil M0KPH that the Wal-Mart Portable Battery Pack is hardly worth the...

    Hello Dave, While scrolling through the SDRPLAY Specifications for this DC to White Light SDR Receiver (1 KHz to 2 GHz), I was looking for the modes this receiver could handle and I only found AM & FM which seemed strange. I think down at VLF Digital is used but I could be mistaken. The shortwave bands mostly used AM but our ham bands use AM, SSB, CW, FM, SSTV, ATV / DTV & Multiple Digital Formats. I'm not sure where the external SDR receiver is or has an advantage for the casual user and only having the availability of 10 MHz, this SDR receiver would be difficult to use as a Spectrum Analyzer. Your interface board turned out very well for the 7.1 MHz Injection Signal and 50 OHM Input Signals and the combination of the FT-450D & SDRPLAY appears as Standard Option. I'm almost thinking that a ham operator could do this modification to most of the present transceivers on the market today. Although many ham operators don't have access to a CNC or Milling Machine available to them so we would need to use...
