  1. Depending on how the radios are programmed, one of two things will happen. In one instance, a radio with a busy TX inhibit would sense the (already present signal) keep the radio from keying altogether while keeping the squelch closed. In the other, the two signals would mix and it may or may not open squelch properly on the receiving end depending on the FM capture effect.
  2. To someone listening CSQ, an ID is an ID regardless of PL. If your ID is sent with PL, then people using a different PL wouldn't hear the use (unless RX is set to monitor). If the system ID's without a PL those using any RX PL will never hear it. Sent from my iPhone using Tapatalk
  3. At some point I'll be adding another. Sent from my Venue 7 3730 using Tapatalk
  4. Gotta love hand held control heads. http://i1245.photobucket.com/albums/gg586/zap_uh_lack/New%20Truck/10E5FDF4-59D8-4753-ACA9-6859926D8AC6_zpsb2nae2qk.jpg
  5. It's based off of number of posts I believe.
  6. Those are all pre-1989 definitions from back when you had to register location information with the commission. The rules need to be gone over with a fine toothed comb (most grandfathered licenses are renewed simply to keep them from laspsing but most have moved onto Part 90 systems). Most of what c and d reference has been removed from the current rules. From what I've heard talking to some Canadian friends, e no longer applies as they have adopted a similar power regulation on the band.
  7. There is a cluster of confusion in the rules. You can read the rules like many read the constitution (if it doesn't say you can't do something, then go ahead or by only what is there in print). In Part 95A the rules actually say that transmitters must only be certified for use in GMRS and then in the next sentence it states the rules must only meet the technical standards for GMRS...so the two sentences contradict one another. If you actually dive down into the technical standards, then they actually require a crystal controlled radio (which I might add, most of the FCC OET database only goes back to 1982 when radios began to become synthesized) but we know that since the rules were written in 1989 that Motorola, Icom, Kenwood, Standard Horizion (Vertex), and General Electric (Harris) have all manufactured synthesized radios with 90/95A certification. As a result, many just run whatever Part 90 radio they can get their hands on (because they meet technical specifications).
  8. Yea and no. If you are trying to cover a valley/bowl, the best location is in the middle or on a small hill in the valley. GMRS is pretty much line of sight communications so we tend to design with that in mind. Sent from my iPhone using Tapatalk
  9. Yea, but he specifically said amateur and 2m. Sent from my iPhone using Tapatalk
  10. You can generally find Icom F21 HTs for around $40 at ham fests. I paid $70 for a F21GM (if FPP is needed).
  11. Is anyone else curious to how that worked? You need like 3 MHz offset to use flat packs on VHF...
  12. Depends on application. I've become fond of the Simoco XD repeater's (DMR) due to their analog networking capability. They make 25W and 50W versions. If the rules change easy to setup for digital (while remaining networked and being used for analog as well). Plus, they MSRP for $2300. Good locations are key though. For a portable setup, I'm hoping the Hytera manpack gets cloned by Technet in some manner since I've been bugging them about it for so long. Sent from my iPhone using Tapatalk
  13. There was actually a glitch in the system yesterday morning that allowed for Part 95 licenses to be applied for without a fee associated with them. It has since been returned to the $65 price point.
  14. Easy to make digital repeater? I could use some info on that as the only semi portable repeater I'm aware of for DMR is from Hytera whom the rumor is just fired all their U.S. Sales reps and a lot of the U.S. Based support. Sent from my iPhone using Tapatalk
  15. Dual boot my MBP…handles pretty much all of my programming needs. Everything that needs a real serial port, I have a cf-28 for. Sent from my iPhone using Tapatalk

  18. Pick a regular PL'ed output and a DPL on the input. For one this opens one up for any HT that you may be able to program (not all radios offer MDC signalling). MDC1200 would be a fun setup. It can be set on most MDC capable repeaters, especially those built with MDC capable receive and transmit radios.
  19. The T1504A is actually the model number for the band pass filter in the T1500 seires of filters. I've got a T1504A band pass filter but I'm missing the rest of the set.
  20. If just CW, look at the comspec ID-8. When you actually factor in what your time may be worth to you, much more than a half hour build time and the ID-8 is cheaper. Sent from my iPhone using Tapatalk ETA: After re-reading the rules, there is nothing that says an ISM (Part 18) device can't be used for creating cross banding links.
  21. From what I remember, that would be correct. I know linking into the commercial service is not forbidden specifically. Not sure if linking into other part 95 services is addressed in 95A. I know it is addressed in 95J (MURS).
  22. All the rules (Part 95A) say is really you can not tie into the amateur radio service (Part 97). MURS (Part 95J) rules do specifically forbid any kind of repeating (including cross banding into another service). However, the rules for GMRS don't actually prohibit one from tying a Part 90 service into Part 95A. As far as the technical aspect goes, one alternative would be to try some vertical separation (about 10 feet should be adequate)with the Baofengs if one did not want to go through the trouble of purchasing a duplexer. Even at low power you will most likely blank the front end of the receive radio with both being in the same horizontal plane with 20 ft of one another.
  23. PA is good (if they are like the Micor then they will require 1-2W to drive). Station conversions aren't bad, I've got a few of them but mine are on the Micor platform though. Has a ARS pre-amp (those are worth a little money, seeing great benefits when using preamps on TDMA repeaters). There are some good parts in there that are certainly worth saving.
  24. The KML output only works if you run a regular splat command (not splat-hd). Also, there is a bug somewhere that if you try and copy or move the KML file it'll corrupt the file.
  25. Repeater-Builder should have some info on the MSF line.
