Radio-less Full-Duplex Nodes & USB Interfaces

The UCI120 USB Communications Interface provides Hi-Fi audio quality, smooth dynamics, and an overall sound equal to or better than even the best radio nodes. These do not include a mic or speaker. I recommend a genuine Alinco EMS-57 DTMF mic which are in stock and ready to ship. For speakers I recommend any 3-8Ω speaker made by a reputable ham or commercial radio manufacturer such as Icom, Kenwood, Yaesu, Motorola, etc. Notes:

The UCI120 provides a 0/10/20dB mic gain switch and a knob enabling gain reduction/fine tuning, and provides enhanced filtering of the 5V mic power line with a 10Ω—1mF RC filter to ensure the lowest possible noise with any type of mic.

USB Radio Interfaces

AllScan URIs provide unmatched audio quality, RFI-rejection and cost-effectiveness. Comprehensive LEDs show USB host Status, COS, ADC Clip, and PTT state. Extensive I/Os fully support both HTs and mobile radios, half or full duplex. HTs connect with standard K1 2.5mm & 3.5mm TRS cables, and the URI110 and URI201 include a Mini-DIN-6 jack. Onboard trim pots support everything from mic to speaker levels and low or high impedance audio inputs and outputs. AllScan URI Configuration Settings

Perfect for use with AllScan node designs or with nearly any type of radio(s). AllScan URIs provide the most comprehensive RFI/EMI filtering available, with separate USB/Digital/Analog ground planes and power lines, ferrite beads and bypass caps on all radio I/Os, optocouplers on PTT & COS lines, and a 10Ω–100+μF RC filter on the 5V Analog supply. The URI150 and URI201 add audio isolation transformers for maximum RFI-rejection, and switch-configuration options supporting various signal and grounding configurations. The URI101/110 PCB measures only ~2"x2" - not much larger than a CM108 sound fob but with far superior RFI performance and with all I/O lines available on through-hole header pads.

AllScan URIs support AllStar, EchoLink, other PTT communications applications and interfacing of Win/Mac/Linux PCs and Smartphones to HTs, portable and mobile radios for use with remote rig control, digital modes, packet radio, etc.

With proper cabling and ferrite placement AllScan URIs typically provide 60dB Signal-To-Noise (SNR), but SNR can be significantly reduced in HT nodes if the HT is powered from the same power supply as the MiniPC/RPi. This is solved in the URI150 with full galvanic isolation including audio isolation transformers, and in the URI141 with a 0.25Ω–2.5mF RC filter on the Radio Power output.

PCB-Only Option (subtract $20) - All URIs are available as an assembled PC Board only with no enclosure or cables, LEDs included but not soldered to board. Mounting in a shielded enclosure recommended.

No Cables or Ferrites Option (subtract $10) - All URIs (except PCB-Only option) are provided by default with all needed cables and ferrite filters as listed below. The specific cables and ferrites have been optimized for each URI model and this is a significant number of additional parts, but for those who already have these items this option can save a few $. NOTE: RFI issues can be more likely to occur if not using the same or similar cables and ferrite filters.

Custom Builds

I can do custom builds with various enclosures and any other options needed. I've built nodes using a variety of communications speakers and phone patch enclosures, and include an A/B switch and external speaker level input jack so that original speaker functionality remains intact supporting use with any radio. I can also set up cloud VM nodes, repeaters, links, and custom hardware and software. Email me for details


Ordering Process, Contact Info, Payment Options

To place an order email david at allscan.info and let me know which product(s) and option(s) you'd like to go with and any other setup/configuration details needed or questions you have. I can then confirm I have everything in stock and estimated ship date. Most orders ship within 1 business day.

NOTE: If at any point you do not see a response to an email within 12-24 hours be sure to check your spam folder. I usually respond to emails within a few hours and almost always within 12 hours, but unfortunately some of the larger email providers such as GMail and Microsoft often route things to spam (even if you just sent me an email and thus would obviously be expecting a reply). If you still see no response after 24 hours please also email my other account chc_media at yahoo.com.

PayPal can be sent to paypal.me/allscan or david at allscan.info, or Venmo or Zelle to chc_media at yahoo.com. (For Zelle be sure to use only "instant" transfer rather than "standard" transfer which can take 5+ days.)

If ordering a product that includes a configured node computer please provide the following:

  1. Name, Call Sign, Email Address, Phone Number, and mailing address. (Will not be provided to any 3rd party.)
  2. AllStar Node Number to use, password defined for that node number in the ASL portal Node Settings (not your user password), and the IAX port number to use (4569 by default). NOTES:
    • The node number must not be in use on any other nodes. You can set up additional node numbers in the ASL Portal. If you have only a single 5-digit node# you can extend it there to support 10 6-digit node#s, and it's better to do this now so that you won't have to change node#s later.
    • Node passwords are usually 12 hex digits eg. 123456abcdef, must contain only letters, numbers, underscore and dash characters, and must be at least 6 characters in length.
    • The IAX port number is set on the Server Settings section of the ASL Portal. A new server entry should be created there and then in the Node Settings section assign the node number to the new server.
    • Please provide the above info in plain text (no screenshots).
  3. Confirm if you need any other ASL options, settings, or apps enabled such as EchoLink, iaxRpt or SIP. (AllScan and Allmon are included by default.) If you'd like EchoLink to be enabled, download and fill out this echolink.conf file as noted in the file comments and email to me.
  4. If you would like WiFi preconfigured, the SSID, password & password type (eg. WPA2) for your WiFi network(s). Please provide this info in plain text (no screenshots).
  5. Please confirm you have reviewed the AllScan.info website, the Instructions / Notes for the type of node you are ordering (see product pages / How-To guides), and understand how to connect the node and use AllStar.
  6. If you made a purchase through ebay please confirm if you would like any of the other options or accessories listed here on the Products page.

Note for ebay users: Ebay fees are quite high and you can save 10-15% off the prices there by ordering direct and using no-fee payment services such as venmo or zelle. Email me for details.

Terms & Conditions

I am not responsible for packages after they have been given to the post office or other shipping company. I provide a tracking number with all shipments, but in rare cases (<~2% of orders) tracking data and delivery is sometimes delayed by up to ~2 weeks. I've been doing e-commerce since 1997 and in that time have shipped over 5,000 orders, and of those less than 0.2% have been lost or damaged.

Insurance can be added to any shipment on request but I cannot guarantee that in the unlikely event of loss or damage that the shipping company will honor and pay out the claim. Because ~99.8% of orders are delivered without issue I do not by default add insurance to packages. Even in cases where the shipping company loses or damages a package they often make it difficult to file a claim and be compensated.

The signature required option can be added to any shipment on request, and is automatically added on orders over $600. If you have had any issues with reliably receiving mail and packages in the past you should probably request this option.

73, David NR9V
