yeah the timing thing is huge and nobody really talks about it enough. what i try to do before i even transmit once is just sit on the frequency for a few minutes and figure out the DX op's pattern — are they going by region, working up the band, favoring certain calls. some of the really good DXpedition ops have a very predictable rhythm and once you lock onto it you can kinda anticipate when your shot is coming. the suffix-only thing works sometimes but honestly i've had more luck just sending my full call once, clearly, at maybe 80% of my usual keyer speed. a lot of people are hammering away at max speed and it just turns into mush in the pileup. slowing down slightly so your call is actually copyable seems to help more than raw power sometimes. i run about 400w into a 4-el yagi on 20 and i still find myself getting walked over by lid stations running a kw into a dipole if they have better timing than me. one thing i'll add — on phone pileups it's a totally different animal. i almost never bother calling at the start of a run, i wait for the pileup to thin a bit and then get in. the big gun stations will work each other at the start and then it opens up a little. patience is underrated.

yeah 10m has been really something this fall, i worked about 14 countries last weekend during a contest just casually operating, nothing serious. the flux was up around 190 which is not insane but apparently enough to get some nice F2 propagation going in the afternoon hours. your best bet is just to have pskreporter or DX maps open on your phone during the day so you can see when things are perking up without having to be glued to the radio. on the icom thing, from what i read it's more of a flagship replacement than just a refresh, supposed to have a dual receiver setup and some upgraded roofing filters. pricing is gonna be steep i'm sure. honestly i'm still happy with my 7300 for now, hard to justify the upgrade unless you're doing serious contesting or DX chasing. but new gear announcements are always fun to read about even if i'm not buying anything lol

the jitter buffer thing is almost always the culprit in my experience with RCForb. 32kbps OPUS should be totally fine for that upload speed, thats not your problem. what i'd look at is whether your router is doing any kind of traffic shaping or QoS that might be randomly throttling UDP packets — OPUS over RemoteHams uses UDP and some consumer routers get weird with it, especially if you have other stuff happening on the network at the same time. also check if you have any kind of antivirus or firewall that might be doing deep packet inspection. had a situation a while back where my security software was basically adding random latency spikes to UDP streams and it drove me nuts for weeks before i figured it out. the drops werent consistent which made it really hard to diagnose. as for the Allstar + RemoteHams question, technically you can do both but you probably want to be careful about audio routing so you dont end up with a feedback loop or double-keying situation. i havent personally run both simultaneously but i dont see why it wouldnt work if you get the PTT logic sorted out correctly.

When I first got my license back in February, I was so excited to get on the air that I immediately bought a Baofeng UV-5R and started hitting the local repeaters. That was fun for a while, but I kept hearing about HF and all the amazing contacts people were making around the world. The problem was, I had absolutely no idea where to begin with putting together an HF station. The Research Phase (aka Going Down the Rabbit Hole) I spent weeks watching YouTube videos, reading forums, and asking questions on Reddit. Everyone seemed to have different opinions about what radio to get as a first HF rig. Some people swore by the Yaesu FT-450D as a great starter radio, others recommended the Icom IC-7300 even though it was more expensive. A few suggested looking at older rigs like the Kenwood TS-440 or TS-940. The antenna situation was even more confusing. Dipoles, verticals, loops, beams - my head was spinning. And don't even get me started on all the discussions about feedline, SWR, and antenna tuners. I was starting to feel overwhelmed and wondering if I'd bitten off more than I could chew. Making Some Decisions Finally, I decided to stop overthinking it and just pick something reasonable to get started. My budget was around $800 for everything, which I knew wasn't huge but should be enough for a basic setup. After reading countless reviews, I settled on a used Yaesu FT-450D that I found on a local ham swap page for $350. The seller was super nice and even threw in a desk microphone. For an antenna, I decided to start simple with an end-fed half wave. I know there's some controversy about these antennas, but they seemed like a good compromise between performance and ease of installation for someone renting an apartment. I ordered a 49:1 UnUn kit from a small company and planned to build my own wire antenna. Setting Up the Shack The spare bedroom in my apartment isn't huge - maybe 8x10 feet - but it was enough to set up a basic station. I found an old wooden desk at a thrift store for $25 and spent a weekend sanding and refinishing it. It's nothing fancy, but it gives me plenty of room for the radio and has drawers for storing accessories. One thing I didn't anticipate was how many cables and accessories I'd need. Besides the obvious power cable and microphone, I ended up needing coax, an SWR meter, and various adapters. The local ham radio store was incredibly helpful - the owner spent almost an hour with me making sure I had everything I needed and explaining what each item was for. Power was another consideration I almost missed. The FT-450D needs 13.8V DC, and while it came with a cigarette lighter adapter, I knew I needed a proper power supply for base station operation. I found a good deal on a used Astron RS-20A linear supply. It's probably overkill for the FT-450D, but I figured it would handle any future radio upgrades. The Antenna Adventure Installing the antenna was definitely the most challenging part of the whole project. My apartment is on the second floor, and I don't have access to the roof or a yard where I can put up poles. I ended up running the end-fed wire from my shack window, around the building to a tree in the courtyard, and then back to another tree. It's not ideal, but my SWR readings are reasonable on most bands. The 49:1 transformer is mounted in a small weatherproof box just outside my window. I had to get creative with the mounting since I couldn't drill into the building, but some heavy-duty double-sided tape and a couple of zip ties seem to be holding everything securely. Getting the feedpoint impedance right took some experimenting. The antenna calculator said I needed about 65 feet of wire for 40 meters, but I ended up having to trim it a few times to get the SWR down to acceptable levels. Thank goodness for the SWR meter - I would have been completely lost without real-time feedback. First Contacts and Lessons Learned After all the setup work, making my first HF contact was incredibly exciting. I started on 20 meters in the afternoon and was amazed at how many signals I could hear. My first QSO was with a station about 500 miles away - not exactly DX, but it felt like magic compared to the 5-mile range I was used to with my HT. I quickly learned that my antenna works much better on some bands than others. It's pretty good on 40 and 20 meters, okay on 15 meters, but pretty awful on 80 meters. I think the apartment environment and low height are hurting performance on the lower bands. That's something I'll have to work on in the future. One surprise was how much difference the time of day makes. I'd heard about propagation in my license study, but experiencing it firsthand was eye-opening. 20 meters that was dead in the morning would come alive in the afternoon with stations from all over the country. What's Next Now that I have a functioning HF station, I'm already thinking about improvements. I'd love to try a different antenna design - maybe a magnetic loop for better performance in this limited space. I'm also interested in digital modes like FT8, which means I'll need to figure out the computer interface situation. The whole experience has been incredibly educational. While the technical aspects were sometimes frustrating, there's something really satisfying about building a station piece by piece and learning how everything works together. If you're a new ham thinking about getting into HF, my advice would be to start simple and don't let perfect be the enemy of good. You can always upgrade and improve things later, but getting on the air and making contacts is what this hobby is all about. 73 and hope to work you on the bands!

sounds like classic alternator whine to me. the frequency it changes with engine speed is kind of the dead giveaway. what you want to try first is getting a noise filter — sometimes called an inline noise suppressor — and putting it on the power lead. the little ones from West Mountain Radio or even the cheap ones off Amazon actually work pretty well for this. also double check where your power cable is running because if it's anywhere near the ignition wiring or the firewall grommet area it can pick up all kinds of garbage. the other thing and this is something people dont always think about is your audio ground. if the radio chassis isnt properly grounded to the vehicle body you can get a ground loop which sounds a lot like what you're describing. try running a short braided strap from the radio chassis directly to a nearby chassis bolt and see if that changes anything. mag mount antennas can also be a factor but usually that shows up more as RF getting into the audio than a hum per se.

maybe its just me but 20m has been acting strange this week. yesterday around noon i could barely hear anything then suddenly it opened up like crazy around 4pm. heard stations i never hear normally. then today its dead again. solar cycle doing weird stuff or what?
