    Hello, I posted in the ICOM forum, but no one could help (with the following problem), therefore I wanted to ask if somebody here has an idea. I'm using a SDR created with GNUradio to transmit and receive GMSK signals in FM-D mode between an ICOM IC-7100 and IC-9100. If the signal from the SDR is send to the IC-7100 as audio signal from the pc soundcard via an audio connection to DATA2 socket, the signal is correct transmitted to the IC-9100 and the input of the receiving SDR (connected via USB-cable to the IC-9100) is shown in following link. Example for klinke audio connection If the same signal is send to the IC-7100 via a USB cable to the USB-port to use the internal soundcard, the received signal at the IC-9100 is not correct. Example for USB connection

    As all of these links are now dead, and sadly we can't get to Tony's (SK) original document, I wonder whether it's worth having a new Sticky post, with fresh info? Thanks, Chris 2E0FRU

    I have a VHF/UHF antenna (ANLI A-100) and was checking on it with my antenna analyzer (N1201SA) through 50ft of Mini-RG8x feed line. (Antenna is in attic area 30 feet up from ground) I was expecting the standard curve showing an optimal SWR in the VHF and UHF bands. I did get this for the VHF band but the UHF, while under a SWR of 2, produce a rippling pattern across the band. I am new to antennas so I thought Iíd ask here from the most knowledgeable so... What can be inferred from analyzer scan showing multiple minimum SWR (ripple) across a band?

    Hello, I got comparable results while using the IC-9100 to send and the IC-7100 for receiving. Any ideas how to fix the USB connection? Thanks for your time and help. Best regards Steffen

    Rgr Iíll have to give that a go. Read there is an internal fuse or also something about an external power switch but I wasnít able to find either of those. Iíll give them a call and see what they say. Thanks for the help. Sent from my iPhone using Tapatalk

    Contact Yaesu Repair. They might be able to give you some insight. And they could certainly repair the radio if it needs it.

    Just got a new battery pack in the mail today. Threw in some brand new batteries and still nothing. Beginning to think I somehow burnt the part of the radio that looks for the battery. It no longer will run off a battery. Only off the cigarette plug. Any ideas on fixing this or is it toast? Sent from my iPad using Tapatalk

    I have been hunting eBay, Craigslist, and other markets looking for a nice starter HF Rig to get on air and make some contacts and I found alot of these S and D (G) models. It seams like these radios offer the bands I want and the options needed to start making some DX contacts and learning the basics of antennas and such. Has anyone had one of these radios are they a good starter? Are they forgiving to a newbie or super complex to work? How do they interface with computers? I am considering this as a viable first rig as the prices look pretty good, and really would appreciate some wisdom from others who have experience. Sent from my XT1635-01 using Tapatalk

    Good morning, I'm happy to say I just got my offical copy of my license and new call sign. Saturday I sat for my Technician and General and passed both. I look forward to getting into EMCOM and DX and will be here reading and asking as I select my transceivers, build my HF antenna and try to get on air in the coming weeks. I look forward to to jumping into this great hobby. 73, Corey Sent from my XT1635-01 using Tapatalk

    In these cases, we always ask the same question. Who, exactly, do you wish to talk to? People local to you? People further away, or even people in foreign countries? Do you have facilities to charge batteries? Is weight a consideration? Can you climb trees or find ways to erect antennas? Perhaps you could tell us what you can already do, and how you want your purchase to work?

    I am stumped as is Kenwood technical support. My TS-2000 transmits fine on all my MARS frequencies EXCEPT 60m!It has the MARS mod. WHen I try to xmit on 5mHz, the red xmit light comes on on the rig, but the txvr is not putting out any power on that frequency.I have played around with different MIC Gain settings, but that has no effect. I'm frustrated.

    My Paragon has been boxed up for almost ten years. I recently got licensed again. I thought my radio had a problem on 75 when I put it away but couldn't remember for sure. Today I broke her out and powered up. PLL out of lock came up. Bad solder joints was one response and another was "mine does it occasionally but not issues after its been on for a few minutes". So I walked away from mine for 5 minutes. I came back and it was displaying properly. A friend showed up with a dummy load and I started through the bands. I'm good everywhere. Yippee. That stuff doesn't usually happen to me. Now if I can just get the string replaced on my tuner so the dial moves I will be 100%. Gotta get some antennas up and get on the air. (Right now I run coax out the door to a Hustler mobile on a magnet stuck to whatever is parked close enough :redface-new:)

    You could try building an external BFO for a small handheld-type MW radio. Tuning the radio on frequency would be the most difficult thing, but one thing to consider is stability - FAX requires a fairly stable tuner, or the colours fade. I can't find a circuit diagram on Google (amazingly) but I built one using a 555 timer IC decades ago which worked very well - look for a 455kHz beat frequency oscillator...

    I own 4 of these radios, 3 of them for over a year. There is no way to set different tones for transmit and receive frequencies in the same memory channel. The tones for 'T' and 'CT' must both be the same for any specific memory channel. The work around is to simply use the 'T' function and leave the receive side open.

    It may be worth noting for those who own the TM-V71A as I do (I own 4 of them) That they cannot be programmed to have separate Tx and Rx tones on the same memory channel for a repeater. Some repeaters in the areas I frequent have different tones for Tx and Rx on purpose. The only work around I have foud is to use the "T" function which is tone encode only. This leaves the receive frequency open to everything heard on that frequency. Programming a repeater frequency as an "odd split" does not work in attempting to have separate Tx and Rx tones.

    Sometimes a large number of relatively short radials will outperform just one or two radials of textbook length. As long as you can make them - and you can bend them a bit, just to include the amount of good conductor in the soil. I would recommend trenching them in little slits in the turf with a few lawn staples to keep them where they need to be. Let the grass grow up and around them. Just don't forget, if you're planning to prepare a garden in a few years! You'll find your radials....

    I have a 48 foot vertical, but have very limited real estate area for laying ground radials. Are ther other acceptable options besides laying multiple 1/4 wave radials? I would even consider a different type of antenna. My antenna is only a few feet from my 26 foot tall house. Thank you for your help! Butch Reed KF5NRP

    Hi, I am wanting to do a small project with a raspberry pi or the like. I want to be able for it to run and receive Navtex (490 and 518 Khz) and Wefax (lower still). One simple solution would be to get a device such as a Tecsun pl-680/880 and tune to the relevant frequencies, but, that can mean leaving the radio and PI on all the time and I want to have this as a low consumption project. The PL-880/680 is also rather expensive and I have not found another radio that does 518/490. Many short wave radios but not all will do wefax frequencies, but I found no radio other then the PL680/880 that did the navtex and also even the wefax signal strength is poor on even a Tecsun pl606. Does anyone know a simple cheep radio that could be hooked up to an audio port that could receive on the relevant frequencies as a first step. I would also want this to be portable so this should be battery powered? I have considered kit radios or old transistr radios, perhaps modifying with a simple capacitor an analogue...
