Mode Designators
by Joe 04 Aug '16

04 Aug '16

While I was getting ready to activate a NO-84 Station here. I noticed my computer logging program had a small glitch with trying to log a contact on this bird. we got it semi worked out, it was the designator for the mode. ya know like Mode "A" or mode "J" etc. The program writer has many, but it did not have what this NO-84 is running and from what I see here, Designator *H* *A* *V* *U* *L* *S* *S2* *C* *X* *K* *R* Band 15 m <https://en.wikipedia.org/wiki/15_meters> 10 m <https://en.wikipedia.org/wiki/10_meters> 2 m <https://en.wikipedia.org/wiki/2_meters> 70 cm <https://en.wikipedia.org/wiki/70_centimeters> 23 cm <https://en.wikipedia.org/wiki/23_centimeters> 13 cm <https://en.wikipedia.org/wiki/13_centimeters> 9 cm <https://en.wikipedia.org/wiki/9_centimeters> 5 cm <https://en.wikipedia.org/wiki/5_centimeters> 3 cm <https://en.wikipedia.org/wiki/3_centimeters> 1.2 cm <https://en.wikipedia.org/wiki/1.2_centimeters> 6 mm <https://en.wikipedia.org/wiki/6_millimeters> Frequency (General) 21 MHz 29 MHz 145 MHz 435 MHz 1.2 GHz 2.4 GHz 3.4 GHz 5 GHz 10 GHz 24 GHz 47 GHz I'm guessing it would be mode "AU"? Now he was asking for a as complete list as possible of all modes that are possible, can anyone tell me what to tell him? he wants to add them all to his software.

How does all that work out when going to upload to LOTW? Does it automatically convert TX band to 2m, 70cm, and so on or does that also need to be done manually? Dave-KB1PVH Sent from my Galaxy S7

IC-w32A
by Kevin M 03 Aug '16

Unfortunately a lot of 5 digit serial numbers desense themselves as well... I know, I have gone through two different 5 digit models without success. The real way to tell is if a soft mod (pushing some buttons on the keypad) will open up the radio to 800 Mhz receive. When they were forced to removed the 800 Mhz capability, that is when they changed the filtering and the desense on Mode J began. Extended RX soft mod: Extended receive range (adds 300mhz and 800mhz range, mirrors celluar at 961.11-986.10) A. Turn off HT B. Hold down Main, Band, Call & Squelch while turning on HT. 73, Kevin N4UFO -------------------------------------------------------------------- Unfortunately we can't see whether or not the serial number is 5 or 7 digits. The newer 7 digit models desense themselves when transmitting on 2 meters and receiving on 70cm. 73, Paul, N8HM

The ARRL has informed me that TQSL configuration file version 9.3 will be released shortly adding support for UKube-1 in LoTW. Due to character limitations, the satellite name for LoTW will be "UKUBE1" 73, Paul, N8HM

RF Sensing Preamps, Sequencer, or both?
by Fred Castello 02 Aug '16

02 Aug '16

Hi folks, I am in the process of trying to set up a station here and have been researching equipment. While I suspect there will be a fair amount of variety, I am curious to the responses to my question: Do you use the relatively less expensive “indoor” NON RF switching preamps in an enclosure near the antennas (on the tower) with RF relays and with a sequencer in the shack (do the preamps holdup up on the tower even if protected?) OR Do you use RF sensing preamps mounted at the tower OR Both (for those that are extra careful)? I suspect operators that do other VHF/UHF low signal work tend toward sequencers (one for 2 meters and one for 440), i.e. moon bounce, meteor scatter, etc. Also, I am curious what type/brand/model of RF relays folks use? As usual, I really appreciate your time. Best, Fred Castello, KF4FC

Fred, I would guess most use RF sense switched mast-head preamps since they are using radios with a single antenna connector. But some folks modify the radio so the Rx has an independent antenna input isolated from the Tx so they can run a separate coax line to a simple preamp and use a coax relay on the antenna side of the preamp. This requires a separate coax run to the Tx output. This second approach is not uncommon approach for those involved in serious weak-signal VHF+ operating (which includes eme). I have both approaches at my station. I have several DEMI transverters that provide separate Tx and Rx antenna connection so a simple remote located preamp with TR relay can be used. But I also have a FT-736R (unmodified) which can use a yagi with Rf sense-switched preamp and only requires one coax run. I do have external switching control line to that preamp which will require adding ext. PTT from the FT-736R. I originally used preamps for 144 & 432 with separate TR relays for my AO-40 era satellite set up and will be restoring that this summer. This will require modifying my FT-736R. I use a station control panel with integrated sequencer, but that was done for eme and other weak-signal operation (not specifically for satellite). My satellite control ckts will utilize the sequencer (which provides extra protection to the preamps - but not normally used by satellite stations. 73, Ed - KL7UW From: Fred Castello <fredcastello(a)gmail.com> To: "amsat-bb(a)amsat.org" <amsat-bb(a)amsat.org> Subject: [amsat-bb] RF Sensing Preamps, Sequencer, or both?
